"The gentlemanly debate began earlier in the week, with one school of thought in the clubhouse emphasizing the need for power-hitting as a key way to help the team out of another seemingly endless funk, and the other suggesting perhaps too much was being made of the lack of it.

Wednesday night, power-hitting was the way for the Astros to snap their second eight-game losing streak of the season in dramatic fashion.

Carlos Lee hit a walk-off two-run blast — his first homer of the season — in the bottom of the ninth inning, and the team that entered the game tied for fewest dingers in the majors with nine picked up two big ones en route to a 4-2 victory over the Diamondbacks before 21,030 at Minute Maid Park.

Rookie shortstop Tommy Manzella hit his first major league homer, a two-run blast to the Crawford Boxes in the second inning, and the Astros got a quality start from Brett Myers en route to their first home win since April 25 and first multi-homer game since April 10.

"We really needed a win tonight, and it kept us close," Manzella said of the home run he is bound to remember the rest of his life. "And our pitching was outstanding tonight.""
