The Toronto Blue Jays acquired righthander Jason Frasor from the Chicago White Sox on Sunday for righthanders Myles Jaye and Daniel Webb.
Frasor, who is a reliever, posted a 3-3 mark with a 3.60 ERA in 64 appearances with the Blue Jays and White Sox last season.
The 34-year-old Frasor has spent his entire career in Toronto prior to being sent to the White Sox last season.
Fraser was sent to the Windy City along with Zach Stewart for Mark Teahen and Edwin Jackson.
Jaye, 20, played in the Appalachian League last season while Webb, 22, has competed for Single-A Lansing.
