Peterson will start Sunday's game against the Phillies, Laura Albanese of Newsday reports.
Peterson has surrendered nine earned runs in just 6.2 innings across his last two outings, but the Mets will trust him to start on the mound during Sunday's series finale. The Phillies have turned in just a .670 OPS across their last 10 contests, but the 30-year-old southpaw's recent performance puts a low ceiling on his fantasy appeal.
