Basketball: Tim Duncan stars again in overtime as Spurs push Grizzlies to the brink

MEMPHIS (AFP) - The San Antonio Spurs shook off a sluggish start and dominated overtime to beat the Memphis Grizzlies 104-93 on Saturday and move within one victory of reaching the National Basketball Association (NBA) finals.

The Spurs posted their second straight overtime triumph to take a commanding 3-0 lead in the best-of-seven Western Conference final series.

The winners of the series will face either the Miami Heat or Indiana Pacers for the NBA title.

The Grizzlies go into Game Four on Monday knowing that, even if they fend off elimination, they face a daunting task. No team have rallied from an 0-3 deficit to win a seven-game NBA play-off series.

San Antonio's veteran star Tim Duncan scored the first five points of overtime. He scored seven of the Spurs' 18 points in the extra session, finishing with 24 points and 10 rebounds.

"He was huge the other night in overtime and he did it again tonight," Spurs coach Gregg Popovich said of Duncan. "That's why he is considered as great as he has been for the last 17 years. He feels responsibility to carry us in those situations, and he did it again tonight."

Point guard Tony Parker scored 26 points and handed out five assists, and Manu Ginobili chipped in 19 points and pulled down seven rebounds as the Spurs rallied from an 18-point first-quarter deficit.

Mike Conley Jr finished with 20 points for the Grizzlies.

"We came out with great energy," Memphis coach Lionel Hollins said. "We just couldn't sustain it. We subbed, tried to get some rest, but we didn't get production from people off the bench and then we couldn't rev it back up when we got back to our starters."
