Following his 16-point, 12-rebound outing in Wednesday's Game 5 win over the Dallas Mavericks, San Antonio Spurs forward Tim Duncan now boasts 151 career playoff double-doubles, putting him just six shy of the NBA record of 157 held by former Los Angeles Lakers point guard Magic Johnson, per NBA Stats.

Duncan claimed second place during last season's Western Conference Finals, when his 24 points and 10 rebounds in Game 3 against the Memphis Grizzlies pushed him ahead of ex-Laker Wilt Chamberlain's 143 postseason double-doubles.

Rounding out the top five for playoff double-doubles are Duncan's former foe Shaquille O'Neal (142) and the great Bill Russell (137).

While Russell, O'Neal, Chamberlain, and Duncan almost exclusively earned their respective rankings via the point-rebound variety of the double-double, Johnson's leading total includes a healthy mixture of point-rebound and point-assist performances.

Per Yahoo! Sports, Johnson also holds the record for most career triple-doubles in the playoffs, with his 30 easily tops in league history. Duncan has just four playoff triple-doubles to his name, while the Miami Heat's LeBron James leads all active players with 11.

Nonetheless, the 38-year-old Duncan is edging closer to Johnson's mark, and since Wednesday's victory put the Spurs one win away from advancing to the second round, Duncan's window to clinch the record could very well be extended.

With that in mind, the man widely considered to be the greatest power forward in NBA history may be able to pass Johnson this postseason.
