Here is the complete list of pitchers on the Yankees' current 40-man roster that pitched more than 5 innings of relief in the majors last year:
DRob 66.1 IP / 2.04 ERA / 2.4 WAR
Warren 77.0 / 3.39 / 1.2
Nuno 20.0 / 2.25 / 0.7
Thornton 43.1 / 3.74 / 0.5
Claiborne 50.1 / 4.11 / 0.3
Kelley 53.1 / 4.39 / 0.0
Phelps 86.2 / 4.98 / -0.1
Phelps's numbers are total including starting appearances.
As it stands this is one incredibly thin-looking pen.
I know they have a bunch of young guys who'll be auditioning.
It's very surprising, though, that they didn't pick up a guy like Balfour, who seemed like a great fit at a reasonable cost.
Have to think there are more moves coming...but it's still a little puzzling.
