"There was a stretch there where I kept throwing the ball and the ball was cutting on me," Danks said. "I was trying to throw the ball down and away to a righty and it was cutting back over the plate.
"It's just mechanical. It's just part of the process."
Danks worked on correcting that flaw Thursday in Cleveland, in preparation for Saturday night's start against Detroit.
"That's what we've come up with," Danks said. "It's not something that's new. But definitely something we are going to keep working on."
