How to throw the Vulcan change up.
The Vulcan change up is a pitch thrown between the middle and ring fingers on the pitching hand. The name comes from Mr. Spock, for those of you Trekkies out there, whereby he had a greeting where he would part those fingers.
Most recently, Eric Gagne, dominant closer for the Los Angeles Dodgers, threw a Vulcan change up, as has Ian Kennedy in recent years. Both pitchers were quoted as saying that they got more movement on the ball and felt more comfortable delivering this pitch than a traditional change up.
I would caution young pitchers from spending too much time learning the Vulcan change up. But rather, learn the three-finger trophy change or the circle change up before fiddling around with this more gimmicky change up grip.
