"He wanted to stay in, but it just didn't feel right to me in my gut," Pirates manager Clint Hurdle said. "I didn't think the risk was worth the reward."
Batting with two outs and nobody on base in the fourth inning, with the Indians up 3-0, Marte swung and missed at the first two pitches he saw from Cleveland starter Danny Salazar. After the second swing, Marte stepped out of the batter's box, and Hurdle and a team trainer came out to check on him.
Marte returned to the batter's box, weakly fouled off a pitch and took another for a ball. Hurdle re-emerged from the dugout to talk to Marte, who headed into the dugout and left the game.
As he was leaving the ballpark Sunday afternoon, Marte indicated that he felt some pain in the muscles on the left side of his torso. He said he's dealt with a similar injury before, specifically recalling an instance where it flared up two years ago.
Marte fought to stay in the game at first but said he agreed with Hurdle's assessment that it wasn't worth the risk.
"There's been some situations where it pops up, then it goes away," Hurdle said. "It didn't look like it was going away, so I just made a call and we got him out."
Gregory Polanco, initially given the day off, finished the at-bat by grounding out. Polanco remained in the game in Marte's spot, batting fourth and playing left field.
