His sinker was the best pitch parlayed from a starting pitcher in the AL East. That's not rocket science. He threw one pitch 85% of the time and won 38 games in 2 yrs with sub 4ERAs. Thats impressive. His slider and change were league average or worse, but they were improving at the time of his injury. All of that is moot now. Blowing out your shoulder is bad. Guys never come back with the same stuff as before. Its always either recurrent injury from here on out, or less velo, or less control, or less movement. Wang didnt have a large amount of reserve either way. If he's throwing 90-92mph even with his awesome sink, then he's gonna get hit. If he's throwing 95-96 without the great sink, then he'll get pounded. His room for error is nil. He needs to have that biting sink at low to mid 90s velocity or he becomes a pinata.
