Later today, 21-year-old right-hander Deivi García will make his playoff debut in Game Two of the ALDS. The Yankees announced as much yesterday, when they made the surprising decision to push Masahiro Tanaka back to Game Three against the Rays. The Yankees have shown confidence in García, but the move likely has more to do with Tanaka that it does the former top prospect.
As Tyler mentioned in his writeup of the news, the main reason for pushing Tanaka back one day likely is to give the veteran a bit of extra rest.
