Brad Bergesen was drafted by the Baltimore Orioles in the 4th round of the 2004 amateur draft. He was signed by scout Ed Sprague and made his pro debut that summer. In 2006, Bergesen battled mononucleosis, which kept him off the field for a month and sapped his strength for the whole summer.
Bergesen won his major league debut with the Orioles on April 21, 2009, giving up 4 hits and only 1 earned run in 5⅔ innings against the Chicago White Sox. He was the Orioles' Minor League Pitcher of the Year in 2008.
