Bush, now 24, was the first overall pick by the Padres in the 2004 draft. A shortstop at the time, Bush's signability pushed him past Stephen Drew, Jered Weaver, and Jeff Niemann on Kevin Towers' list. He was arrested on felony assault charges weeks after the draft, resulting in a suspension. Injuries hampered his progress, and the Padres converted him to pitching in May of '07. He had Tommy John surgery later that year.
Bush was charged with assault again in February of '09, and the Padres designated Bush for assignment and traded him to the Blue Jays. The Jays released him in April, and more incidents surfaced in June.
