The Indians have designated lefty Colt Hynes and righty Frank Herrmann for assignment, the club announced via press release. These moves, along with the DFA of Preston Guilmet, clear roster space for the club's 40-man additions: Scott Atchison, Jason Giambi, and Nyjer Morgan.
Herrmann, 29, is making his way back from Tommy John surgery after missing all of 2013. He threw 120 1/3 innings between 2010-12 with the Indians, putting up a cumulative 4.26 ERA with 5.4 K/9 against 2.2 BB/9.
Hynes, meanwhile, was added in exchange for cash from the Padres back in October. He was knocked around in his first 17 MLB frames last year with San Diego (and in his 5 2/3 spring innings). But Hynes posted a sterling 1.52 ERA in 47 1/3 minor league innings last year, with an even more impressive 11.0 K/9 against just 0.4 BB/9.
