Left-hander Danny Duffy is headed to the 10-day disabled list with left elbow impingement and valgus extension overload, the Royals announced Saturday. Duffy will be eligible to return on September 5 barring any further complications. In a corresponding move, the Royals selected the contract of left-handed reliever Onelki Garcia from Triple-A Omaha and shifted center fielder Bubba Starling to the 60-day disabled list.

It’s a harsh blow to the Royals’ playoff chances, as the team entered Saturday’s competition just 1.5 games back of a wild card spot. Unless Duffy makes a quick recovery (never a guarantee with elbow issues), making a run at the postseason without their ace starter might prove an insurmountable hurdle.
