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.

He hung around parts of 3 seasons in Baltimore and pitched in 2012 with the Arizona Diamondbacks. After spending 2013 with the Chunichi Dragons of NPB, he spent parts of a handful of seasons in the Atlantic League before walking away.
