6/30 Extra bases
Marlon Byrd will play for Triple-A Iowa Thursday through Saturday, and was expected to join the Cubs on Sunday for the next road trip. Iowa had Wednesday off and opens a series against New Orleans on Thursday. Byrd is rehabbing from facial fractures suffered when he was hit by a pitch May 21. He’s hit a three-run homer so far for Iowa.
* Andrew Cashner was examined by Cubs orthopedic specialist Stephen Gryzlo on Thursday. If the right-hander gets the go-ahead, he could begin a throwing program Friday. He’s been rehabbing in Mesa, Ariz.
* Kerry Wood will be activated from the DL on Friday, just in time for the Cubs series vs. the White Sox. Wood tested the blister on his right index finger by throwing 15 pitches in a live BP session on Wednesday.
