Zimmerman, who is looking to make his second All-Star appearance, is hitting .306 with 11 home runs and 32 RBIs entering Tuesday's action.
"Zim is just an all-around All-Star, regardless if he makes the All-Star team or not," teammate Willie Harris said. "He is an All-Star in our locker room -- he is a leader, and he's our guy. That's all to it. He's a star, even when he's not playing baseball. He's an All-Star guy."
Zimmerman isn't the only one who has a chance to make the All-Star team. Catcher Ivan Rodriguez continues to get votes, and he ranks fourth, with 577,022 votes, ahead of the Dodgers' Russell Martin. Cardinals receiver Yadier Molina continues to lead NL catchers, with 762,875 votes, ahead of Atlanta's Brian McCann and Philadelphia's Carlos Ruiz.
