The Red Sox have more pitching than any team in baseball at the moment, but they still have some concerns. Tim Wakefield will be 43 next month and has had some physical problems late in the last two seasons. John Smoltz is 42 and, in effect, still rehabilitating. Daisuke Matsuzaka (pictured) is on the disabled list and Brad Penny can put strain on the bullpen. Obviously, the presence of a healthy Jon Lester and Josh Beckett is an enormous blessing and should keep the Red Sox out of long losing streaks. Assuming he is not traded, Clay Buchholz offers an additional option. But there is some potential for some instability here beyond the top two starters, a problem that most every team in baseball deals with. This year, the Red Sox really haven't.
