News: Martinez has signed a minor league contract with Boston, Sox Prospects reports.
Impact: The 29-year-old Martinez split time last season between the Angels and Athletics organizations, playing for both teams' Triple-A affiliates. He has 32 games of major league experience and could serve as the insurance callup at catcher should Christian Vazquez or Ryan Hanigan suffer injury in Boston. The Red Sox inked two veteran backstops -- Humberto Quintero being the other -- and either Martinez or Quintero can replicate the role of Dan Butler last season. Butler, who spent some time at Boston last season, was designated for assignment in the offseason and traded to Washington in January 2015.
