Each member of the rotation has shown exactly what they can do when they are making their pitches. #1-4 could easily shutdown a line-up on a given night. #5 Wakefield, can keep the Sox in most games and can throw about 500 innings a year. At this point, it seems Epstein made the right call in keeping Lester instead of pulling the tigger on the Santana deal.
Now, I can't think of many teams who are that strong #1-4, have a solid closer and a catcher to keep everything together. Can you? The bats will come around. No one can score 7-10 runs every game, but with good starting pitching the Red Sox may not have to.
