KANSAS CITY, Mo. — Left-handed relievers Tim Collins and Francisley Bueno have been put on the 15-day disabled list by the Kansas City Royals.

The Royals recalled right-hander Michael Mariot and left-hander Donnie Joseph from Triple-A Omaha on Monday.

Collins, who walked two and gave up a hit while retiring only one batter against the Chicago White Sox on Sunday, is out with a flexor strain in his left elbow.

Bueno, who allowed a double and a single while getting two outs Sunday, has a sprained little finger on his left hand.
