Technically, no, because gravity exists and the release angle in which the ball is thrown. Even a "rising" fastball sinks. They just sink much less. Aroldis Chapman for example has an 11.2 inch "rise" on his fastball, but it obviously has sink to it because of the release angle and gravity doing it's work. Mike Leake on the other hand is at 5 inches, which is a whole lot less "rise", meaning it is actually "sinking" 6 inches more than the one that Chapman throws. But Leake in 2010 was getting 9 inches more "sink" than what Chapman was last year. Leake has lost nearly 3 full inches of "sink" on his sinker since 2010.
