"Reliever Trystan Magnuson bas bounced back like a bad cheque.

The Blue Jays re-acquired the Vancouver-born Magnuson from the Oakland A's for cash on Friday. He'll re-enter the mix for employment in the 2012 bullpen.

A year ago this month the Jays dealt relievers Danny Farquhar and Magnuson to Oakland for outfielder Rajai Davis.

Magnuson, 26, a first-round pick of the Jays in 2007 from University of Louisville was given a $462,500 signing bonus, pitched 142/3 innings for Oakland last season, or roughly what Joel Carreno pitched for Toronto.

Magnuson had a 6.14 ERA with five walks and 11 strikeouts. At triple-A Sacramento Magnuson, the nephew of the late Keith Magnuson, NHL hall of famer, was 4-2 with a 2.98 ERA and five saves in 30 games. He walked 19, fanning 46 in 45 1/3 innings.

The 6-foot-7 Magnuson was 8-10 with a 3.53 ERA in 113 games (24 starts) in three seasons in the Jays system, striking out 280 in 226 2/3 innings."
