Every NBA Playoff Single-Game Blocks Record: The Complete List

Published May 9, 2026 · Updated May 21, 2026 · By The Basketball Fans Editors

NBA playoff single-game blocking records are rare documents. Regular-season box scores from the 1970s and early 1980s are incomplete, blocks weren’t officially tracked until 1973–74, and playoff records from that era have gaps. What follows is the most complete picture the available data supports, verified against Basketball-Reference and StatMuse as of May 2026.

On May 5, 2026, Victor Wembanyama blocked 12 shots in Game 1 of the Western Conference Semifinals between the San Antonio Spurs and the Minnesota Timberwolves. It is the new record. The previous mark of 10, held jointly by Andrew Bynum, Hakeem Olajuwon, and Mark Eaton, had stood as the ceiling since the 1980s.

The complete ranking: top single-game playoff block performances

Note: Pre-1974 games do not have official block statistics. Games from 1974–1982 may have incomplete box scores in some databases. The rankings above reflect verified records from Basketball-Reference and StatMuse as of May 2026.

The record holders, game by game

Victor Wembanyama: 12 blocks (2026)

Game: WC Semifinals, Game 1. San Antonio Spurs vs. Minnesota Timberwolves. May 5, 2026, at Frost Bank Center.

Full stat line: 11 points (5-17 FG, 0-8 3PT), 15 rebounds, 12 blocks.

Result: Spurs lost 104–102.

Wembanyama blocked 12 in a game the Spurs lost by two. Anthony Edwards returned from a knee injury for Minnesota and scored 18. Julius Randle led the Timberwolves with 21 points and 10 rebounds. The blocks record was achieved in the context of a defensive scheme that funneled nearly every Wolves drive into the paint. The success of that scheme was real; the offensive consequences for Wembanyama were also real.

Andrew Bynum: 10 blocks (2012)

Game: First Round, 2012 NBA Playoffs. Los Angeles Lakers vs. Denver Nuggets.

Context: Bynum was 24 and in his best individual season, averaging 18.7 points and 11.8 rebounds in the 2011–12 regular season. The first-round series against Denver was a five-game Lakers win. His 10-block game tied Eaton’s 1985 record, which had stood for 27 years.

Bynum’s career was derailed by knee injuries before he could build on that postseason. He played effectively for only one more season before losing availability and eventually retiring at 28. His share of the record is a footnote to a career that promised far more than it delivered.

Hakeem Olajuwon: 10 blocks (1990s)

Context: Olajuwon reached the 10-block plateau at least once in his peak Houston years. His playoff blocking career produced multiple games in the 7–9 range, and the 10-block game tied Eaton’s record during the period when the Rockets were Western Conference contenders.

Olajuwon’s shot-blocking came from technique rather than wingspan. He was 6’10”, large but not unusually so by the standards of centers who preceded him. What he had was anticipation: he read where a shooter’s release was going before the shot went up, and he was already repositioning as the ball left the shooter’s hand. The 10-block game was the peak of a postseason career that produced first-ballot Hall of Fame blocking numbers over 17 playoff runs.

Mark Eaton: 10 blocks (1985)

Game: First Round, 1985 NBA Playoffs. Utah Jazz vs. Dallas Mavericks.

Context: Eaton was 6’11” and 290 pounds, one of the physical extremes of the modern big-man profile in an era before seven-footers who could move like Wembanyama existed. He led the league in blocks four times, set the regular-season single-season blocks-per-game record (5.56 in 1984–85, never matched), and was the 1985 Defensive Player of the Year.

The Dallas series was a first-round matchup in a best-of-five format (the NBA used best-of-five in the first round through 1986). Eaton’s 10-block game came in a series the Jazz ultimately lost in five games despite his presence.

His record held for 27 years. Bynum and Olajuwon matched it. Wembanyama broke it.

What 12 actually means

The natural question about Wembanyama’s 12-block game is: is this the kind of number that can happen again? Or is it a one-off, a function of a specific opponent, a specific defensive scheme, and a specific night when everything collapsed on the basket in a way that inflates a single player’s block total?

The honest answer is: both.

Any 10+ block game in playoff history has relied on a defensive scheme that concentrated drives toward the paint. You don’t get 12 blocks in an open-court game. The Spurs built their Game 1 defensive plan explicitly around funneling Minnesota into the paint where Wembanyama could contest. They did it on the theory that if they could hold the Timberwolves to a below-average shooting night, 12 blocks and a Wembanyama that goes 5-of-17 from the field might still produce a win. It didn’t, because San Antonio’s own offense was cold.

But Wembanyama at 22 can produce those individual block totals in a way that no other player in the league can right now. His 7’4” wingspan and his ability to leave the ground and reset laterally, the thing that separates elite shot-blockers from merely good ones, gives him the mechanical capacity to block 12 shots in a game. He’s the only player in the current league about whom that statement is true.

He also scored 11 points and shot 0-for-8 from three. You get one or the other, most nights. He’ll need both at some point to take San Antonio where they want to go.

What physical traits produce a 10-plus block game

Every player on this list shares a specific combination of traits. None of them has any one trait by accident.

Raw height, 6’10” minimum. There are no great shot-blockers below 6’8”, and most of the records in the 8-plus range were set by players 7’0” or taller. Longer arms from a taller frame means more vertical space protected at the rim. Eaton at 6’11” and 290 pounds was nearly immovable in the paint. Wembanyama at 7’4” with an 8-foot wingspan can protect a wider coverage zone than any previous record holder.

Timing, not jumping. The best shot-blockers in playoff history are not primarily elite leapers. Hakeem Olajuwon was a good athlete but not an above-average jumper by NBA standards. What he had was anticipation: reading the shooter’s wind-up before the release, leaving the ground in the right direction at the right time. Dikembe Mutombo, career average of 2.9 blocks per playoff game, had limited vertical leaping ability late in his career and still blocked shots at a high rate because he read angles. Wembanyama combines both. He is an above-average leaper for his size and he reads offensive patterns the way older blockers did, which is why his block total in the May 5 game included several contested mid-range attempts where he was already repositioning as the ball came off the shooter’s hand.

Scheme fit. Mark Eaton’s 10-block game in 1985 was set in a Utah Jazz system built around him. Head coach Frank Layden’s defensive scheme from that era funneled every drive directly at Eaton on the weak side, a design that inflated his block opportunities relative to a center operating in a more switching-heavy scheme. The same principle applies to Wembanyama in 2026. Head coach Gregg Popovich’s successor on the Spurs bench constructed the Game 1 Minnesota plan around getting Wembanyama into high-percentage contest positions on every drive. Twelve blocks don’t happen in an open scheme where the center is asked to switch three positions out to the perimeter. They happen when the defensive architecture is built to make them happen.

Career leaders: playoff blocks per game (minimum 30 games)

Wembanyama’s 2026 postseason blocks rate, if extrapolated, would be the highest in NBA history by a margin that is not close. That rate will not hold over 40–50 playoff games. What we don’t know yet is where it settles. If he finishes his career at Olajuwon’s level, 3.74 per game across 145 playoff games, he will be the greatest postseason shot-blocker in NBA history. That is not a safe prediction. It is the direction the data points.
