Peterson will start Game 5 of the NLCS against the Dodgers on Friday, Pat Ragazzo of SI.com reports.
Peterson last pitched in Game 1 of the NLCS, though he's appeared exclusively out of the bullpen throughout the playoffs. He has yet to complete more than three innings in any of his six postseason appearances, and Kodai Senga sounds likely to also play a significant part of the Mets' plans Friday.
Peterson (10-3) earned the win Sunday, allowing one hit and three walks over seven scoreless innings against the Brewers. He struck out eight.
Peterson saved his best performance for when the Mets needed it most, allowing just a first-inning infield single to Jackson Chourio en route to his second scoreless effort of the year. The eight strikeouts matched his second-highest total of the season, while he dropped his ERA to an impressive 2.90 over 21 starts spanning 121 innings. The Mets still have work to do to make it to the postseason, but should they advance following Monday's doubleheader with Atlanta, Peterson would be required to work on short rest if he were to make an appearance in the Wild Card Round.
Peterson won't pitch as scheduled Wednesday against Atlanta after the game was postponed due to inclement weather, Joel Sherman of the New York Post reports.
Hurricane Helene has caused MLB to postpone both Wednesday's and Thursday's games, which will be made up via a doubleheader Monday if the results of those contests could affect playoff positioning. New York is currently a half-game up on Arizona for the final NL wild-card spot, with Atlanta being just a half-game back of the Diamondbacks. The Mets haven't disclosed how they plan to adjust their rotation following the pair of postponements, but Peterson could pitch this weekend in Milwaukee.
Peterson (9-3) took the loss Friday against Philadelphia, allowing five runs (four earned) on eight hits and no walks over 3.2 innings. He struck out four.
The southpaw failed to reach the fifth inning for the first time this season, as he allowed a run in every frame during this 64-pitch performance. This is now the second time in three starts Peterson has yielded four earned runs after previously stringing together seven consecutive outings allowing two or fewer runs. The 29-year-old's ERA has risen to 3.08 across 114 total innings to go with a 1.33 WHIP and 93:43 K:BB. Peterson will look to bounce back in his next start, currently scheduled to be one with tremendous playoff implications at Atlanta next week.
Peterson didn't factor into the decision Sunday against Philadelphia, allowing one run on four hits and a walk across 7.2 innings. He struck out six.
Peterson and Cristopher Sanchez were locked into a pitchers' duel Sunday, but neither was credited with the victory. Peterson yielded five runs (four earned) in his previous start after yielding two or fewer earned runs in seven consecutive outings. Since the start of August, Peterson is 4-1 with a 2.22 ERA and a 46:17 K:BB across 56.2 innings.
Peterson (9-2) took the loss Tuesday, giving up five runs (four earned) on eight hits and two walks over 4.1 innings as the Mets were downed 6-2 by the Blue Jays. He struck out two.
The southpaw was saddled with his first loss since July 28 as he struggled with his command. While Peterson tossed a respectable 51 of 76 pitches for strikes, he uncorked two wild pitches and plunked a batter, and he gave up some hard contact when he was in the strike zone. He saw his quality start streak end at five, and since the beginning of August he still sports a 2.39 ERA, 1.22 WHIP and 40:16 K:BB through 49 innings, Peterson will look to bounce back in his next outing, which lines up to come at home early next week against the Nationals.
