MILWAUKEE -- Matt Carpenter hit a two-run homer and Luke Voit drove in four runs, backing Luke Weaver's 10-strikeout night in a 10-2 win Tuesday over the Milwaukee Brewers.
Carpenter's shot to right in the fifth had added importance for the third baseman after he had pledged $10,000 for every home run that he hit the rest of the season to Hurricane Harvey relief efforts. The Galveston, Texas native looked up and pointed two fingers toward the night sky as he touched the plate to extend the Cardinals' lead to 9-1.

The Cardinals remained in third, five games back of Chicago.
Weaver (3-1) gave up a solo homer to Eric Thames in the bottom of the third. The 24 year-old right-hander otherwise had another solid outing against the Brewers, allowing eight hits and two runs over 5 2/3 innings.
Weaver has a 3.00 ERA in four career starts versus Milwaukee, with 36 strikeouts in 24 innings.
The Cardinals were cruising with a six-run lead when Carpenter went deep against Carlos Torres with one out in the fifth. Teammate Adam Wainwright and the Cardinals organization also have pledged to match Carpenter's long-ball donations for hurricane relief efforts.
