"We're going to cut down on his swings," Guillen said. "He ain't swinging no more. ... He's done with that. Now he's just going to bunt, bunt and bunt. No more home run derby for him."
Over the last 10 seasons, Zambrano has hit 24 home runs, including one this year on June 3 against the Phillies. He leads all active pitchers in home runs. But after Zambrano experienced lower back stiffness during his last outing and left after 2 1/3 innings, Guillen wants to cut back on Zambrano swinging for the fences as a precaution.
Guillen doesn't believe Zambrano's swings were the reason for the injury -- which isn't expected to delay Zambrano's next start -- but the Marlins skipper wants to minimize the pitcher's home run cuts as a cautionary and preventative measure.
"You see Carlos, Carlos puts on a show when he hits. He does," Guillen said. "That's why we have to control that and make sure. I'm not going to say he's not going to hit, but I don't want him to. You don't win games in batting practice. I don't want him to start swinging the bat like that."
Fortunately for Guillen, Zambrano's next start is Friday at Tropicana Field -- an American League ballpark that will require the Marlins to use a designated hitter.
"Good," Guillen said. "He doesn't have to hit."
