Mets manager Carlos Mendoza was ejected from Saturday's game against the Pittsburgh Pirates in the fourth inning for arguing balls and strikes with home plate umpire Roberto Ortiz.

Mendoza started going off on Ortiz from the dugout during the top of the fourth inning when a pitch thrown to Mark Vientos on a 3-0 count appeared to be a ball. Vientos prepared to walk to first, but Ortiz called the pitch a strike. Mendoza was clearly upset about the call.

PITTSBURGH — Roberto Ortiz’s strike zone was irking manager Carlos Mendoza even before he got ejected in the bottom of the fourth inning Saturday. The Mets manager had seen enough after Brandon Waddell delivered a 1-0 pitch to Adam Frazier, the second Pirates batter in the frame.
