TORONTO — The Blue Jays have optioned right-hander Chad Jenkins to Triple-A Buffalo to clear a roster spot for lefty Brad Mills.
The Blue Jays claimed Mills off waivers from Oakland on Thursday, bringing him back to the team that drafted him in 2007.
Mills went 1-1 with a 4.41 ERA in three starts with the Athletics. He has a career record of 4-4 with a 6.98 ERA in 18 games with Toronto, the Los Angeles Angels and Oakland.
Jenkins had no record and a 3.72 ERA in 15 appearances with the Blue Jays this season before he was sent down Friday.
