The Yankees have the best record in baseball, and lead far and away baseball's best division. But they aren't without their flaws.
Alex Rodriguez, Mark Teixeira, and Derek Jeter, their three best players just a season ago, have struggled on the season. Their rotation, led by Cy Young contender CC Sabathia, has been otherwise quite shaky. And until recently, their bullpen appeared to be in shambles outside of closer Mariano Rivera.
But all that changed around a month ago. The Yankees acquired reliever Kerry Wood from the Indians, and the re-energized bullpen has the best ERA in baseball over the past month. Wood, who has 15 strikeouts and only a single earned run since joining the team, has stepped into the setup role. Former setup-man Joba Chamberlain has also settled down, with a 2.25 ERA on the month, and Rivera has been solid all season long.
Can this continue?
Mariano is Mariano, and Wood has some track record of success from the bullpen, showing off his closing skills with the Cubs in 2008. Joba, despite his early season failures, also has a track record as a premier middle reliever, and his underlying numbers, especially his strikeout rate, have been strong all season. 25-year-old David Robertson is also one of baseball's most dominating young middle relievers, and despite shaky control, his incredible stuff makes him a solid option for any bullpen.
The Yankees have the best lineup in baseball, but a rotation that is, for now, quite shaky. With this kind of offense and bullpen backing them up however, Sabathia, Burnett, Pettitte, and Co. will have a much easier time winning games come October, and should be able to return the Yankees to the World Series.
