Red Sox acquired RHP Joel Hanrahan and INF Brock Holt from the Pirates for OF/1B Jerry Sands, RHPs Stolmy Pimentel and Mark Melancon and INF Ivan DeJesus, Jr.
The deal is now official. The Pirates weren't willing to pay Hanrahan another raise in arbitration, especially after re-signing Jason Grilli, but he should be excellent insurance for the oft-injured Andrew Bailey. The 31-year-old right-hander has saved 76 games over the past two seasons. He is currently due to become a free agent next offseason.
