Mike Rouse was born in San Jose, CA, attended Gunderson High School and Valley Christian High School (where he hit .517 as a senior), and went to college at California State University, Fullerton, the same place where future teammate Mark Kotsay went. He was "All Big West" at Fullerton in 2001, hitting .377 with 12 home runs. He was picked in the fifth round of the 2001 amateur draft by the Toronto Blue Jays. Signed by scout Demerius Pittman, he began to move his way up the ladder, playing mostly shortstop in the minors, with some time at third base and second.
After the 2002 season, Rouse was traded to the Oakland Athletics for Cory Lidle. He spent parts of four seasons playing for the Triple A Sacramento Rivercats from 2003 to 2006. He made his debut in the major leagues with the A's in June 2006, when regular second baseman Mark Ellis was injured. In 8 games, Rouse hit .292 with 3 doubles.
