TORONTO -- The Toronto Blue Jays added left-hander Hyun Jin Ryu to the 10-day injured list Sunday with left forearm inflammation.
The 35-year-old Ryu was pulled after just four innings in Saturday's 7-4 loss to the Oakland Athletics. He lasted less than that in his first start of the season April 10, when he allowed six earned runs over 3 1/3 innings in a 12-6 loss to Texas.
"Of course I'm concerned," Toronto manager Charlie Montoyo said Saturday. "We're going to see how he feels."
Ryu, who won 14 games for the Blue Jays last season, is in the third year of a $80-million, four-year contract with Toronto, and is a major piece to the Blue Jays' postseason hopes.
