GLENDALE, Ariz. — Brandon Beachy and Chris Withrow, both of whom had Tommy John procedures on their right elbow last year, aren’t the only pitchers in camp recovering from major surgeries.

Right-hander Ben Rowen, a non-roster invitee, had thoracic outlet surgery on his right shoulder last November. It’s the same surgery that ended Josh Beckett’s 2013 season with the Dodgers.

Beckett had the surgery in July 2013 and was ready to go by the beginning of spring training in 2014. The Dodgers signed Paul Maholm as insurance and he was never needed because of Beckett’s shoulder.

Rowen is a bit behind where Beckett was this time last year. He is planning to throw off a mound for the first time since the procedure on Thursday with an eye on being ready by Opening Day.

“In a normal spring, I’d already have a good amount of bullpens done,” Rowen said, “but I’m feeling good.”

Rowen has an unusual repertoire. His fastball barely touches 80 mph. His sinker is even slower, though it’s got more movement than anyone’s in the game. Rowen also said he has a changeup. We can’t wait to see what the radar gun has to say about that pitch.

The 25-year-old from Rancho Palos Verdes also relies an unusual submarine delivery. He limited right-handers to a .250/.291/.357 slash line at Triple-A last year and lefties weren’t much better, at least when it came to slugging percentage (.282/.360/.359). He made eight major-league appearances with the Texas Rangers, who released him at the end of the season. Actually, they were required to by an obscure rule.

The Dodgers signed Rowen to a minor-league contract with an invitation to spring training in January. He’s a longshot to make the Opening Day roster but should be an interesting pitcher to watch in camp once he gets going.

Coincidentally, Rowen had his procedure performed by the same Dallas-area surgeon, Dr. Greg Pearl, that operated on Beckett.
