Veteran left-hander Randy Wolf will undergo Tommy John surgery next week that will cause him to miss all of the 2013 season, writes Dan Connolly of The Baltimore Sun. However, the 36-year-old told Connolly that he plans to return in 2014.
Wolf also underwent Tommy John surgery in July of 2005 as a member of the Phillies, sidelining him for the remainder of the season and the first half of the 2006 season. The lefty was picked up by the Orioles after he was released in the final season of his three-year deal with the Brewers. Wolf posted a 5.65 ERA with 5.9 K/9 and 3.0 BB/9 in 157.2 innings of work for the two clubs.
