Brower was originally drafted by the Pittsburgh Pirates out of Minnetonka High School in the 56th round of the amateur draft, but did not sign, choosing instead to attend the University of Minnesota, where he was named a Big Ten ConferenceAll-Star and Dave Winfield Award recipient in 1994. He was drafted by the Texas Rangers in the 6th round of the 1994 draft, and signed on June 5. He spent nearly four years in the Rangers system before being released early in 1998.

He did not pitch for the Marlins at the Major League level, but appeared in 16 games for their AAA club. Brower signed a minor league contract with the Pittsburgh Pirates prior to the 2007 season, but was given his release to sign a minor league contract by the New York Yankees, and served as the closer for their AAA club, posting a 1.65 earned run average and earning 20 saves. On August 6, 2007, he was promoted by the Yankees, replacing Mike Myers on the 40-man roster. In December, Brower agreed to a minor league contract with the Cincinnati Reds. On May 30, 2008, Brower was traded by the Reds to the Chicago Cubs for cash considerations. Brower was released in July and signed with the Houston Astros.
