The San Diego Padres traded minor league pitcher Matt Bush to the Toronto Blue Jays on Tuesday for a player to be named or cash. Bush, the No. 1 pick in the 2004 amateur draft, was designated for assignment Thursday, ostensibly to make room on the 40-man roster for slugger Cliff Floyd. However, hours after Floyd's signing was announced, the Padres acknowledged they were looking into another off-field incident involving Bush. Police in suburban El Cajon later confirmed that the 23-year-old Bush was being investigated for allegedly assaulting members of a high school lacrosse team. Originally drafted as a shortstop and given a $3.15 million signing bonus by his hometown team, Bush flopped as a position player with San Diego and was converted to pitcher.

He led the South Atlantic League in batting average and on-base percentage (.407) and ranked third in slugging percentage (.506). Fryer was originally selected by the Brewers in the 10th round of the 2007 First-Year Player Draft out of Ohio State University. He will be assigned to Single-A Tampa.
