CLEVELAND -- Michael Chavis played through the pain for as long as he could.
On Monday, the Boston Red Sox rookie finally gave in.
Boston placed the versatile Chavis on the 10-day injured list with a sprained left shoulder he sustained recently while trying to make a diving catch.
One of the American League's top first-year players, Chavis has 18 homers and 58 RBIs, second-most to New York Mets slugger Pete Alonso among rookies. But he has been in a slump, batting .156 (5-for-32) in his past 11 games, and the shoulder injury explains Chavis' recent slide.
"It stinks," Chavis said, adding that the pain is most severe when he swings a bat. "I want to be out there and help the team, but if I can't do my part, it's tough."
Red Sox manager Alex Cora didn't want to put a timetable on when Chavis will return. He won't swing a bat for five or six days.
"It makes sense for him to get healthy," Cora said. "He tried to play through it. It's one of those things we have to manage now."
The Red Sox also recalled right-hander Travis Lakins and infielder Marco Hernandez from Triple-A Pawtucket.
The moves were announced before the Red Sox opened a three-game series at Progressive Field. The defending World Series champions have lost 11 of 14 and are 16.5 games behind the first-place New York Yankees in the AL East and 7.5 back for a wild-card spot.
Chavis' home run and RBI totals are the most by a Red Sox rookie since Ellis Burks hit 20 home runs with 59 RBIs in 1987. Chavis played first base (49 games), second (45) and third (five).
Chavis, 24, said it's important to stay upbeat while he's out.
"If you get away from something, you can clear your mind," the 2014 first-round pick said. "I'm a positive person, so I'm trying to find a positive in all this. That's one of the things I'm looking at."
