1. New York Yankees
The New York Yankees have the deepest rotation entering the 2010 season, having the luxury of making veteran Andy Pettitte their No. 4 starter. Not much needs to be said about Cy Young award winner C.C. Sabathia at the top of the rotation, and it is fair to say that he has lived up to his enormous contract thus far. The addition of Javier Vazquez and the development of Joba Chamberlain are they keys to this year’s success. Last year Chamberlain was held to a pitch count, but look for the Yankees to set him lose in order for him to prove that he belongs as a starter. If Chamberlain can’t get the job done, the Yankees will look to young Phil Hughes to step in as the team’s fifth starter. If Vazquez can duplicate his stellar numbers and Cy Young-worthy performance from last year, it is going to be a long season for all opposing hitters.
2. Boston Red Sox
The Boston Red Sox enter the 2010 season among the teams with the top rotations in the game, but might also have the best front three in the game as well. With the departure of Jason Bay and going on the second year without longtime Red Sox Manny Ramirez, the Sox will rely heavily on Josh Beckett to lead them to the postseason. The Red Sox decided to devote most of their offseason money towards former Angels Ace John Lackey to solidify their rotation. Lackey has a history of missing significant time, but if he can stay healthy he might be the best No. 2 starter in baseball, and will fit nicely in front of young lefty flame-thrower Jon Lester. Dice-K must also have a bounce back year in order to solidify the back end of their rotation with young Clay Buchholz.
3. Arizona Diamondbacks
The Diamondbacks possess arguably the strongest rotation in the National League. Last season Brandon Webb only made one start before having season ending surgery in August to repair his shoulder. All you have to do is look at Webb’s numbers when he is healthy. He is always among the leagues best starters, and uses his heavy sinker to keep the ball down in the strike zone. Webb threw today off flat ground and seems to be right on schedule to open the season. Dan Haren had a tremendous year in Webb’s absence last year, throwing well over 200 innings and pitching to a 3.14 E.RA. The main reason why the D-Backs find themselves in the top 5 is due to the addition of Edwin Jackson from Detroit. The Diamondbacks have question marks at the end of their rotation as most teams do, but, with Jackson solidifying their top three, this team will prove they’re a force to be reckoned with in the NL West.

5. San Fransisco Giants
