Rizzo is batting .392 since April 26 with nine doubles, three homers and 16 RBIs, and has struck out eight times in that stretch. Before those 18 games, he was batting .173 with 26 K's.
"I just say keep it as simple as possible," Rizzo said. "In Miami, the first game there [April 25], I was trying to do way too much. We took it back a couple notches, a couple steps, and it's been paying off. I'm just keeping it real simple and not trying to do too much and that's what I always say and live by."
• Luis Valbuena returned to the Cubs lineup Wednesday for the first time since he sprained the little finger on his right hand sliding into third base on Saturday. The third baseman may have some tenderness on his hand, but should be fine, Sveum said.
"When we got him on waivers last year before Opening Day, he had all the intangibles of a guy who gives you good at-bats, a left-handed hitter, always reliable defensively no matter where you put him, and has the ability to hit home runs," Sveum said. "He's getting the opportunity, and basically every at-bat he has is a quality at-bat."
The Cubs claimed Valbuena off waivers before the start of the 2012 season.
