Los Angeles Dodgers vs. Milwaukee Brewers
This is the Brewers’ second showdown with the Dodgers in the NLCS, the first a seven-game loss to L.A. in 2018. Since Milwaukee started its run of contending seasons in 2017, only the Dodgers have won more regular-season games in the National League. The Brewers haven’t been able to translate that tap-tap-tapping at the championship door into a World Series crown, and twice their season has been ended by the Dodgers behemoth. L.A. entered the season with all the hype, but the Brewers exited it with a No. 1 seed. Seems easy to say now that it has come to pass, but wasn’t this always going to be how the Brewers got back to the World Series? — Bradford Doolittle
No. 1 seed Brewers’ concern level: None. Why should the Brewers be worried? Forget the seeds, the records, the run differentials — Milwaukee will enter this series perceived as a decided underdog. That’s not based just on what we’ve thought the Dodgers would be since last winter, but because of how L.A. has rolled through the beginning of its latest postseason run. But you know who else is rolling? The Brewers. And they are too young, too athletic and having too much fun to be intimidated by the Dodgers’ hype aura. Of more immediate concern, from a baseball perspective, is the fact that L.A. is awfully good. — Doolittle
Los Angeles Dodgers
Odds of advancing: 48.2%
Team temperature: 110°
What stood out most as the Dodgers rolled past the Phillies in the NLDS?
Jeff Passan: The team that the Dodgers were supposed to be has shown up in October. It’s not just the talent, which itself can be overwhelming. It’s that they are particularly comfortable in the sorts of games that would have others panicking through an expanded zone at the plate or too-fine nibbling on the mound.
Philadelphia’s starting pitching was excellent, and that still wasn’t enough to stop the Dodgers. And considering L.A. has done it without significant contributions from Ohtani or Betts over the first two games**, and with a bullpen that beyond Roki Sasaki and Alex Vesia remains in flux, the prospect of the Dodgers getting better is very real — and very scary.
David Schoenfield: Their ability to eventually get to the starting pitcher. In Game 1, Cristopher Sanchez was cruising through 5⅔ innings, having allowed just four hits. Then with two outs in the sixth, Freddie Freeman worked a walk, Tommy Edman singled and Enrique Hernandez drove both in with a double. The Dodgers then later added three runs against the bullpen.
Jesus Luzardo had been even more dominant in Game 2 with one hit allowed and 17 consecutive batters retired entering the seventh, when Teoscar Hernandez singled and Freeman doubled to chase Luzardo from the game. The bullpen entered and the Dodgers eventually scored four runs in the inning. Going back to last year’s postseason, Freeman seems to be involved in so many of these rallies while both Hernandezes become tougher outs in the postseason.
Why will (or won’t) it work against the Brewers in the NLCS?
Passan: The Brewers have a more balanced offense and a far better bullpen than the Phillies, and each is the sort of thing that could trip up Los Angeles. Now, admittedly, Milwaukee hasn’t faced the caliber of pitching the Dodgers present, so their NL-best strikeout rate this postseason will climb. And the Dodgers hit high velocity about as well as any team in MLB, so the advantage there for the Brewers — who are averaging more than 97 mph on their fastballs this postseason — isn’t quite as acute. The brand of baseball the Brewers play can work against Los Angeles. The execution simply needs to be immaculate.
Schoenfield: There are two factors in play here. The Brewers’ starting pitching isn’t as good, so manager Pat Murphy will be much quicker to his bullpen even if the starter is pitching well. The Brewers’ bullpen is much better and less likely to hemorrhage runs late like the Phillies did. So the «score late» philosophy is probably less likely of an outcome. Which puts pressure on the Dodgers’ offense to put runs on the scoreboard early in the game.
Which one player is the X factor who can make (or break) L.A.’s World Series hopes?
Passan: If Ohtani continues to disappear — he is in line to make two starts in the series and will continue to bat leadoff — the Dodgers have enough talent to overcome it, but their margin of error shrinks significantly.
He is the one player in baseball capable of single-handedly winning a series, and with his fastball sitting at career-best velocities even after his second reconstructive elbow surgery and his off-speed stuff still elite, he can control multiple games with his arm in addition to his power serving as an ever-present threat.
Poor pitching performances, on the other hand, can lose games, and lack of getting on base by a leadoff hitter hampers the ability of Mookie Betts, Teoscar Hernández and Freddie Freeman to do damage. The difference between good Ohtani and bad Ohtani is profound enough to dictate the result of the series.
Schoenfield: Emmet Sheehan. Dave Roberts has found a closer in Roki Sasaki, and Alex Vesia is the one lefty he seems to trust, but it seems unlikely the Dodgers can win a World Series with just two relief pitchers.
Tanner Scott, the closer for most of the season, has been buried on the depth chart. Roberts went to Blake Treinen in Game 2, and he nearly blew the game.
Sheehan now looks like the top right-handed setup guy. He’s going to pitch some important innings. The regular-season numbers, mostly as a starter, say he can do the job: a .185 batting average allowed and 89 strikeouts in 73⅓ innings.
Milwaukee Brewers
Odds of advancing: 51.8%
Team temperature: 74°
What stood out most as the Brewers beat the Cubs in the NLDS?
Jesse Rogers: The Brewers came out with their hair on fire in the division series, not letting getting down early in Games 1 and 2 — after a week layoff — didn’t faze them. Most interesting was their power surge in the series. Solo shots and three run homers were all the rage for the Brew Crew. Add the fact that Milwaukee deployed one arm after another throwing around 100 mph — starting with righty Jacob Misiorowski — and the Chicago Cubs were overwhelmed in the strike zone, both at the plate and on the mound.
Schoenfield: Scoring nine runs in the first game without hitting a home run and then scoring seven runs in Game 2 all via the home run was impressive, but no doubt it’s those power arms in the bullpen that offered a huge exclamation point. Misiorowski threw an incredible 31 pitches over 100 mph in his three-inning stint in Game 2, including two at 104.3 and 104.2 mph. Trevor Megill is back after missing more than a month and hit 98. Jared Koenig hit 99.8. Abner Uribe throws a 99-mph sinker with a wipeout slider. Good luck.
Why will (or won’t) it work against the Dodgers in the NLCS?
Rogers: Umm, hitting home runs and throwing 100 mph? That works against anyone. Of course, there’s a good chance the Brewers won’t hit as many long balls but that’s when they’ll rely on the other parts of their game: contact, speed and defense. And if confidence matters at all, Milwaukee swept the season series against L.A, providing further hope in the NLCS. If somehow they can continue to go deep, watch out, an upset might be, ahem, Brewing.
Schoenfield: Bullpens can get hot in the playoffs, and it looks like the Milwaukee bullpen is hot. It’s worth noting that the Dodgers had the third-highest OPS in the majors during the regular season against pitches of 97-plus mph, hitting .255/.330/.429. So the Dodgers can do some damage against premium velocity. Of course, 104 is a different beast. Still, it feels like the Dodgers will have to score some runs early in the game to win this series.
Which one player is the X factor who can make (or break) Milwaukee’s World Series hopes?
Rogers: Jacob Misiorowski. It’s clear he’s going to have an important role no matter how the Brewers elect to use him. If he can control his emotions, as well as his stuff, Misiorowski could be the bridge to the late innings in several potential Brewers wins. Or perhaps they let him start a game. Dodgers hitters are 4-for-17 with eight strikeouts this season against the rookie. More of that — along with fastballs at 103 mph or more — could help Milwaukee through a tough L.A. lineup.
Schoenfield: Jackson Chourio. There was a scare in Game 1 when Chourio left the game after tweaking his hamstring (after going 3-for-3) but he returned in Game 2 and had two more hits, including a big three-run home run in the fourth inning.
Still just 21, Chourio is already showing a propensity to shine in the October spotlight. In his first five career playoff games, he had multiple hits in four of them (including a two-homer game last year against the Mets). We’ll see if the Dodgers can exploit his tendency to chase out of the zone but if he keeps producing, the Brewers will score some runs.
Toronto Blue Jays vs. Seattle Mariners
At last! Super-fans of 1977 expansion have been waiting for this LCS matchup since the early days of the Carter administration. The Blue Jays and Mariners came into existence at the same time, but they have never met with stakes like these in play. The M’s beat the Jays in a wild-card round matchup in 2022, but this is different.
The two strongest division champs in the AL are vying to end long World Series droughts. Toronto hasn’t won the title in 31 years, and Seattle has never won it.
The great Willie Horton was among the first players to play for both franchises. Even though he’s best remembered as a Tiger and has a statue outside of Comerica Park, they should still let him throw out the first pitch in Seattle and Toronto. — Doolittle
No. 1 seed Blue Jays’ concern level: Appropriately alert. Toronto has the better seed and home-field edge, but Seattle has been playing slightly better in the latter stages of the season, and the run differentials are virtually the same.
What’s really exciting is the star power on both teams and that the standouts have been shining in October. Julio Rodriguez, Cal Raleigh and the scorching Vladimir Guerrero Jr. have played huge roles in the teams getting this far.
Both teams have leaned on the long ball for scoring, getting more than half their runs on homers. It’s a really close matchup that could be decided by Andres Munoz, Seattle’s edge at the back of the bullpen. — Doolittle
Toronto Blue Jays
Odds of advancing: 55.1%
Team temperature: 96°
What stood out most as the Blue Jays rolled past the Yankees in the ALDS?
Jorge Castillo: The relentlessness of their lineup. Vladimir Guerrero Jr. starred from start to finish, but Toronto received contributions from seemingly everyone manager John Schneider put in there. Four players not named Guerrero recorded two hits in Game 1. Daulton Varsho had four extra-base hits, and Ernie Clement went 3-for-4 in Game 2. Clement added another four hits in Game 3.
The Blue Jays were the toughest team to strike out during the regular season, and they registered more home runs than strikeouts in the first two games at Rogers Centre, where they’ve thrived all season. It helped that Playoff Vladdy Jr. surfaced, going 9-for-17 with three home runs, including a monumental grand slam in Game 2.
Schoenfield: Have to go with Trey Yesavage‘s absolutely dominant performance in Game 2, when he made his fourth career start and held the Yankees hitless for 5⅓ innings while striking out 11. The Yankees had no chance against him. Other than the length of the start — the Blue Jays pulled him with a big lead — it was as dominant a postseason outing as we’ve seen in a long time.
His over-the-top delivery creates an unusual look for batters, and he’s throwing 95-96 mph with a slider and wipeout splitter. Hard to believe there were 19 players selected ahead of him in the draft in 2024.
Why will (or won’t) it work against the Mariners in the ALCS?
Castillo: It’ll work at Rogers Centre because it has always worked at Rogers Centre this season. The Blue Jays scored 431 runs at home during the regular season, the third most in the majors. In the ALDS, they scored 23 in two games in Toronto. The Blue Jays dominate pitchers north of the border. The question is whether it’ll work in Seattle. T-Mobile Park is a difficult place to hit. Mariners pitchers posted a 3.28 ERA at home this season. But the Blue Jays scored 21 runs in a three-game sweep of the Mariners in May. Maybe their offense will travel.
Schoenfield: It will … if he throws strikes. He did against the Yankees, walking just one batter in his start, but in the minors, he walked 41 batters in 98 innings. The Mariners have a mix of patient hitters (Cal Raleigh, Randy Arozarena) and hitters who chase (Julio Rodriguez, Eugenio Suarez), but like the Yankees, the Mariners also whiff a lot.
Which one player is the X factor who can make (or break) Toronto’s World Series hopes?
Castillo: Trey Yesavage. Asking a rookie with four major league starts to continue dominating deep into October is a lot, but the Blue Jays lack that clear premier ace. Yesavage has the potential to supply it. Not only is his stuff good enough, he’s different enough to flummox even the most experienced hitters. His release point and arm angle are among the highest in baseball, making his fastball-splitter combination especially difficult to solve. Then, there’s his slider, which often runs arm side instead of the usual glove side. Toronto has been careful with the 22-year-old right-hander. He hasn’t thrown more than 94 pitches in a game this season, which started for him in Low-A. Now, he’s on the sport’s grandest stage and could be the difference in October.
Schoenfield: Shane Bieber. Kevin Gausman and Yesavage looked great, but given a 6-1 lead in Game 3, Bieber got knocked out in the third inning. Given how poorly Toronto’s bullpen pitched after that, maybe it was a bit of a quick hook, but it’s clear the Blue Jays will need all three of these starters to pitch well, given the bullpen didn’t post a bunch of zeroes against the Yankees. The Blue Jays’ ability to put the ball in play — they had the lowest strikeout rate in the majors — means they should continue to score some runs, so the question is whether they can keep enough runs off the scoreboard.
Seattle Mariners
Odds of advancing: 44.9%
Team temperature: 89°
What stood out most as the Mariners beat the Tigers in the ALDS?
Alden Gonzalez: The effectiveness of the starting rotation, which should come as no surprise. George Kirby, Luis Castillo, Logan Gilbert and Bryce Miller — before the fifth inning, at least — all pitched well in the ALDS. The hope is that Bryan Woo, the Mariners’ best starter this season, will return from a pectoral injury for the ALCS, taking this rotation to yet another level.
The Mariners feel really good about their back-end relievers and believe this is the deepest lineup they’ve fielded in this era. But this team still revolves around its starting pitching — a unit that dominated throughout 2024 and finally started to round into form again in the stretch run of this season. The starters need to consistently provide six and seven innings so that manager Dan Wilson doesn’t have to venture outside of Gabe Speier, Matt Brash and Andres Munoz late in games. That’s the formula.
Doolittle: Seattle’s lineup depth is really impressive, even without a standout designated hitter. It’s eye-popping to see Eugenio Suarez hitting in the six-hole and J.P. Crawford at No. 9. It’s a group that hits for power, steals bases and strikes out at a much less problematic rate than the Mariners lineups we’re used to. Raleigh and Rodriguez make for such a dynamic one-two stack in the batting order. The R&R Boys.
Why will (or won’t) it work against the Blue Jays in the ALCS?
Gonzalez: No team struck out less often than the Blue Jays this season. Only the Yankees and Dodgers finished with a higher OPS. And when the playoffs arrived, Vladimir Guerrero Jr., Ernie Clement and Daulton Varsho slugged a combined 1.000 in four ALDS games. This offense operates at a different level than the Tigers’ — and could have Bo Bichette back for this next round.
Gilbert and Woo pitched pretty well against the Blue Jays this season (five earned runs in 11 2/3 innings). Castillo and Miller (15 earned runs in 15 innings) did not. But these two teams have not seen each other since May. The Mariners’ rotation is not the same as it was then.
Doolittle: A deep lineup plays against anybody, but there’s one factor that works in Seattle’s favor. With Trey Yesavage emerging for Toronto, the Blue Jays have four key hurlers who can dominate with splitters, the breakout pitch of the 2025 postseason. (Yesavage, Kevin Gausman, Seranthony Dominguez and Jeff Hoffman are the four.)
The Mariners were in the middle of the pack in hitting splitters during the season, but they had two hitters who crushed them. And it’s the R&R Boys — Raleigh had 1.159 OPS against splitters and Rodriguez 1.091.
Which one player is the X factor who can make (or break) Seattle’s World Series hopes?
Gonzalez: Randy Arozarena. The Mariners inserted Arozarena at the top of the lineup after they acquired Eugenio Suarez and Josh Naylor at the trade deadline, and Arozarena has struggled mightily ever since. He showed some flashes in the ALDS, but the Mariners need «Playoff Randy» — the one who took over during the 2020 postseason and became a sensation while playing for Team Mexico in the 2023 World Baseball Classic. If he gets going ahead of Cal Raleigh and Julio Rodriguez, the Mariners’ offense will be scary.
Doolittle: Matt Brash. Well, that’s not fair, as Brash is good, and I picked his name as an avatar for Seattle’s middle relief crew. If the Mariners’ roster has a soft underbelly, it’s the non-closing part of the bullpen. It’s not a bad group, but with a deep, productive lineup and a star closer in Munoz, plus excellent starting pitching, it might well be Brash, Eduard Bazardo, Gabe Speier and Carlos Vargas who determine if the Mariners can finally play in a World Series.
