Romp in the Park Grand for Womack

When Tony Womack saw his line drive get past Lance Berkman, he just kept running.

Womack hit an inside-the-park grand slam against Billy Wagner in the eighth inning Wednesday night to lift the Arizona Diamondbacks to a 7-4 victory over the Houston Astros.

The Diamondbacks loaded the bases in the eighth against Jay Powell (4-2) with two walks and a hit batsman. Wagner came in and got in front of Womack, 0-and-2.

Womack then lined a pitch to left field that got past a diving Berkman and rolled to the wall. Womack sprinted around the bases and narrowly beat Carlos Hernandez’s relay.

“I’m running and I knew when the ball got past him I had third,” Womack said. “But I didn’t know who got the ball after he missed it. I just had to trust my third base coach [Brian Butterfield]. By the time I was sliding home, all the energy had just sucked out of me.”

Berkman, who has been in the major leagues only six games,, has played in the outfield only two years. He was an All-American first baseman at Rice when he was taken by the Astros in the first round of the 1997 draft.

“When it came off the bat, I thought I had a good jump on it,” he said. “But the closer I got, the more it started to dive down. [Lunging for it] turned out to not be the right thing.”
