Adam Everett followed Kent's hit with an RBI double. When Cubs
left fielder Moises Alou tried to pick up the ball, he knocked it
into the ivy on the outfield wall. As Alou held up his arms to
indicate that the ball was lost in the ivy, Everett circled the
bases on the two-base error and gave the Astros a 4-1 lead.
Astros second baseman Jeff Kent left Tuesday night's game against the Cubs after he strained his right hamstring running out a double in the fourth inning.
