The Angels' bullpen has faltered a bit this season, ranking 20th in the majors with a 4.22 ERA (Boston is second at 3.14). Closer Francisco Rodriguez, however, is having another dominant year. He has a 1.93 ERA with a win and two saves vs. Boston. Normally reliable setup man Scot Shields, however, is having an off year, and has a 8.10 ERA vs. the Sox in 2007.
