New York Mets pitcher David Peterson replaced fellow left-hander Robbie Ray of the San Francisco Giants on the National League roster on Thursday for next Tuesday’s All-Star Game in Atlanta.

Ray, 33, is scheduled to pitch on Sunday against the visiting Los Angeles Dodgers. He is 9-3 this season with a 2.63 ERA, one complete game, 42 walks and 122 strikeouts in 113 innings over 19 starts.

Peterson is a first-time All-Star and will join Mets shortstop Francisco Lindor (starter), first baseman Pete Alonso and closer Edwin Diaz on the NL squad.

The 29-year-old Peterson also pitched on Thursday, but it was not all good news as the Mets fell to the host Baltimore Orioles 3-1 in the first game of a doubleheader. He started and went seven-plus innings, allowing one run (in the eighth) on five hits with no walks and six strikeouts but did not figure in the decision.

Peterson is 6-4 with a 3.06 ERA with one complete-game shutout, 37 walks and 93 strikeouts in 108 innings over 18 starts.

Ray was an All-Star in 2017 for the Arizona Diamondbacks and the American League Cy Young winner in 2021 with the Toronto Blue Jays.

The Giants also will be represented on Tuesday by right-hander Logan Webb and reliever Randy Rodriguez.
