Peterson (2-1) got the win over the Diamondbacks on Tuesday, allowing one run on five hits while striking out two over five innings. He did not walk a batter.
Peterson got through four scoreless before the Diamondbacks finally pushed across a run with two singles and a double in the fifth. He did not come back out for the sixth despite being at 85 pitches and the Mets holding an 8-1 lead and hasn't reached six innings in any of his last three starts. Peterson's had two outings with nine strikeouts already this season but has combined to punch out only four in his last two starts. On a positive note, he has one walk over his last four outings and hasn't allowed more than three runs in a start thus far. He'll aim to beat the Diamondbacks twice in the span of a week when the Mets travel to face them Monday.

Mets' David Peterson: No-decision Wednesday
Rotowire
Peterson didn't factor into the decision Wednesday against the Phillies, allowing two runs on eight hits and a walk across 5.1 innings. He struck out two.
The eight hits given up by Peterson marked a season high, though none went for extra bases, allowing the left-hander to mitigate the damage. Peterson's now surrendered at least seven hits in his last three outings, though he's issued just one walk in that span (16.2 innings). His ERA sits at 3.29 on the year with a 1.43 WHIP and 28:9 K:BB across five starts (27.1 innings). Peterson is currently scheduled to face the Diamondbacks at home in his next outing.

Mets' David Peterson: Matches season high with nine Ks
Rotowire
Peterson didn't factor into the decision Friday against the Cardinals after allowing three runs on seven hits and no walks in 5.1 innings. He struck out nine.
The nine punchouts matched a season high, and just one of Peterson's nine hits allowed went for extra bases. The left-hander has upped his strikeout rate a bit to begin the season, fanning 26 over 22 innings, and he should maintain a rotation spot as long as Sean Manaea (oblique), Frankie Montas (lat) and Paul Blackburn (knee) are all on the shelf. Peterson has a serviceable 3.27 ERA and 1.36 WHIP across four starts this season, but he's in line for a difficult assignment in next week's scheduled outing against the Phillies.

Mets' David Peterson: Takes loss despite quality start
Rotowire
Peterson (1-1) took the loss Saturday against the Athletics, allowing two runs on seven hits while striking out five across six innings. He did not issue a walk.
Peterson started out strong by retiring eight of the first nine batters he faced, but he ran into trouble in the fourth inning when he gave up four hits and two runs. He was able to recover to get through the next two innings without issue and finished his outing tossing 89 pitches (66 strikes), with 19 first-pitch strikes and eight whiffs, though the 29-year-old southpaw did not receive enough run support from his teammates to avoid the loss. Peterson has had a strong start to the season, registering a 2.70 ERA, 1.38 WHIP and 17:8 K:BB across 16.2 innings. He's tentatively slated to face off against the Cardinals at home next week.

Mets' David Peterson: In clear to start Saturday
Rotowire
Peterson (illness) is listed as the Mets' probable starting pitcher for Saturday's game against the Athletics in Sacramento.
Mets manager Carlos Mendoza acknowledged after Peterson's latest start Sunday against Toronto that the southpaw was dealing with some nauseousness, but Peterson never appeared to be at any major risk of missing his next turn through the rotation. Despite being less than 100 percent and issuing five walks while taking a no-decision against Toronto, Peterson limited the Blue Jays to one run over 4.2 innings, lowering his ERA to 2.53 in the process.

Mets' David Peterson: Nausea prompts early exit
Rotowire
Peterson was removed from Sunday's start against the Blue Jays in the fifth inning due to nausea and blurred vision, Anthony DiComo of MLB.com reports.
The left-hander was in clear discomfort during the fifth inning and was finally pulled with two outs after he had two walks and a hit-by-pitch to three straight batters. Prior to that inning, Peterson was pitching well and still allowed just one run across his 4.2 frames. Peterson should be OK for his next turn through the rotation versus the A's next weekend.

Mets' David Peterson: Pitches through apparent injury Sunday
Rotowire
Peterson appeared to be pitching through an unspecified injury during his start in Sunday's win over the Blue Jays, Anthony DiComo of MLB.com reports. He took a no-decision in the Mets' 2-1 win after giving up one earned run on three hits and five walks while striking out three.
Peterson kept the Blue Jays off the board over the first four innings but seemed to be in discomfort while laboring through the top of the fifth. He was visited on the mound on multiple occasions during the inning and issued a pair of walks and also hit a batter to load the bases before manager Carlos Mendoza pulled him from the game. Max Kranick came on from the bullpen and recorded the final out of the inning to strand three runners and allow the Mets to maintain a one-run lead that held up as the difference, but Peterson didn't qualify for the win after narrowly missing out on the five-inning threshold. Mendoza should provide more details regarding Peterson's situation after the game, but for now, the left-hander tentatively lines up to make his next turn through the rotation next weekend versus the Athletics in Sacramento.

Mets' David Peterson: Settles in Monday
Rotowire
Peterson (1-0) picked up the win after giving up two runs on five hits and three walks in six innings Monday against Miami. He struck out nine.
After allowing a solo home run to Otto Lopez in the first inning, Peterson settled in thereafter while receiving plenty of run support. Eric Wagaman did tag Peterson for another solo shot in the sixth frame, but it was an otherwise strong season debut overall for the southpaw. Peterson's next start is tentatively scheduled to come this weekend at home against Toronto.

Mets' David Peterson: Blanks 'Stros on Wednesday
Rotowire
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.

Mets' David Peterson: Dominant in Monday's outing
Rotowire
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
Rotowire
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.

Mets' David Peterson: Drawing Game 5 start
Rotowire
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.

Mets' David Peterson: Tosses gem to earn 10th win
Rotowire
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.

Mets' David Peterson: New York-Atlanta postponed
Rotowire
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.

Mets' David Peterson: Stumbles against Phillies
Rotowire
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.

Mets' David Peterson: Tough night in Toronto
Rotowire
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.

Peterson didn't factor into the decision Thursday against Arizona, allowing two runs on seven hits and two walks over seven innings. He struck out four.
Peterson has now gone seven innings in three straight starts while delivering quality starts in five of his last six outings -- he's pitched to an impressive 1.86 ERA in that span (38.2 innings). Overall, the left-hander is 8-1 with a 2.83 ERA, 1.32 WHIP and 70:39 K:BB across 92.1 innings this season. Peterson will look to keep rolling in his next start, currently scheduled for next week at home versus the Red Sox.

Mets' David Peterson: Walks four in win
Rotowire
Peterson (7-1) allowed an unearned run on three hits and four walks while striking out four over 6.1 innings to earn the win Wednesday over the Athletics.
This marked Peterson's sixth time going at least six innings this season, and it was one of his strongest performances this year. The one concern that remains is his high walk rate -- he's issued at least three walks in five of his last six starts and has a 4.3 BB/9 this season. Peterson has managed to post a 3.04 ERA despite a 1.39 WHIP and 56:34 K:BB through 71 innings over 13 starts on the year. He's projected for a tougher home start versus the Orioles early next week.

Mets' David Peterson: Notches fifth win
Rotowire
Peterson (5-0) picked up the win Monday against Miami, allowing two earned runs on six hits and four walks in five innings. He struck out four.
Peterson wasn't flashy, but he allowed two earned runs or fewer in a sixth consecutive start, logging a 2.53 ERA, 1.47 WHIP and a 30:18 K:BB in 32 innings during that stretch. The southpaw's poor 36:23 K:BB in 48.2 innings limits his upside, but he has been solid for the Mets this season with a 3.14 ERA. He will look to keep rolling his next time out, a start which is tentatively scheduled for this weekend against Atlanta.
