• Third baseman Ian Stewart, who received a cortisone shot last week in his left wrist, is not making progress in his rehab.

"The shots and everything don't seem to be making a difference," Cubs manager Dale Sveum said. "I don't know what we'll end up doing with that. There's definitely no progress going on."

Stewart has been sidelined since June 13.

• Michael Brenly, son of Cubs television analyst Bob Brenly, hit his third homer and Nelson Perez hit his second in Double-A Tennessee's 13-6 loss to Birmingham on Thursday. Jae-Hoon Ha, who will play in the All-Star Futures Game, had two hits and is batting .253.

Jacob Rogers went 4-for-4 with two home runs in Mesa's 11-2 win over the D-backs in Rookie League action.

• Randy Wells, designated for assignment on Wednesday, has cleared waivers and been outrighted to Triple-A Iowa. Wells will join the Iowa Cubs' rotation. Wells was 1-2 with a 5.34 ERA in 12 games with the Cubs, including four starts. As a starter, he was 0-2 with a 7.04 ERA.
