just need a good cutter like mariano rivera, why is that so rare? fastball has to have some fukking movement. none of these guys throw strikes until they have to, it's so predictable, they are so arrogant hoping the hitter will swing at their crappy sinker, and they fool nobody and get themselves in a 3-1 count in no time.
just get guys who can master the CUTTER
the hitter knows it's coming, swings away, and can't hit it, the hitter is on the defense, scared.
