Peralta built six scoreless innings around a heavier fastball mix

More fastballs, with a separate job for the changeup

The primary comparison contains 2,959 physical pitches from 32 regular-season starts for the Mets and Rays, March 26 through September 25. The four-seamer made up 53.0% of that sample. Its Game 2 share was 71.7%, an increase of 18.7 percentage points. The full season denominator retains pitch types he did not throw in this game.

His 10 Tampa Bay regular-season starts offer a narrower check: 866 pitches from August 4 through September 25. Four-seamers accounted for 52.1% and averaged 94.8 mph. The larger Game 2 fastball allocation was present relative to both the full season and his Rays-only sample.

The opponent’s handedness affects that comparison. Twenty of his 25 plate appearances came against batters hitting left-handed. Even within those matchups, he threw four-seamers on 62 of 89 pitches, or 69.7%, compared with 51.4% against left-handed hitters in the regular-season sample. The overall increase was therefore not solely a consequence of facing more left-handed hitters.

His four-seamer averaged 96.9 mph, compared with 94.3 across the regular season. That faster postseason speed was already present in his October 5 start against the Yankees, when he averaged 96.8 mph with 43 four-seamers among 66 pitches. In Game 2 against Cleveland, the pitch supplied nine called strikes and 10 recorded whiffs in 45 swing attempts.

Nathaniel Lowe’s fourth-inning strikeout showed that work directly. After two fastballs for balls, Lowe took a fastball for a strike and foul-tipped another. Peralta finished him with a 97.3-mph four-seamer above Lowe’s recorded zone. That five-pitch at-bat also shows why the final pitch alone cannot explain the out: the preceding taken strike and foul tip recovered a 2–0 count.

The changeup accounted for 18 pitches, or 18.2%, compared with 23.4% in the regular season. It generated four recorded whiffs in eight swings and ended the second-inning strikeouts of Halpin and Brayan Rocchio, then Halpin’s strikeout in the sixth. Ten curveballs supplied three called strikes and one whiff, adding another route to a strike without accounting for a strikeout finish.

Across the full outing, Peralta recorded 15 whiffs in 56 swing attempts, a 26.8% rate. The season sample had 371 in 1,419 attempts, or 26.1%. Heavier and faster four-seamers did not produce a broad rise in aggregate whiffs. The common tracking definition includes six caught foul tips in Game 2, which involved bat contact. Nine other attempts were actual swing-and-miss strikes.

A scoreless line still included escapes and hard contact

The changeup’s effective finishes came when Cleveland offered at it. All ten that were taken became balls, and none became a called strike. Bazzana also singled off one in the second inning. Its four whiffs in eight swings therefore coexisted with pitches that hitters declined to chase and a hit on contact.

Both walks went to Chase DeLauter. The third-inning confrontation cost eight pitches after Peralta reached a 1–2 count. In the fifth, DeLauter reached 0–2 on a fastball miss and foul, then took four balls after another foul. José Ramírez had singled and stole second during that at-bat, leaving two runners aboard before Jo Adell lined out to end the inning.

Austin Hedges’ second-inning hit by pitch was a separate baserunner from those two walks. Tampa Bay challenged the ruling, and it was upheld. Together with the wild pitch during Halpin’s at-bat, it shows that keeping Cleveland scoreless required more than simply avoiding hard contact or allowing no walks.

Contact nevertheless helps explain the result. The 16 measured balls in play averaged 84.0 mph. His regular-season average was 87.0 across 502 measured contacts, with one additional ball in play lacking an exit-speed measurement. Three of Cleveland’s contacts reached 95 mph, Statcast’s hard-hit threshold. The Guardians found four hits without consistently striking the ball hard, including Steven Kwan’s 57.7-mph single to begin the game.

The clearest warning against equating an out with harmless contact came in the sixth. Bazzana hit a 96.8-mph fastball at 102.4 mph, with a recorded 401-foot distance, but Jonny DeLuca caught it in center. That was one of the three hard-hit balls, and it remained an out in the pitching line. The result includes where the ball went and what the defense did, alongside the quality of the pitch.

Peralta used only seven pitches in the first inning, then 25 in the second. His workload reached 85 after five innings, and Halpin’s nine-pitch final plate appearance took it to 99. Four-seam velocity stayed within a narrow band of inning averages, from 96.5 to 97.2 mph; the sixth averaged 96.7 across nine fastballs.

The last out again came on a changeup, this time an 89.0-mph pitch that Halpin foul-tipped for strike three after three full-count fouls. Peralta left with a 3–0 lead and no runners for the bullpen to inherit. The full record supports an outing built around increased fastball use, with changeups supplying important finishes and favorable contact outcomes keeping his six innings scoreless. A subsequent matchup can test whether he retains that larger fastball share while limiting walks and the harder contact that could change the result.
