Pitcher Sean Burnett attended Wellington High School and went 10-1 with a 1.04 ERA as a senior and was named the AAU Player of the Year. He had been the worst hurler on the US team that won Gold at the 1998 World Youth Championship (1-0, 7.71). Following graduation, he was selected by the Pittsburgh Pirates in the first round of the 2000 amateur draft. He advanced through their organization and reached the majors in 2004. However, he then had Tommy John surgery on September 22, 2004 and missed the entire 2005 campaign. He spent the entire 2006 and 2007 seasons with the AAA Indianapolis Indians.
Burnett was taken off Pittsburgh's 40-man roster on February 1, 2008, to make room for Ray Olmedo, who would be waived shortly thereafter. Burnett was designated for assignment but no team claimed him and he cleared waivers. Pittsburgh invited him to spring training as a non-roster invitee. Burnett said "I was upset and really embarrassed at myself. I'm a former first-rounder. I don't think I've lived up to any expectations I had for myself."
