Martinez is not in Saturday's lineup as he is dealing with soreness after colliding with an outfield wall Friday night, Jason Mastrodonato of the Boston Herald reports.
Martinez made a running catch into the wall during the third inning Friday, although he was not forced to exit the game. The 30-year-old is apparently experiencing general body soreness after the collision but will not undergo additional testing, so it seems to be a minor issue. Martinez should be considered day-to-day for the time being.
