Is Masahiro Tanaka the real deal?

Masahiro Tanaka is a sight for sore eyes. When the Yankees signed him last winter, they clearly weren't expecting what they got. In fact, Tanaka has been so good as of late, that he is an early candidate to start the All Star Game. Tanaka's velocity has been up as of late, and he is showing me that he can pitch in clutch situations. With all the Yankees pitching issues as of late, I wouldn't be surprised if Tanaka becomes the Ace and future Captain.
