What a moment for Peterson. He was met by a roaring ovation from the Citi Field faithful on his way to the mound just before finishing off the first complete game shutout of his career. An incredibly rare feat in this day and age, Peterson was very efficient on his way to this gem. He’d thrown just 32 pitches after the first three innings and forced 18 total ground balls on 25 balls in play. This was also the third time in four starts he’s completed at least seven innings and he now has a sterling 2.49 ERA, which is the fourth-lowest in the National League. He’s heading into a huge two-start week against both the Braves and Phillies on the road with some serious momentum.

Peterson seemed to be cruising to a win before this Mets bullpen allowed three runs in the eighth inning to cough up the game. The left-hander struck out six on the day while walking two and posting a 29 percent whiff rate and 30 percent CSW. He got plenty of whiffs on his slider, and the four-seamer controlled the zone for much of the day. Peterson has been great this year, with a 2.80 ERA so far. He’s in a good spot against the Nationals next week.

While Peterson wasn’t his sharpest, he still managed to work his way to a solid final line. Falling one out short of the quality start is frustrating, but the Rockies were rallying against him in the sixth innings and he was fortunate that Huascar Brazobán stranded runners on second and third base. Francisco Lindor also made a tremendous leaping grab with the bases loaded and two outs in the third to save two runs. He just didn’t quite have the usual strong command of his slider against right-handed batters which limited his swings-and-misses. He’ll have to be sharper in his next scheduled start against the Dodgers.
