David Peterson with ice in his veins 🥶 After Peterson pitched a complete game shutout against the Nationals, he lowered his season ERA to 2.49! Peterson has emerged as one of the best lefties in all of baseball, given his workhorse pedigree and his sure-fire ability to pitch deep into ballgames every fifth day. DP is on another level right now! #Mets #LFGM #DavidPeterson
