HOUSTON (WSAU-TSN) The Brewers bats remained cold on a warm, comfortable afternoon in Hosuton. And by the end of the day, Milwaukee had fallen a game below .500.

Carlos Lee belted a three-run homer in support of Houston starting pitcher Bud Norris, but wound up leaving Sunday's 5-0 win over the Milwaukee Brewers following a violent collision with teammate Angel Sanchez in the seventh inning.

Lee collided with Sanchez in shallow left field while pursuing a ball hit by Milwaukee's Mark Kotsay. It appeared the Astros shortstop kneed Lee in the ribs. Lee remained down for several minutes before being removed from the field on a cart. He was then taken to a local hospital to have tests performed on his left ribcage.

Norris (2-1) limited the Brewers to three hits and three walks in 7 2/3 innings. The right-hander also recorded 11 strikeouts, three shy of his career high.

Jason Bourgeois collected two hits and scored a run for Houston, which took two straight after dropping Friday's series opener.

Chris Narveson (1-2) gave up four runs on seven hits and fanned seven over six full frames for the Brewers.

The Astros produced a run with three consecutive singles by Lee, Brett Wallace and Bill Hall to leadoff the second.

Lee put Houston up 4-0 in the sixth with a blast to the left field seats, scoring Bourgeois and Hunter Pence after they both singled.

Facing Norris with two outs and a runner on first in the seventh, Kotsay hit a fly ball that fell in for a double and left Lee in pain. Yuniesky Betancourt flied out to right field to end the threat when play resumed.

The Brewers open a 4-game series against the Atlanta Braves on Monday. Broadcast time is 5:30pm on AM-550 FM-99.9 WSAU.
