WASHINGTON (AP) – St. Louis Cardinals right-hander Joe Kelly has been put on the 15-day disabled list with a strained left hamstring.  The Cardinals also optioned righty reliever Keith Butler to Triple-A Memphis and recalled rookie right-handers Eric Fornataro and Jorge Rondon from Memphis before Thursday’s game at the Washington Nationals. Neither Fornataro nor Rondon has ever appeared in a major league game.

Kelly got hurt while trying to beat out a bunt attempt in the fourth inning of the Cardinals’ 5-1 loss to the Milwaukee Brewers on Wednesday. He is 1-1 with a 0.59 ERA in three starts this season.
