Matt Garza did nothing to help his trade value in Saturday's 3-2 victory over the Astros, but he didn't hurt it either with his fourth victory of the year, this one courtesy of Anthony Rizzo.

With a month to go before the trade deadline, Garza (4-6) lasted only 51/3 innings while giving up two runs on nine hits and three walks. He and fellow starter Ryan Dempster, currently on the disabled list, are the two names most frequently mentioned as trade targets.

"Obviously a lot of teams check in with us," Cubs general manager Jed Hoyer said. "Nothing has changed that way and I think it will sort of maintain this (way) until we get a week out and then it heats up as we get to the deadline."

Garza and the Cubs enjoyed seeing Rizzo sock his first homer as a Cub — in the fifth inning with Starlin Castro on base.

"Four games so far, he's got two game-winning hits," manager Dale Sveum said.
