The Cubs placed right-hander Jake Arrieta on unconditional release waivers Thursday, one day after he gave up seven runs and eight hits in the first inning of a 10-0 loss to the Milwaukee Brewers.

"He was struggling," president of baseball operations Jed Hoyer said. "Not getting deep into starts. We've been patient and tried to get through it and hopefully he [would] come out the other side and pitch better. We weren't there."
