Iggy,
The video I posted encapsulates why the Yankees have the best record in baseball since August 2. August 2 is when Gary Sanchez was called up to the Yankees. He has been a highly touted player for some time and he has been in the Yankees system since he signed at age 16. He is obviously extremely talented but he is also a winning baseball player. The Rays tried to intentionally walk Sanchez. 90% of major league players getting an intentional walk throw it into relax mode and are not ready if the other team fails to execute. The Rays had a sloppy, lazy execution and left the pitch which was supposed to be an intentional ball up and way too close to the plate. Sanchez was ready for a sloppy pitch, jumped out and attacked the 52 mph lazy floater and almost parked it into the bullpen supplying his own power. He refused to accept the walk and aggressively attacked. His teammates see a play like that and they are infused with confidence the same way Derek Jeter used to make winning plays which inspired his teammates, diving into the stands and making flip throws to the plate from positions no players ever think to put themselves in. And as you mentioned Sanchez is doing it on defense as well, with snap throws from the knees to pick off baserunners who take big leads and get lazy with their attention spans.
The Rays manager later admitted he was "embarrassed" by the Sanchez RBI sac fly and didn't want to discuss. The pitcher was quoted saying the pitch "slipped" because his hands were "sweaty." It was just bad execution by the Rays and aggressive, heads up, winning baseball by Sanchez and it shows, in one play, why both teams are where they are in the standings. See this:

Gary Sanchez is the best catcher in the major leagues right now bar none.
