The Boston Red Sox have placed left-hander Henry Owens on outright waivers, according to media reports on Wednesday, clearing a spot on the team’s 40-man roster.

The 36th overall pick in the 2011 draft, Owens was once considered a top prospect but has struggled with control. He had 121 strikeouts and 115 walks in 126 innings between Triple-A Pawtucket and Double-A Portland last season. He is 4-6 with a 5.19 ERA in 16 career major league appearances.
