The Red Sox placed left-hander Chris Sale on the injured list with shoulder inflammation on Friday, another setback for the seven-time All-Star as he attempts to re-establish himself as a reliable member of the rotation.

"It's just kind of a gut punch," Sale told reporters before Friday night's game against the Tampa Bay Rays. "I hate feeling like this. I started having fun playing baseball again. And now, back to not having fun. That sucks."
