Las Vegas Trades for Catcher

Las Vegas trades relief pitcher Miguel Arredondo and OF Drew Fenwick to Boston for C Sammy Yamamoto, infielder Derek Mahan, and a third round draft pick.

Yamamoto, 24, will get a chance to start in Las Vegas. He's a career .185 hitter in 399 at bats. After showing good power in 2011, he only hit one homer last year. Mahan is described as a future gold glove candidate at short, though his bat is questionable.
