The Mets called up Pintaro from Triple-A Syracuse on Friday.
With Cionel Perez (forearm) hitting the 15-day injured list, the Mets recalled Pintaro to take his place in the bullpen. Pintaro appeared in five games earlier this season, recording a 5.11 ERA, 0.73 WHIP and 12:3 K:BB through 12.1 innings.
