The Toronto Blue Jays placed rookie pitcher Drew Hutchison on the 15-day disabled list Saturday with an ulnar collateral ligament sprain in his right elbow.

Hutchison was removed from Friday's outing against Philadelphia after just nine pitches with elbow soreness.

The 21-year-old right-hander became the third Toronto starter in four games to make an early exit because of injury and make a trip to the DL.

Brandon Morrow departed in the first inning of Monday's loss to the Washington Nationals with a strained left oblique and Kyle Drabek left Wednesday's setback to the Nationals with ligament damage to his right elbow. Drabek may have to undergo Tommy John surgery for a second time.

Hutchison made his major league debut earlier this season and has compiled a 5-3 record with a 4.60 earned run average in 11 starts.

The latest replacement to be summoned from Triple-A Las Vegas is right-hander Robert Coello, who appeared in one game for Toronto this year, tossing two scoreless innings against Boston on June 1.

Coello posted a 4-1 record with a 3.00 ERA in 19 games (three starts) for Las Vegas.
