The Red Sox claimed Matt Fox off of waivers from the Twins, according to Joe Christensen of the Minneapolis Star-Tribune (via Twitter). The Twins designated the right-hander for assignment Sunday to create roster space for Ben Revere.
Fox, who turns 28 this December, pitched well in his MLB debut Friday, limiting the Rangers to four hits and a walk in 5.2 innings of work. He pitched 123 innings as a swingman in Triple A with a 3.95 ERA, 7.6 K/9 and 3.7 BB/9. Fox has a 3.71 ERA in his six-year minor league career with 7.8 K/9, so he's a nice depth addition for Boston.
