In baseball, a slide is the action of a player, acting as a baserunner, who drops his body to the ground once he is very close to the base he is approaching and slides along the ground to reach the base.

A baserunner may slide into base in a number of different ways and for a number of perceived reasons, including to avoid a tag out, to avoid overrunning the base, and to interfere with the defensive player protecting the base. Players should determine whether they will benefit by sliding in a particular game situation, and whether an increased risk of injury will make a slide worthwhile.

Methods of sliding

There are many different ways to slide, involving different ways of attempting to avoid the tag, reaching to touch the base, and/or trying to contact the defensive player. Players generally slide feet-first, but sometimes also use a head-first technique. Since the defense generally expects a slide, sometimes a baserunner trying to avoid being tagged out will not slide directly towards the base, but rather to a side away from where the ball is coming, and then reach back to touch the base.

Reasons for sliding

Avoiding a tag out

On plays in which the baserunner may be tagged out by the opposing defensive player covering the base, the baserunner's body being down on the ground presents the lowest profile target for the defensive player to tag. This makes it slightly more difficult for the defensive player to apply the tag in time to put out the baserunner.

Avoiding overrunning the base

In most cases, it is important that a baserunner's momentum from running is not so great at the time of reaching the base that it would cause the baserunner subsequently to overrun the base, placing him in jeopardy of being tagged out once contact with the base is lost. This need to reduce the momentum from running is directly at odds with the need to reach the base as quickly as possible in the first place. Sliding addresses this problem by providing, through the body's friction with the ground, the most rapid means of slowing a baserunner's momentum. This, in turn, allows the baserunner to remain at top speed for as long as possible before needing to initiate slowing.

Interfering with the defensive player (take-out slide)

Sliding can sometimes be used as a means of interfering with the play of the opposing defensive player who is covering the base being approached. For example, when it is possible that a double play might occur, and the baserunner approaching second base has already been put out, he might still try to slide toward the defensive player who intends to throw the ball to first base. If the defensive player moves away from second base as he prepares to throw the ball toward first, the baserunner may still slide directly toward the defensive player, even though that means sliding away from second base itself. This has the effect of hampering that defensive player's ability to complete the play, either directly by making physical contact with him, or indirectly by distracting him by making him fearful of such contact. A slide performed exclusively for the purpose of hampering the play of the defense is called a "take-out slide".

Whether a particular instance of a take-out slide is legal within the rules of baseball is a judgement call made by the umpire, usually based upon how close the baserunner comes to the base they are approaching during the slide. If a baserunner strays too far from the base when attempting a take-out slide, the umpire may declare the slide to be an example of illegal interference and call an extra out. As a general (but not absolute) guideline, even if the baserunner clearly slides toward the defensive player and away from the base, so long as the baserunner comes close enough to the base that he is able to touch it with some part of his body during the slide, the slide will be ruled to be legal. On the flip side, the fielder will often be granted the neighborhood play under such circumstances.

Speed impact of sliding

The television series MythBusters tested participants' baserunning speed with and without sliding, and found that in cases where the runner need to stop on the base, sliding into that base instead of staying upright provided a split second of advantage, suggesting the more rapid deceleration as the key. However, when removing the need to stop, the general belief within baseball circles is that remaining upright and running all the way to the base at top speed allows a baserunner to reach the base faster than sliding. Consequently, on plays during which neither being tagged out nor being put in jeopardy by overrunning the base is at issue (e.g., when approaching first base after having batted the ball), players are usually advised not to slide.[1] Nonetheless, this conventional wisdom is not universally accepted, and as such, some players may feel that sliding will get them to the base more quickly and will thus choose to do so despite advice to the contrary.

Risks associated with sliding

One study in the American Journal of Sports Medicine followed seven softball and three baseball teams in Division I of the NCAA, and found the overall incidence of injuries sustained while sliding was 9.51 per 1000 slides. Softball players had about twice the incidence of sliding injuries as baseball players in the study. 11% (four out of 37) of the injuries caused the player to miss more than 7 days of participation.[1]

Because baseball shoes are spiked on the bottom, sliding with the spikes up increases the probability of injury to the defensive player covering the base. Knowledge of this fact can often increase the defensive player's fear of the possible contact from an impending slide and thus increase his distraction while attempting to make a play. Ty Cobb was well known for actually sharpening his spikes in the dugout, in full view of the other team, in order to intimidate their players.[citation needed] Cobb developed nine different ways to slide into base.[2]

Other uses

The baseball slide is a move used in professional wrestling as a variation on the dropkick maneuver. It closely resembles and is based on the standard feet-first baseball slide. It involves the wrestler running and sliding feet first, with the usual aim being to kick the opponent with both feet.
