Pitcher 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. After not playing in the majors in 2009, he 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.
Bonser was selected by the San Francisco Giants in the first round of the 2000 amateur draft. He was signed by scout Alan Marr and made his pro debut that summer. After the 2003 season, he was traded to the Minnesota Twins along with Joe Nathan and Francisco Liriano for A.J. Pierzynski. Bonser made his big league debut in 2006.
In the minors from 2001 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.
He was born "John Bonser" but legally changed his name to "Boof", a longtime nickname, after the 2001 season.
