Inbasketball, ablock orblocked shot occurs when a defensive player legally deflects afield goal attempt from an offensive player to prevent a score. The defender is not allowed to make contact with the offensive player's hand (unless the defender is also in contact with the ball) or afoul is called. In order to be legal, the block must occur while the shot is traveling upward or at its apex. A deflected field goal that is made does not count as a blocked shot and simply counts as a successful field goal attempt for shooter plus the points awarded to the shooting team. For the shooter, a blocked shot is counted as a missed field goal attempt. Also, on a shooting foul, a blocked shot cannot be awarded or counted, even if the player who deflected the field goal attempt is different from the player who committed the foul. If the ball is heading downward when the defender hits it, it is ruled asgoaltending and counts as a made basket. Goaltending is also called if the block is made after the ball bounces on the backboard (NFHS excepted; the NCAA also used this rule until the 2009–10 season).
Nicknames for blocked shots include "rejections", "stuffs", "bushed", "spoinked", "fudged", or “double-fudged" (two-handed blocks), "facials", "swats", "denials", and "packs". Blocked shots were first officially recorded in theNBA during the 1973–74 season.
Largely due to their height and position near the basket,centers andpower forwards tend to record the most blocks, but shorter players with good jumping ability can also be blockers, an example beingDwyane Wade, the shortest player, at 6'4", to record 100 blocked shots in a single season.[1] A player with the ability to block shots can be a positive asset to a team's defense, as they can make it difficult for opposing players to shoot near the basket and, if the blocked shot is kept in play rather than swattedout of bounds, a blocked shot can lead to a fast break, a skillBill Russell was notable for.[2][3] To be a good shot-blocker, a player needs great court sense and timing, and good height or jumping ability. One tactic is that a shot-blocker can intimidate opponents to alter their shots, resulting in a miss.[citation needed]

A chase-down block occurs when a player pursues an opposing player who had run ahead of the defense (as in afast break), and then blocks their shot attempt. Often, the block involves hitting the ball into the backboard as the opponent tries to complete alay-up. One of the most recognized chase-down blocks isDetroit Pistons'Tayshaun Prince's game-saving block onReggie Miller in Game 2 of the2004 NBA Eastern Conference Finals against theIndiana Pacers.[4][5] Pistons announcerFred McLeod, who first witnessed this style of blocks from Prince, created thechase-down term later with theCleveland Cavaliers.[4][5] During the2008–09 NBA season, the Cavaliers began tracking chase-down blocks, creditingLeBron James with 23 that season and 20 the following season.[4][5][6] Another landmark chase-down block occurred in the2016 NBA Finals when LeBron James, in the closing minutes of the 4th quarter delivered what became known as "The Block" on alay-up attempt byAndre Iguodala with the score tied at 89 and 01:50 remaining in the game.[7][8]

Mourning: "I would tell you this. Coach Thompson brought Bill Russell in to speak to me and Dikembe. And he's like, Listen, if you block a shot into the stands, the opposing team does nothing but get the ball back. And he said if you have the ability to block shots, why not keep it inbounds? He said don't swing at it. Direct it. I've never forgotten that."
Cleveland, no matter how hard it may have tried, couldn't forget 'The Drive' or 'The Fumble' or 'The Shot.' But now, thanks to LeBron James, it has a sports moment requiring the definite article that it will want to remember forever: The Block.
