The Mets called Peterson up from Triple-A Syracuse in advance of his start in the second game of Saturday's doubleheader in Philadelphia, Mike Puma of the New York Post reports.

EDGE Analysis

Peterson has been quite effective for the Mets this season, striking out 27.2 percent of opposing batters en route to a 3.30 ERA in 14 starts and four relief appearances. He hasn't been needed in the rotation since Jacob deGrom returned from a shoulder injury, but he remains the top name the Mets will turn to whenever they need a spot start.
