Ryu, 34, was a finalist for the AL Cy Young award last season, going 5-2 with a 2.69 ERA and 1.149 WHIP. So far this spring, Ryu has a 1-0 record with a 1.50 ERA and 0.667 WHIP. This will be his second consecutive Opening Day start with the Blue Jays.
Montoyo said the team is not yet ready to make any further pitching decisions and said he hasn't ruled out Robbie Ray for opening weekend. The lefty, who currently has a bruised elbow, did plyometric work Friday and may soon begin a throwing progression depending on how he's feeling.
Nate Pearson has been doing long toss as of late, and may throw a bullpen in the future -- although no date has been set for that, per Montoyo.
