"He doesn't even know when he did it," said Indians skipper Terry Francona. "He thought the last time he might have slept on it wrong, because it didn't hurt last night and it was a little tender this morning."
Kipnis is batting .125 (4-for-32) in eight games this season. With White Sox southpaw Chris Sale on the mound, Francona had no problem resting his left-handed-hitting second baseman. Sale, 17-8 with a 3.05 ERA last season, has limited lefties to only one hit in 15 at-bats (.067 average) in two outings this year.
"[It's] just a little sore and I think we would like to keep it that way," Francona said. "Taking into consideration who we're facing, it just makes sense. Let this thing hopefully be a one-day thing. That's my thought."
