Estrada has completely changed the way he attacks hitters. Whereas before he was following the standard philosophy of attempting to work down, Estrada is now pitching more towards the top of the zone.

But not just anybody can pitch up in the zone and get away with it. There?s a very real reason that Marco Estrada and Chris Young can throw the ball up there and survive. Both of those pitchers get abnormally high amounts of spin on the baseball. In fact, Marco Estrada is one of the leaders in baseball in average spin rate on his fastball and second, to Young, in ?rise.?
Now, obviously a human can?t make a fastball actually rise, but Estrada?s falls at a rate much slower than everybody else?s, to the point that his fastball drops 12.3 inches less than would be expected by gravity. This leads to a lot of batters getting under the ball and hitting those weak flyballs we?ve seen from Estrada all season.
