Peterson gave up two hits and three walks over five scoreless innings in Wednesday's Grapefruit League game against Houston. He struck out four.
Peterson continued a stingy spring that has seen him post a 0.57 ERA and 12:7 K:BB through 15.2 innings. The 29-year-old lefty has a rotation spot locked up due to Sean Manaea (oblique) and Frankie Montas (lat) being set to begin the season on the IL, and Peterson is expected to make his first start of 2025 on March 31 in Miami.
Peterson struck out five over three scoreless innings in Monday's Grapefruit League game against the Marlins, giving up one hit without walking a batter.
The southpaw took over for Kodai Senga to begin the third inning and fired 25 of 37 pitches for strikes before hitting the showers. Peterson is coming off the best year of his big-league career in 2024, posting a 2.90 ERA, 1.29 WHIP and 101:46 K:BB over a career-high 121 regular-season innings during the regular season before working another six innings in the playoffs, and the Mets are counting on the 29-year-old to help solidify a rotation that will be missing Sean Manaea (oblique) and Frankie Montas (lat) to begin 2025.
Mets' David Peterson: Agrees to deal with New York

The Mets and Peterson avoided arbitration by agreeing to a one-year contract Thursday.
Peterson will be able to skip a hearing in what was his second year of arbitration eligibility. The southpaw's strikeout rate dipped to 19.8 percent in 2024, but he finished with a 2.90 ERA over 21 regular-season starts and will open 2025 in the Mets' rotation.
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.
