The Red Sox pitching staff is going to be shuffled up a little bit.
The move is expected to happen Monday because, I presume, Bonser last piched on Tuesday, so he'll have enough rest to contribute right out of the bullpen. Meanwhile, Atchison can work over the weekend if the Sox need him to.
Bonser will most likely be in a long relief type role. With Tim Wakefield in the rotation and Josh Beckett on the disabled list, the Red Sox really haven't had a long relief specialist. Bonser should fill in nicely.
