Peterson did not factor into the decision in Friday's 4-3 extra-inning loss to the Giants, allowing two runs on four hits and two walks with four strikeouts over six innings.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.

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.

EDGE Analysis

Peterson was excellent Thursday, holding the O's scoreless through his first seven innings. However, he'd depart after allowing a leadoff single in the eighth to Colton Cowser, who'd ultimately score the tying run after the Mets turned to the bullpen. 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.

Peterson and the Mets won't face the Orioles on Wednesday, as the game was postponed due to rain.

It was a strong bounce-back performance from Peterson, who'd given up 10 runs over 8.2 innings in his previous two starts. The left-hander lowered his ERA to 3.18 with a 1.27 WHIP and 87:37 K:BB over 17 starts (102 innings) this season. Peterson is currently lined up to face the Orioles on the road in his next outing.

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.

EDGE Analysis

Peterson yielded four of his five runs in the second inning, with the Pirates driving in a run 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 since 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.

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.

EDGE Analysis

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.

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.

EDGE Analysis

Peterson has given up three or fewer runs in seven straight outings, turning in six quality starts during that stretch. His 2.23 ERA over that seven-start span has lowered his season mark to 2.60 across 86.2 frames. Peterson's next outing is lined up to be in Philadelphia this weekend.

Peterson (5-2) tallied the win Wednesday against the Nationals after giving up six hits and no walks in nine scoreless innings. He struck out six.

EDGE Analysis

Peterson was brilliant in his first career shutout, keeping Washington off balance with a staggering 13 groundouts while also producing his first scoreless start of the season altogether. 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.
