The Red Sox did not tender contracts to righthander Scott Atchison, lefthander Rich Hill, and outfielder Ryan Sweeney. They are now free agents.
Atchison, 36, appeared in 42 games last season, posting a 1.58 ERA. He struck out 36 and had only six non-intentional walks in 51.1 innings. But Atchison also tore a ligament in his elbow in July and elected not to have surgery. He returned in September and pitched well in five games.
