We currently have a group equal to the populus of an island nation ready to compete for spots in the bullpen this spring. When all is said and done, I believe Edwar Ramirez will emerge as the stud 8th inning guy the Yanks have been lacking (sans Joba The Beast). Having a go-to, dominant, strikeout pitch is the main ingredient to being a dominant big league reliever, and Edwar certainly has one in his change.
First, PECOTA loves him. 76 ks in 60 ip and a 3.61 era are projections every Yankees fan would happily sign for. Scouts all agree that Edwar's changeup is a 'plus, plus' pitch scoring an 80 on the 20-80 scale. The quality of this pitch can be seen in the 31 ks in 21 major league ip in 2007.
Second, Edwar will be 27 in spring training this year. The 31 ip Edwar threw last year were his first in the bigs; he is the perfect age for a break out.
The best comp for Edwar is probably Keith Foulke. Foulke had (has?) the same kind of changeup as Edwar. Foulke likewise struggled a little bit early in his career as he searched for the proper complimentary pitch to go with his great change. Once Foulke was able to spot his 85-88 mph fastball effectively he became a dominant reliever. I believe Edwar will do the same. When you have the dominant pitch, your other pitches need only be average to keep hitters honest. A little Mo 'cut', a little Wang sink, or simply being able to spot his fastball better will give Edwar the secondary pitch he needs to be a top reliever.
Now that Gator has been replaced by someone who can actually make additive changes to a pitcher, and with the first year under his belt, I believe Edwar will become a dominant force in the Yankee pen for a long time to come.
