Matt Shoemaker injury update: Blue Jays starter leaves game with knee injury


Matt Shoemaker, the Blue Jays' most effective starter this season, left Saturday's game against the Athletics with a left knee injury.

The righty suffered the injury in a rundown in the bottom of the third inning. Afterward, he repeatedly slammed his fist on the ground in pain and frustration as trainers tended to him.

Toronto later announced he had been diagnosed with a left knee sprain. He will undergo an MRI Sunday.

Signed by the Blue Jays to a one-year, $3.5 million contract in the offseason, the 32-year-old Shoemaker is off to a great start. After three scoreless innings Saturday he has a 3-0 mark and a 1.57 ERA in 28 2/3 innings.
