 Fastball outside gets the swing, so they try to go inside here. He misses his spot, goes back outside. They say, you know what? Let's just stay out there. I think that's a missed spot again, but they get the swing and miss. He's been riding that outside line. That's a perfect fastball. And then he goes slider on the outside and the batter is fooled. And he's like, this is hard, man. This whole thing's hard. Look at these two pitches. They start in the same spot. They end in the same exact spot, but one's 10 miles per hour slower. Poof.
