Red Sox signed RHP Caleb Simpson to a minor league contract and added him to the 60-man player pool.
Simpson was supposed to pitch in the Cubs system this year, but the team opted to release him rather than keep paying him $400 per week. The 28-year-old had a 3.00 ERA and a 56/30 K/BB ratio in 42 innings in the Giants system last season. He throws really hard, but walks have been a constant problem for him.
