David Peterson twirled six innings of one-run ball against the Phillies on Wednesday night as the Mets won 5-1. The team that’s given him fits during his brief major league career was silent except for a Jean Segura home run in the fifth inning.

Facing Philadelphia for the second time in two starts, Peterson upped his velocity and struck out 10, tying his career-high. He no-hit the Phils through 4 1/3 innings to earn the win. Peterson is the first Mets left-hander since Chris Capuano in 2011 to strike out 10 without issuing a walk.

He set the top of the lineup down in order to open the game. Andrew McCutchen tapped a fastball toward third base, easily corralled by Luis Guillorme. Rhys Hoskins and Bryce Harper, who combined to go 5-for-6 with three doubles and a home run against Peterson last Wednesday, struck out to end the inning. They finished 1-for-6 with three strikeouts against Peterson on Wednesday night.

Peterson’s lone trouble his first go through the lineup was a rocket hit 108.7 miles per hour off the bat of J.T. Realmuto. It bounced out of Dominic Smith‘s glove in left field and ruled an error. Philadelphia had a runner on second to start the second but Peterson retired Alec Bohm, Segura, and Ronald Torreyes in order to end the inning.

Peterson struck out six of his first nine batters faced.

He cruised through the third and fourth innings before noted Mets killer Segura recorded their first hit of the day. A 385 foot home run to left field. Peterson recovered to strike out Torreyes on three pitches as Roman Quinn flew out.

He finished the sixth allowing just his second hit, a single from Hoskins with two outs. With a runner on, Harper flew out on the first pitch he saw.

At 80 pitches, Peterson’s night was done. The Mets had runners on the corners with two outs in the bottom of the sixth. Up 2-1, manager Luis Rojas opted for a pinch hitter.

Encouraging for Peterson and the Mets was his velocity. His sinker was averaged 93.1 mph (up from 91.8) and his fastball averaged 93.8 (up from 92.1). He topped out at 95.3 mph, an encouraging sign off a full weeks rest.

He routinely fooled Phillies hitters posting an elite 35 CSW% (called strikes +whiffs percentage). His slider consistently found the plate, resulting in nine called strikes on 20 thrown. His one whiff off the slider struck out Harper in the first.

The 25-year-old needed to rebound after allowing six runs across four innings to the Phillies on April 7. The lanky lefty fits into the rotation for now but could find himself battling for the last spot when Carlos Carrasco and Noah Syndergaard return.

Peterson continues to impress despite not throwing overwhelming stuff and now sits 4-o at Citi Field and 7-3 for his major league career.

His box score numbers are expected to regress from last year. In 2020, he outperformed his 4.39 xERA and 5.11 xFIP to a tune of a 3.44 ERA and 4.52 FIP over 49.2 innings. The second question for Peterson is if his arm will hold up. The most innings he’s thrown is 116 at Double-A in 2019. A shortened season last year doesn’t help.

For now, the Mets are just focused on his next start. What would line up to be Tuesday at the Chicago Cubs, might be in jeopardy as rain threatens the team today and snow is in the forecast for their series in Colorado. Expect him to pitch one of the three against Chicago next week.
