The spike curve

[jamesh23]

what is this pitch exactly I would like to throw it, some places I hear its a knuckle curve, and others I hear you hold it like a 4 seamer, but curl in your index and middle finger, then throw it hard like a fastball, and kinda push so you get a downward spin

so how do you throw it? and whats its action? 12-6? should it be thrown slow or hard?

I played with it overhand, pitched it underhand in fps throwing it at every speed. When it's right it's right. When it doesn't show up for the game, check footwork and how your rear toe times off the ground... how that happens can coordinate with the forefinger-tip's action in twirling as the ball leaves. That fingertip twirls the ball extra as it leaves, and it twirls best when that dragging toe helps out. Maybe it jerks the hand.

You can get too involved in wrist turns or grips when the right medicine is in the toe. A toe-drag timed to brake that finger tip pulls it a little quicker off the ball. Hops-up the spin.

It can break like crazy at every speed when it's right; can be made to break early, late, sharp, jughandle; up a hair, down, or variations between depending on hand angle at release, grip and wrist tension. Same pitch appears to be a repertoire when it's going right- baffles them with b-s.

You described a knuckleball. You only bend the index finger and keep the middle finger gripping the ball to impart spin. You throw it just like a regular curveball with your hand already supinated.

A number of MLB pitchers use this grip. Phil Hughes and Roy Oswalt throw it slow in the low 70's. Dan Haren, Joel Zumaya, Justin Velander, A.J. Burnett, and Bobby Jenks throw it as a power curve in the low 80's. Some other guys that use this grip are Pedro Martinez, Joe Smith, and Mike Mussina.

who's the guy in the thunder uniform?

also what are the Pros/cons of throwing a K-curve, instead of a normal curve?

and no I seen a thing on college baseball during last years world series I believe where they showed this guy who threw his curve like mike mussina they said and they called it a spike curve and he held it like a knuckle ball but when he threw it he flicked the 2 top fingers to get as much down spin as possible.

Yeah, xv4 is right. I described a forefinger-knuckle -push pitch.
