two-seam fastball
Tailing hard throw
A two-seam fastball is a baseball pitch gripped along the ball's narrow seams rather than across them.
The grip produces more movement than a four-seam fastball—typically sinking or tailing toward the pitcher's arm side—at the cost of some velocity.
Pitchers use it to induce ground balls: His two-seamer got the double play.
