Peter Gammons just said on Baseball Tonight that the Red Sox didn't want Lowe to throw more than 50 pitches. That being the case, it is understandable that Francona took him out after six innings since Lowe had exceeded 50 pitches by quite a bit. Still, he shouldn't have turned to Pedro. If Francona was worried about overusing his bullpen, he should have turned to Wakefield or Arroyo. Both of those guys were excellent in relief in Boston. Wakefield pitched several innings in game five while Arroyo pitched one (Arroyo also pitched for one inning in game six). But you gotta figure that Arroyo (and Wakefield) was okay to go in game seven.
