Hit hard against Cubs Peterson allowed five runs on five hits and two walks while striking out one batter in 1.1 innings Tuesday against the Cubs. He did not factor into the decision.

Impact Peterson continued his stretch of horrendous starts in Tuesday's outing. In nine starts dating back to August 6, Peterson has allowed at least four runs in six of them and has an 8.42 ERA and 1.78 WHIP over that span. The Cubs strung together a pair of runs in the first and another three in the second, forcing Peterson to get the quick hook after throwing just 42 pitches (22 strikes). Manager Carlos Mendoza mentioned afterward that Peterson could play a big role for the remaining five games of the regular season, potentially pitching out of the bullpen. As of now, Peterson is lined up to start Sunday against the Nationals, though that would change if he's used in relief in advance of that game.

AUGUST 20 • ROTOWIRE

Can't capitalize on early lead Peterson pitched 3.1 innings in a no-decision against Atlanta on Wednesday, allowing six runs on five hits and five walks while striking out five batters.

Impact The Mets staked Peterson to a 6-0 lead through two innings, but it didn't take long for the lefty to give all those runs back. He got through three scoreless frames before completely imploding in the fourth, allowing six of the seven batters he faced in that inning to reach base, including four by walk. All six of those hitters came around to score, resulting in a season-worst run total by Peterson. The five free passes also tied a season-high mark, and the 3.1 frames were the fewest Peterson has completed in an outing this year. After giving up two or fewer runs in five consecutive starts from July 3 to Aug. 1, Peterson has now yielded 10 earned runs over 9.1 innings across his past two appearances.

Peterson has worked at least six innings in six straight outings, posting a 2.15 ERA, 1.11 WHIP and 29:11 K:BB over 37.2 innings.

Impact Peterson allowed two runs in the second inning but was otherwise strong, throwing 63 of 97 pitches for strikes and limiting the Giants to just one extra-base hit. The 29-year-old has now delivered five straight quality starts, yielding just five earned runs over 31.2 innings during that stretch. He'll take an impressive 2.83 ERA, 1.24 WHIP and 105:43 K:BB across 127 frames into a home matchup with the Guardians next week.

AUGUST 2 • ROTOWIRE

Delivers six strong frames Peterson (7-4) earned the win Saturday, allowing one run on eight hits and three walks over six innings against the Giants. He struck out four.

Impact The southpaw navigated traffic on the basepaths Saturday but limited the damage to just one run, picking up the win thanks to a two-RBI double by Mark Vientos in the top of the sixth inning. Peterson has consistently gotten the job done this season, logging 121 innings over 20 starts with a 2.83 ERA and 1.25 WHIP. His fastball velocity is down to a career-low 91.7 mph, but he's offset that with a personal best 3.0 BB/9. His 2025 numbers closely mirror his 2024 production, when he posted a 2.90 ERA and 1.29 WHIP across 121 innings in 21 regular-season starts.

No decision despite quality start Peterson did not factor in the decision during Sunday's win over the Reds. He allowed an unearned run on four hits and a walk over six innings while striking out four.

Impact Peterson gave up an unearned run in the first inning but settled in and rolled through five scoreless frames to finish his outing. He forced 12 swinging strikes on 93 total pitches, including six with his slider. Peterson has delivered three straight quality starts in July after coughing up a combined 10 runs in 8.2 innings during his last two June appearances.

Impressive in no-decision Peterson didn't factor into the decision in the opening game of Thursday's doubleheader with the Orioles, allowing one run on five hits over seven innings. He struck out six.

Impact Peterson was excellent Thursday, holding the O's scoreless through his first seven innings.

The 29-year-old Peterson has allowed just two earned runs over 13.2 innings in his last two starts after giving up 10 runs across 8.2 innings in his previous two outings. Overall, the left-hander is 6-4 with a 3.06 ERA, 1.24 WHIP and 93:37 K:BB through 18 starts (109 innings) this season.

Gives up five runs in loss Peterson (5-4) took the loss against the Pirates on Friday, allowing five runs on seven hits and three walks while striking out five across 4.2 innings.

Impact Peterson yielded four of his five runs in the second inning, with the Pirates driving in runs in four consecutive plate appearances, and he didn't get enough run support to escape with the no-decision. Peterson strung together seven quality starts in eight outings after the beginning of May, but he has given up five earned runs in back-to-back appearances, which has inflated his numbers to a 3.30 ERA, 1.28 WHIP and 83:34 K:BB across 95.1 innings. He'll look to get back on track in his next start, which is lined up for next week at home against the Brewers.

Hit hard by Phillies Peterson (5-3) took the loss Sunday against Philadelphia, allowing five runs on six hits and three walks over four innings. He struck out four.

Impact Peterson hadn't allowed a home run in his past six starts, but he yielded a pair of round trippers Sunday. Both homers came in the fourth frame on a solo shot from Kyle Schwarber and a three-run homer from Edmundo Sosa. Peterson's loss was his first since May 6. On the year, Peterson owns a 2.98 ERA to go along with a 78:31 K:BB across 90.2 innings.

JUNE 23 • ROTOWIRE

Delivers quality start Peterson did not factor in the decision during Tuesday's loss against Atlanta. He allowed three runs on five hits and three walks over seven-plus innings while striking out three.

Impact Peterson gave up one run through seven frames and came out for the eighth inning.

It was also just the fourth time this year that the 29-year-old left-hander didn't lend a free pass, and he's now hurled at least six frames in six of his last seven outings. Peterson sports a 2.49 ERA, 1.19 WHIP and 71:25 K:BB across 79.2 innings, and he's scheduled to toe the slab in a tough road matchup against Atlanta next week.

Allows three runs in no-decision Peterson didn't factor into the decision Thursday after allowing three runs on seven hits and two walks while striking out six in seven innings of work during a 6-5 loss to the Dod...

Impact Peterson continued his hot recent stretch this season, tossing seven more quality innings against one of the league's more dangerous lineups. He's started two games against the Dodgers now and they have been the two longest starts of the southpaw's season. The 29-year-old has thrown at least six innings in five of his last six starts, and hasn't allowed more than three earned runs in any of them, sporting a 2.58 ERA over that timeframe. Peterson is next slated to start at home against the Nationals next Wednesday.

JUNE 6 • ROTOWIRE

Earns fourth win Peterson (4-2) earned the win against the Rockies on Friday, allowing one run on five hits and one walk while striking out five across 5.2 innings.

Impact Peterson faced the minimum number of batters in two of the first five innings of Friday's game. He was brought back out for the sixth, but he was lifted after yielding an RBI double to Ryan McMahon. Peterson was one out shy from what would have been his fifth-straight quality start (and seventh of the season), but he received enough run support to come away with the win. The 29-year-old southpaw hasn't given up more than three earned runs in any of his 11 starts this season, and his 2.69 ERA (across 63.2 innings) is sixth best among qualified starters in the National League this season. He is slated to make his next start on the road against the Dodgers next week.

MAY 31 • ROTOWIRE

Shines in win over Dodgers Peterson (3-2) earned the victory over the Dodgers on Saturday, allowing two runs on five hits and two walks while striking out seven batters over 7.2 innings.

Impact Peterson fell behind 2-0 in the second inning but didn't give up another run for the remainder of his outing. The southpaw completed a season-high 7.2 frames (in fact, this was the first time all year he's pitched more than six innings) and recorded his fourth straight quality start. Peterson's past two outings have been particularly impressive given the quality of opponent -- he's yielded just three earned runs over 13.2 frames versus the Yankees and Dodgers. The veteran hurler has been a key part of the Mets' rotation this year, posting a 2.79 ERA, 1.28 WHIP and 54:22 K:BB through 58 innings. Peterson's next start is projected to be much less intimidating on paper than his past two, as he's lined up to face the Rockies at home next weekend.
