The Cubs' left-handed-hitting third baseman was 2-for-2 against lefties entering Tuesday's game against Milwaukee southpaw Chris Narveson. He had a .229 career average against left-handers before going 0-for-3 against Narveson in the Cubs' 7-4 loss.
"I don't ever want to think of myself as a platoon type of player where I need to sit against lefties," Stewart said. "I take pride in hitting against them -- I've done that my whole career. There wasn't any part of me thinking, 'I'm not playing today.' I was glad to see my name in the lineup, and this gives me a chance to continue to face them and see what I can do against them and be an everyday player."
Stewart hit safely in each of his starts before Tuesday's game. On Sunday, he singled off Nationals lefty Sean Burnett in the eighth, and on Monday night, the Brewers called on Manny Parra to face him in the ninth, and he doubled. Stewart said he tries to prepare for everybody.
"It's not so much that it's a lefty coming in, I just like to know what a guy throws and maybe what his out pitch is and not so much what his hand is," he said. "My dad threw to me when I was growing up and he was left-handed, and I like to think that helped a little bit."
Before a series, Stewart will make sure he looks at video of an opposing team's left-handed relievers.
"He's swung the bat as good as anybody," Cubs manager Dale Sveum said.
