Adam Troy Dunn (born November 9, 1979, in Houston, Texas), nicknamed "Big Donkey", is an American Major League Baseball first baseman, outfielder, and designated hitter for the Chicago White Sox. He bats left-handed and throws right-handed.
He is six feet, six inches (198 cm) in height and weighing 287 pounds. On July 4, 2009, he became the 123rd player to hit 300 career home runs.
Dunn was a standout quarterback at New Caney High School in Texas. After graduating from high school, the Cincinnati Reds drafted Dunn in the second round (50th overall) of the 1998 Major League Baseball Draft. Dunn had previously committed to play football for the University of Texas. The Reds and Dunn agreed to a deal which allowed him to play minor league baseball during the summer, and return to Austin in August to prepare for football. Dunn redshirted his freshman season and served as a backup to Major Applewhite. When star recruit Chris Simms committed to Texas, Dunn was asked to move to the tight end position. As a result, he left the Longhorns to concentrate on baseball in 1999.
