Greinke (oblique) will throw 80 pitches at Triple-A Reno on Wednesday, Jack Magruder of Fanragsports.com reports.
Greinke has not felt pain when throwing or swinging, so an Aug. 9 return still seems entirely possible. This will be the most he's thrown in a game since going on his rehab assignment, so he'll look to get back on track, as he'd been quickly improving from his rough start to the season before being injured.
