I was listening to MLB radio and one of the announcers who pitched in the mlb was talking about Sanchez was talking about his sinker and he said when he is throwing it down in the zone with that type of movement and the angle he creates it's almost impossible to hit it in the air. He went through a number of former pitchers who threw with a lot of movement and went through the time that it took for these pitchers to harness, understand and control that movement, but when they did they were devastating pitchers. He said when sanchez gets up in the zone and that movement flattens out he can get rocked, but his upside is tremendous.
I fully understand that Sanchez needs to reduce his walk rate, and improve all three pitches. People are trying to define what Sanchez is and will always be when the kid is 22. He literally is changing every start and what he is today could be very different that what he is mid season. You can't just judge young players solely with statistics. In his first couple starts Sanchez did not look good on the stat sheet, or with the eye test. He didn't have great movement and was leaving the ball up a lot. The last couple starts his pitches have been better quality pitches. He hasn't given up runs which means nothing to the guys who want to proclaim that he's been terrible, but what it has done is given the kid a boost confidence and this matters. This could help place a small building block on the road towards Sanchez improving on the road to which both statistical nerds and qualitative assessments with eventually come together in recognizing he's a pretty good pitcher. How long will it take for him to become a good pitcher...weeks, months, years, never...it's really not that easy to say. Baseball just isn't as easy as some who proclaim themselves to be "real fans" would like to believe.
