The Portland Trail Blazers dealt the San Antonio Spurs their second straight triple-overtime loss in the NBA on Friday.
The Spurs were humbled by the Memphis Grizzlies 117-116 on Wednesday after three extra periods, and were dealt a similar fate by a Damian Lillard-inspired Portland in San Antonio.
Lillard posted a career-high 43 points, including 16 in the additional periods, as the Trail Blazers downed the champions 129-119.
Spurs led by as much as nine points early in the fourth quarter but were taken beyond regulation when Lillard dropped a lay-up in with 1.4 seconds on the clock.
Lillard then blocked Danny Green's attempted buzzer-beating three, before draining a game-tying three - the final score of the first OT period.
Spurs, as they did in the first period, jumped out to a six-point lead in the second OT stanza but again they were reeled in - Dorell Wright and Steve Blake both drained threes to keep Portland in the ball game.
And it was all Portland in what turned out to be the final five-minute period, as they outscored the Spurs 17-7 - Lillard scoring nine of the first 11 points to see the Trail Blazers to a gutsy victory.
Tim Duncan (32 points, 10 rebounds) and Green (27, 10) had solid games for Gregg Popovich's side, while LaMarcus Aldridge (32, 16) was Lillard's main supporter.
The Washington Wizards made it six wins in succession, edging the Miami Heat 105-103.
John Wall (20 points, 10 assists) and Nene (20 points) helped the Wizards to their 11th win in 12, and seeing them consolidate second spot in the Eastern Conference.
Top spot remains the property of the Toronto Raptors, who strung together their fifth straight victory with a 110-100 triumph at the Detroit Pistons.
Jonas Valanciunas (17 points, seven rebounds) was among the Raptors' best, as the Pistons fell to a 12th straight home loss.
Mike Miller shot seven threes from eight attempts on return from concussion, and LeBron James scored 22 as the Cleveland Cavaliers beat the Brooklyn Nets 95-91.
The Denver Nuggets dealt the Los Angeles Clippers a 109-106 loss, while the Chicago Bulls tempered the Western Conference's second-place Memphis Grizzlies 103-97.
Kobe Bryant went three-from-15, including missing the potential match-winner at the death, as the Los Angeles Lakers lost 104-103 to the Oklahoma City Thunder.
Three straight wins for the Boston Celtics have taken them into eighth in the East, the most recent of which a 114-98 victory over the Minnesota Timberwolves.
The Charlotte Hornets beat the Philadelphia 76ers and the Utah Jazz were triumphant 101-94 over the Orlando Magic.
