Boof Bonser pitched three years for the Minnesota Twins. After being mostly a starter in the minors and in 2006 and 2007 in the majors, during 2008 he was primarily in the bullpen. He missed all of 2009 due to a labrum tear, then pitched briefly for both the Boston Red Sox and Oakland Athletics in 2010 in what were the final appearances of his big league career.
Born John Paul Bonser, Boof legally became Boof, his longtime nickname, after the 2001 season. A year prior, he was selected by the San Francisco Giants in the first round of the amateur draft, signed by scout Alan Marr and made his pro debut that summer. In the minors, from 2001 until his MLB debut in 2006, he was usually over .500: 16-4 in 2001, 9-8 in 2002, 8-12 in 2003, 13-9 in 2004 and 11-9 in 2005. After the 2003 season, he was traded to the Twins, along with Joe Nathan and Francisco Liriano, for A.J. Pierzynski.
