Chicago Cubs pitcher Yu Darvish has been scratched from his start Sunday against the Milwaukee Brewers because of tightness in his right forearm.
The Cubs announced that Darvish is expected to make his next scheduled start, which is Saturday against the Brewers in Milwaukee.
"Just like a precautionary thing," Cubs manager Joe Maddon said. "I mean the guy's pitching a lot this year compared to what he did last year. We're really jumping his innings so we want to be a little bit proactive with this thing. We anticipate playing a lot longer than just the rest of this month."
Right-hander Tyler Chatwood will start Sunday's series finale at Wrigley Field.
Darvish, 33, is 5-6 with a 4.25 ERA this season. He has been outstanding since the All-Star break, posting a 2.93 ERA with 72 strikeouts and only three walks in 55 1/3 innings over nine starts.
"It's been varying levels," pitching coach Tommy Hottovy said. "There's some starts where it was bugging him and you'd even see him on the mound kind of do some of the flexing stuff, and then there's other times where he's throwing six innings and feels great, but the next day is when he feels it.
"So when you have that forearm stiffness a day before your start, it's a little more full of hysteria for us to make sure we get this taken care of and then have him ready for the rest of the way."
With expanded rosters Sunday, the Cubs also added infielder Daniel Descalso, outfielder Albert Almora Jr., infielder/outfielder Robel Garcia, right-handers Alec Mills and Duane Underwood Jr., left-hander Brad Wieck, and catcher Taylor Davis.
