The Toronto Blue Jays placed left-hander Tim Mayza on the 10-day injured list on Saturday with elbow inflammation.
It was one of several player moves made by Toronto entering Saturday’s doubleheader against the visiting Boston Red Sox. The Blue Jays optioned left-hander Ryan Borucki to Triple-A Buffalo and recalled right-hander Patrick Murphy and left-hander Kirby Snead from Buffalo.
Toronto also recalled right-hander Trent Thornton from Buffalo to be its 27th man for the twin bill.
Mayza, 29, is 2-1 with a 3.75 ERA in 44 appearances this season.
Borucki, 27, is 3-1 with 5.12 ERA in 20 games this year.
In seven games with Toronto this season, Murphy, 26, is 0-1 with a 5.63 ERA. Snead, 26, has a 0.00 ERA in two appearances with the Blue Jays this year.
Thornton, 27, is 1-3 with a 4.58 ERA in 28 games — three starts — with Toronto this season.
