The Red Sox will only pay Atchison $40K more than the MLB minimum in 2011. That's a bargain considering the 34-year-old threw 60 innings of 4.50 ERA ball with 6.2 K/9 and 2.9 BB/9 last year.
Boston chose to pay Hall a $500K buyout instead of guaranteeing him $9.25MM in 2011. The 30-year-old utility man batted .247/.316/.456 with 18 homers in 2010 and he played every position but first base and catcher (he even pitched). Hall is an unranked free agent, so the Red Sox won't obtain draft pick compensation if he signs elsewhere.
They could obtain a compensation pick if Lopez, a Type B free agent, turns down arbitration to sign elsewhere. That possibility appeared to contribute to the team's interest in the infielder when they signed him in September. Lopez batted .233/.311/.345 in 441 plate appearances for the Cardinals and Red Sox.
