NEW YORK — The Yankees’ road to an AL-best 94 wins wasn’t the smoothest ride. They overcame significant injuries, and at times dealt with a lack of production from just about everybody besides Aaron Judge and Juan Soto. Even as they fought off the Orioles for the AL East flag, they struggled to find the right mix in the bullpen, as All-Star closer Clay Holmes suddenly struggled to lock down the ninth inning. A September shuffle that put Luke Weaver in the closer’s slot has paid big dividends, however, and so far in this postseason, the Yankees bullpen has been a difference-maker. In Monday night’s American League Championship Series opener against the Guardians, Weaver notched a five-out save to preserve a 5-2 victory.

The 31-year-old Weaver — a former first-round pick who until September 6 had never recorded a major league save — has pitched in every Yankees playoff game thus far. He closed out all three Division Series wins against the Royals, going four outs in Game 1 and five outs in Game 3; he also made a one-out cameo in Game 2, New York’s lone defeat. In six shutout innings, he’s allowed just two hits and one walk while striking out nine of the 21 batters he’s faced (42.9%).

In fact, the Yankees bullpen has allowed just two runs (one unearned) in 18 2/3 postseason innings, for a 0.48 ERA. The unit as a whole has surrendered just 11 hits and five walks while striking out 20 (28.2%). Holmes, like Weaver, has pitched every game and has thrown six scoreless innings himself, striking out four while yielding just three hits and one walk.

“Comfortable is not quite the right word. I think tonight was a little bit of a grind for me personally,” said Weaver of Monday night’s 24-pitch save. “I felt really good coming in in the eighth. The ninth, coming back out for the first hitter was a little sloppy, I think that was noticeable. The windup just felt a little funky. I felt the adrenaline coming out of the eighth, (but) going back out for the ninth, was a little depleted… I felt like it was a tick down.”

After Weaver walked Lane Thomas on five pitches to lead off the ninth, he gave himself a bit of a pep talk, flashing a bit of humor as he explained. “So when Thomas got on, it just became like, ‘What are we doing? The fans don’t come here to watch that.’ So I was able to throw some good pitches, and was looking for the double play, but was able to get these good counts.”

Weaver went long because the Guardians had threatened to tie the game. Starter Carlos Rodón had dominated for six innings, holding Cleveland to just three hits while striking out nine without a walk, generating 25 whiffs along the way; meanwhile the Yankees built up a 4-0 lead against starter Alex Cobb and reliever Joey Cantillo, who threw four wild pitches and walked three while retiring just one hitter. The Guardians cut the lead to 4-1 when no. 9 hitter Brayan Rocchio led off the sixth inning with a solo homer off Rodón.

As was the case in the Yankees’ two ALDS wins in Kansas City, Holmes was the first number called by manager Aaron Boone. He didn’t waste much time, inducing Thomas to hit his second pitch, a 96-mph sinker on the outside edge, for a soft groundout. He fell behind Josh Naylor 2-1 before Naylor lined a high-and-away sinker to center field for a routine out. Holmes capped his night by battling pinch-hitter Kyle Manzardo (hitting for right fielder Jhonkensy Noel) for eight pitches before striking him out chasing a low-and-inside sweeper.

“He’s been the nastiest guy we’ve had out there,” said Weaver of Holmes’ middle relief work. “He’s absolutely setting the tone.”

With no off day before Game 2, and with two lefties and a switch-hitter looming, the lane was clear for lefty Tim Hill to pitch the eighth. Guardians manager Stephen Vogt swapped out lefty Bo Naylor for righty Austin Hedges, an even weaker hitter despite the platoon advantage; he flied out. Andrés Giménez followed with a single, and then Rocchio shot a single under the glove of first baseman Anthony Rizzo, who was back in the lineup for the first time since fracturing two fingers on his right hand on September 29. Rounding first, Rocchio made contact with Hill, who in moving to cover the bag ended up right in the baseline. Though the pitcher had the ball and tagged Rocchio once he retreated, the umpires ruled he had already committed obstruction, and awarded Rocchio second base.

Giménez scored on Steven Kwan’s single, offsetting Giancarlo Stanton’s solo homer in the top of the frame; it was the first earned run surrendered by the Yankees bullpen this postseason. That prompted Boone to summon Weaver, who fanned pinch-hitter Will Brennan (batting for David Fry) on three low pitches, the last a changeup in the dirt, then induced José Ramírez to ground out to second base.

In the ninth, after walking Thomas, Weaver recovered to strike out the side. Naylor chased a low-and-away changeup. Daniel Schneemann battled to a full count, then tipped a 95-mph four-seamer into Austin Wells’ mitt for the second out. Finally, Weaver blew Hedges away on three pitches, giving the Yankees a 1-0 series lead. 

Afterward, pitching coach Matt Blake praised Weaver’s command as the key to his success in working long. “His ability to get in the strike zone early and be effective and be efficient with his pitch counts — he can collect outs quickly and he’ll strike guys out, but he doesn’t have to do seven or eight pitches to get there.”

While the save may not have been easy, Weaver still looked like a pitcher who had been doing the job of shutting the door for much longer than six weeks. A year ago, the role would have been unthinkable. Weaver was designated for assignment twice in 2023, first by the Reds on August 16 — a point at which he briefly wondered if he’d reached the end of the line — and then by the Mariners on September 10. Even with three solid September starts for the Yankees, he finished with a 6.40 ERA, his second season in a row and his third out of four above 6.00; to that point across eight partial seasons in the majors, he owned a 5.14 ERA in 574 1/3 innings, mainly as a starter.

The Yankees had seen some traits in Weaver’s spin rate, arsenal, and clean mechanics that they believed they could tweak, and Weaver embraced the possibilities. Over the winter, he simplifid his delivery, ditching a high leg kick and adopting a slide step. He also adjusted the grips of his four-seam fastball — previously, his middle finger wasn’t in contact with a seam, costing him spin efficiency — and his changeup, helping him generate more spin. Needing to throw 15–20 pitches per outing instead of 80–100, he gained velocity, and recovered more quickly. Two weeks ago, Weaver likened the streamlining to a runner with smoother, tighter arm swings and less wasted energy.

Working out of the bullpen allowed Weaver to ditch his less effective knuckle curve, slider, and sweeper. The changes “helped bring some earlier contact, less foul balls, less getting beat on the pitch,” as he said on Monday. “I think it’s really just the perfect storm of better movement and more confidence.”

For the season, Weaver pitched to a 2.89 ERA and 3.33 FIP with a 31.1% strikeout rate in 62 appearances totaling 84 innings. As Marquee Sports’ Lance Brodzowski noted, the vertical separation between Weaver’s fastball and changeup increased from about 8 inches last year (16 inches of induced vertical break for the four-seamer, 8.2 for the changeup) to about 14 inches this year (18.6 inches for the four-seamer, 4.6 for the changeup). The results on those two pitches improved dramatically:

At the outset of the season, the Yankees saw Weaver as a potential sixth starter who could provide multiple relief innings in lower-leverage situations. He allowed seven runs in 10 2/3 innings over his first six appearances, but graduated to a higher-leverage role by reeling off 18 consecutive scoreless innings from April 20 through May 20, giving up just five hits and two walks while striking out 24.

Weaver endured some midseason ups and downs, posting a 3.66 ERA and 4.60 FIP across 32 appearances from May 22 through the end of July. Meanwhile, a whole drama unfolded around Holmes. Through June 9, the 31-year-old sinkerballer allowed runs in just two of his first 30 games, posting a 1.23 ERA and 2.22 FIP. Despite scuffling a bit over the rest of the first half, he made his second All-Star team in three years on the strength of a 2.77 ERA and 2.73 FIP. Even so, he’d already set a career high with six blown saves in 27 chances, owing largely to a .342 BABIP. He blew two of his first three save opportunities coming out of the break; one of those blown saves came in an eventual 7-6 win over the Phillies on July 30, hours after the trade deadline passed.

After jumping out to a surprising 40-19 start without the injured Gerrit Cole, the Yankees went just 25-26 in June and July; the swing merely dropped them from two games ahead of the Orioles to half a game back, but without Holmes’ blown saves, they might have enjoyed a bit of breathing room. At the deadline, even as general manager Brian Cashman supplemented the bullpen by adding Mark Leiter Jr. from the Cubs and Enyel De Los Santos from the Padres, Holmes remained Boone’s ninth-inning guy despite increasing scrutiny and pressure. In his role as team captain, Judge expressed his support for Holmes after the Phillies game, which saw the pitcher surrender a one-run lead on two singles, two groundouts, and a wild pitch:

Aaron Judge on Clay Holmes:

“That’s our closer. I don’t know what else to tell you. That’s our guy. He’s been our guy. I want him out there in any situation, bases loaded and no outs or extra innings or bottom nine, top nine — that’s our guy. You can ask anyone in this room if…

Holmes pitched better in August, but still blew two saves, making him just the fifth pitcher over the last decade to reach double digits in that category. By the numbers, which included a 2.67 ERA and 2.48 FIP through August, his season was in line with his 2022 and ’23 campaigns except for a few extra barrels, but the late-inning losses helped keep the Orioles around. As I noted on September 4 while writing about the Yankees’ left field situation, Boone’s avoidance of publicly acknowledging the struggles of both Holmes and Alex Verdugo may have earned loyalty within the Yankees’ clubhouse (and apparently the rest of the organization), but only wound up a frustrated fan base and invited media scrutiny. Things reached a breaking point on September 3, when Holmes served up a walk-off grand slam to the Rangers’ Wyatt Langford. Boone finally addressed the situation the next day: “In the short term, we’ll kind of just get a little creative” with a closer-by-committee arrangement.

He never did have to get too creative. On September 6, he called upon Weaver to close out a 3-0 lead against the Cubs, and the righty did the job, striking out two in the process. “I couldn’t see straight. I was blacked out for the most part. I was on pure adrenaline, but it was a great time,” Weaver said. He went 4-for-4 in save chances, and allowed just one run (unearned) in 11 innings after taking over the role; most impressively, he struck out 24 of 40 hitters in that capacity (60%) while giving up just four hits and three runs. With Holmes in a setup role, things clicked into place for a remade bullpen that included the additions of lefties Hill (who had been released by the White Sox in late June) and Tim Mayza (released by the Blue Jays in early July) and the returns of righties Tommy Kahnle and Ian Hamilton from injuries; the former didn’t debut until May 22 due to a bout of shoulder soreness, while the latter was shelved from May 28 until September 7 due to a lat strain. From September 6 onward, the Yankees bullpen threw 81 innings with a 2.00 ERA, a 3.04 FIP, and a major league-best 32.5% strikeout rate.

Since October rolled around, New York’s relievers have been even better. And now, they’ve helped bring the Yankees within three wins of their first trip to the World Series since 2009.
