The Toronto Blue Jays have reacquired reliever Jason Frasor from the Chicago White Sox for minor league pitchers Myles Jaye and Daniel Webb. Frasor returns to the Jays after being traded to the White Sox last July as part of the Colby Rasmus acquisition and is under contract for 2012 at $3.75-million after Chicago picked up his option in October.  He was originally acquired from the Dodgers back in March of 2004 for Jayson Werth and has since become the Blue Jays all-time leader in games pitched, surpassing Duane Ward just days before he was dealt.

Frasor is the second bullpen arm gleamed from the White Sox in the last month joining Sergio Santos who was acquired for prospect pitcher Nestor Molina.  He finished last season with a 8.55/3.90/1.05 pitcher slash line,* a 3.60 ERA and 4.04 xFIP in 60 innings and has a career 3.99 xFIP over 478 career innings.

The White Sox, meanwhile, continue their kind of, sort of rebuild by acquiring two more prospect arms from Toronto, although neither are very highly touted. Jaye was drafted by Toronto in the 17th round in 2010 and posted a 3.00 ERA and 4.07 FIP in 54 bullpen innings with the rookie-league Bluefield Blue Jays in 2011 while Webb was an 18th round pick by Toronto in 2009.  Webb pitched most of his 2011 season in Low-A Lansing of the Mid-West League posting a 5.59 ERA and 4.40 FIP in 18 games, 12 of them starts, while battling injuries.

The Blue Jays may have lost out on the Yu Darvish sweepstakes and seem unlikely to make any huge free agent splash this offseason, but the fortification of their bullpen over the last month has been impressive.  Santos, Frasor, and recent free agent acquisition Darren Oliver join incumbents Casey Janssen, Carlos Villanueva, and Jesse Litsch in Toronto’s bullpen; a unit that looks much better now than it did a month ago.
