CHICAGO — Carlos Zambrano's tantrum kept escalating. The emotional ace of the Chicago Cubs went wild, throwing a ball into the outfield, heaving his glove and then whacking a dugout drink dispenser with a bat.

It was an outpouring of anger yesterday that likely will lead to a suspension for the excitable right-hander.

As he argued a close play at the plate, Zambrano appeared to nudge umpire Mark Carlson and was ejected. That set off the 6-foot-5, 255-pound right-hander in the seventh inning of the Cubs' 5-2 win over the Pittsburgh Pirates.

"I overexaggerated after that play to throw the ball and to do the other things, you know," Zambrano said after the game. "Hopefully MLB will review the play and we'll see what happens."

With the Cubs leading 2-1 and Zambrano closing in on his 100th career win, Nyjer Morgan led off the seventh with a single to left and went to third when the ball got by Alfonso Soriano for a two-base error.

When a Zambrano wild pitch bounded a short distance from catcher Geovany Soto, the speedy Morgan broke for the plate. Zambrano went to cover and took the throw. Morgan slid as Zambrano blocked the plate and Carlson called him safe.

Zambrano jumped up, argued the call and appeared to make contact with Carlson, prompting the ejection. He then pointed in Carlson's face and gave him the ejection sign.

Zambrano wasn't finished. He threw a ball into left, slammed his glove against a dugout fence and whacked the drink dispenser on his way to the clubhouse.

"I apologize to him. Like I say, after he kicked me out, I should have gone to the clubhouse and kept watching the game," Zambrano said. "I apologize to throw the ball and do other things.

"I should have control of myself in that situation."

Carlson was not available for comment after the game. It was the Cubs' second run-in with the crew in the series. Lefty Ted Lilly was ejected Monday by Bob Davidson from a game in which he wasn't even pitching after questioning a ball-strike call from the dugout.

"I'm the only calm, cool, collected one around here it seems," said Cubs manager Lou Piniella, who's been known to throw bases and kick dirt during tantrums. "Just kidding."
