The Braves have announced that they’ve released starting pitcher Williams Perez. The move clears a spot on their 40-man roster for the Rule 5 Draft, which is about to start.

The 25-year-old Perez has made 31 starts for the Braves over the past two seasons but has mostly struggled, with a 5.18 ERA, 5.3 K/9 and 3.5 BB/9 over 170 1/3 innings. Last season, he pitched 53 2/3 innings in the big leagues and posted a 6.04 ERA, also fighting through shoulder and elbow troubles. The Braves now have ample starting pitching depth of the type Perez provides and therefore could afford to lose him.
