David Ortiz left Thursday’s game after a check swing in the ninth inning. He had spasms in the middle of his back and is day-to-day.
The Red Sox lost to the Blue Jays, 8-0, in Toronto.
Ortiz said he felt “a little pop” in his back in his final at-bat on Wednesday night but felt fine when he arrived at Rogers Centre for the final game of the series. That changed when he tried to hold up his swing while facing Rob Rasmussen.
“I made like a rough move on that pitch, like tried to go and stop. It pulled me a little bit more today,” Ortiz said. “Hopefully it’s not anything serious. We’ll see how it feels tomorrow.”
Jonny Gomes completed Ortiz’s at-bat, flying out to left field to end the game.
Ortiz left the park with a pain-relieving patch on his back. For the desperate Red Sox, even just a few days without their most productive hitter would be damaging. They start a three-game series against Tampa Bay on Friday night.
