Slider

Slider ( engl: actually slide, but in this context without direct translation ) refers to a specific Wurfart the pitcher in baseball sport.

The slider is one of the "Breaking Balls", the litters off or aborting trajectory. It is located on trajectory and velocity between the fastball and curveball. He is thrown slightly slower than the fastball, but gets by the uneven handle next to a small reverse rotation mainly a lateral rotation (note adjacent picture). While this is not as strong as the curveball, but the slider is thrown faster and has therefore over that a weaker curvature of the trajectory on. In comparison to the regular ballistic trajectory is caused by the Magnus effect a lateral breaking and greater downward movement of the ball. The first ball flies like a fastball and breaks through the spin just before the batter from the expected straight flight path from. Since the rate is only slightly lower compared to the fastball, it is therefore difficult to assess from the batsman. Compared to similar Cutter Slider breaks out stronger.

Because the movement stronger deviate in Slider from the natural union stance as for example in the fastball, are violations of the throwing arm at pitchers who run this throw, more often than in pure fastball throwers.

As a pitcher with an effective slider John Smoltz is known. His throw at first looks as if he would meet the strike zone, but stops just before out of the zone. This often leads to " Swingin 'a miss", the passage Swing by the batsman.

History

Is not entirely clear whether Chief Bender the "inventor" of the slider was, it is documented in any case that he regularly as one of the first started this pitch .. He called it at that time the "nickel change". With the help of the slider he threw on May 12, 1910 a no-hitter.
