Bronson Arroyo is a great example of recent transactions with the Pirates that have benefited the Red Sox. In February of 2003, the Red Sox plucked Arroyo off waivers and into the mix of pitchers that helped carry the Red Sox to the 2004 World Series Championship.
The Pirates would love to have a guy like him back in their rotation. Maybe the Sox would, too?
Either way, the Sox need to stop losing to the Pirates!
