According to Hal McCoy in the DDN:
Q: Shouldn’t the Reds be trying to sign Bronson Arroyo to a long-term deal right now? Of course, that’s assuming he wants to come back. Ã¢â‚¬â€ Michael, Wilmington, N.C.
A: And that’s the big assumption one shouldn’t make. Arroyo left Boston kicking and screaming. Because he was traded in the midst of a long-term contract, he has the option of becoming a free agent after the season. If he continues to have a monster year the Red Sox might offer him millions and the deed to The Old Church and Kenmore Square. He hasn’t sold his new house in Boston, either.
I thought it had been determined that Arroyo didn’t have enough major league time to void his deal? If this is true, no matter how good he is this year, one year of Arroyo isn’t worth giving up Pena.
