Peterson

Sammon makes it clear that the Mets aren’t actively shopping Peterson, but they would move the 2025 All-Star if it helps them fill needs elsewhere, likely to acquire an outfielder to replace Brandon Nimmo. Since coming back from hip surgery after the 2023 season, Peterson has a 3.67 ERA in just under 300 innings and is likely to earn $7.6 million in arbitration in 2026, so he would be extremely affordable for whatever team wanted to acquire him. That also means the Mets would “hold a high asking price” in any deal.

Peterson surrendered two runs in the first on a single, a walk and a fly to right that Juan Soto turned into a double. The second started with a walk and three hits that surrounded a sac bunt, and the Mets pulled him at that point. He probably would have gotten a chance to recover if this didn’t make for five subpar outings in a row, but the team has obviously lost some faith in him. He’s not nearly so far gone that he should be ruled out going forward, but it’ll be fascinating to see the Mets’ pitching decisions from here on in. While Peterson is due to start Sunday against the Marlins, it’s anyone’s guess whether that will happen.

Peterson’s disastrous second half continued here. He allowed runs in each of the first two innings, but seemed to settle in reasonably well afterwards. That is, until a mammoth grand slam from Manny Machado in the fifth inning on a 3-2 curveball that caught far too much of the plate. It turned Peterson’s line from palatable to awful and the circumstances by which he got there were even more frustrating. He hit Jake Cronenworth with two strikes, walked Fernando Tatis Jr. after getting ahead of him 1-2, and then Luis Arraez dropped down a bunt single to set the stage for Machado. Peterson now has an ugly 4.86 ER since August 1st and is scheduled for a tough meeting with the Cubs up next.

On the plus side for fantasy managers, Peterson racked up eight strikeouts on the night while issuing only one base on balls. After being staked to an early 4-0 lead, Peterson kept the Phillies’ offense at bay until Otto Kemp’s two-run blast in the fourth inning. They added another on an RBI double by Bryce Harper in the fifth inning. The 30-year-old southpaw got a whopping 19 swings and misses on 86 pitches in the ballgame — 10 of them on his curveball — while posting a strong CSW of 35 percent. He’ll attempt to get back in the win column as he totes a 3.77 ERA, 1.32 WHIP and a 148/60 K/BB ratio (162 1/3 innings) into Thursday’s tilt against the Padres.

Peterson cruised through the first two innings as his lineup built up a big lead. Yet, he ran into trouble in both the third and fourth as the Reds put four runs on the board. Then it felt like he got over the hump and was ready to pitch deeply into this game when he began the sixth inning with just 70 pitches. Somehow, it took him 21 pitches to face three batters and he only retired one before being pulled. He didn’t have good feel for any of his pitches really as too many sinkers bled over the heart of the plate and got hammered while his breaking balls were often noncompetitive. This was his fourth clunker in his last six starts which has brought a 2.83 ERA up to a 3.72 ERA. He’ll have a stiff test next week as the Mets head to Philadelphia to take on the Phillies.

Peterson struggled out of the gate against the Marlins, giving up five runs on five hits and a walk to open the game in the first inning. After a clean second inning two walks and three hits brought another pair of runs in to score before Peterson was relieved with no outs and the bases loaded. The 29-year-old left-hander will look for better results when he takes a 3.55 ERA, 1.31 WHIP, and a 136/58 K/BB ratio across 152 innings into a start against the Reds in Cincinnati next Saturday.

Peterson had a shutout going until the sixth, when he gave up a two-run single to Sean Murphy after carelessly walking Nacho Alvarez Jr. That ended his day at 98 pitches. He had 20 whiffs, 10 of them coming on the 22 sliders he threw, and not one of his 40 breaking balls produced a hard-hit ball. This would have been a gem if he didn’t lose the strike zone at the end. He’ll face the Marlins next.

Peterson allowed just four hits in a big rebound outing after giving up six runs to the Braves last time out and four runs to the Guardians before that. It’s his first 10-strikeout game of the year. He’s had exactly one of those every season since making his major league debut in 2020. He figures to face the Braves again on Sunday.

Spotted a six-run lead, Peterson could not escape a fourth inning that spun out of control after he walked the eighth and ninth batters in the Braves’ order. He missed to his arm side all game long and was visibly frustrated on the mound as he let the Mets’ big lead evaporate, a trend that’s become all too normal lately. He’s scheduled to make a two-start week next with road games against the Nationals and Braves again.

Peterson had allowed two runs or fewer in five straight starts. He generated 15 missed swings and had a 33% CSW today, but he gave up homers to David Fry and Angel Martínez. They were just the eighth and ninth homers he’s allowed in 133 innings this season. He’d given up just two previously in 11 starts at Citi Field. Peterson will face the Braves next week.
