Torero right-hander David Dunn, a senior who has an arsenal of five pitches, demonstrates the grips he uses to mow down opposing batters.

Fastball
Dunn throws a four-seam cut fastball, which moves in on left-handed batters. "If you can get outs just using your fastball, more power to you," he says. "That leaves the rest of your pitches for the batter to worry about next time."

Curveball
His best pitch, Dunn's curveball is a "12-to-6" curve, which means it rotates from the 12 o'clock position to the 6 o'clock position as it approaches the batter. "The grip for a curve is something that should be different for everyone," he says. "It's something you have to tinker with until you find something that works. I made up my grip based solely on comfort."

Slider
Faster than the curveball, it moves side to side. "It's a very effective pitch to use with two strikes, and when the batter has already seen my curve," Dunn says. "It's something else for them to think about."

Circle Change
About 10 mph slower than the fastball, the circle changeup moves away from lefty batters. Dunn uses it anywhere in the count. "I use it primarily against lefties," Dunn says. "It's difficult to pick up the difference between the circle change and a fastball, because the rotation looks the same."

Palmball
A pitch that few throw, the palmball is a changeup that drops in the strike zone like a split-finger fastball, but moves about 12 to 15 mph slower. "This is probably the pitch I use least," Dunn says, "but it comes in handy when the batter has already seen my other pitches."
