Who could have known what Cashman had assembled?
Colon and Garcia have been outstanding, combining for 288 innings of 3.63 ERA ball. Colon has given the Yankees a 3.71 FIP, Garcia a 4.02.
In the bullpen, Cory Wade and Luis Ayala have performed admirably. Wade's pitching triple slash (ERA/FIP/xFIP) is a very respectable 2.16/3.71/3.68, while Ayala's is 1.80/4.02/4.07. Despite that their ERA's do not match up well with their FIP's, each has been much better than anyone could have expected from a minor leage free agent.
Between these four minor league free agents, who have given the Yankees a combined 376 1/3 innings, they have accumulated 5.3 fWAR. Now, combine that with the signing of Andruw Jones and another minor leage free agent signing in Eric Chavez, and the Yankees receive another 1.7 fWAR.
If you're keeping track at home, that's 7 fWAR from under-the-radar signings, players who, in a perfect world, would just be depth.
These types of minor league signings are the ones that we generally assume are replacement level players, but in their own ways, they have provided much more than that. With just minor league free agent deals, Brian Cashman has helped piece together a roster that seemed incomplete.
While Cashman is under constant scrutiny for not making the big splashes, he has made smaller moves to complete a Yankees team that is just a few games away from clinching a postseason birth.
