I am going to give tonight's game a try to see how Tong looks. I am not convinced he is the real deal (at least at present). First he needs better command so he isn't walking so many batters and pitching behind in the count. I am concerned that he basically a 2 pitch pitcher in that 86% of his pitchers are either 4-seam fastball (62%) or change (25%). He has a that he throws almost exclusively to right handed batters. He has a cutter for a 4th option but it accounts for only 3-4% of his pitches. So for left handed hitters, he is basically 4-seamer up or change up down.
It will be interesting to see how he fairs. The Mets really need him to be good (very good).
