Smart, low-risk moves: $4 for Tim Wakefield and $3.85 for Sexy Lips.
Wakefield posted a 4.76 ERA (100 ERA+, perfectly league-average) last season. Back and shoulder problems limited him to one start in the post-season. Tavarez's ERA was 5.15 (92 ERA+) in 23 starts and 11 relief appearances.
Boston also acquired outfielder Sean Danielson from the Cardinals (completing the Joel Pineiro trade) and put him on Portland's AA roster.
Catcher Kevin Cash is now a free agent, after turning down an assignment to Pawtucket. Doug Mirabelli filed for free agency on Thursday.
