Basketball Roundup - NYTimes.com The Spurs grabbed a 3-0 lead in the Western Conference finals and now have won five straight this postseason. With the memory of blowing a 2-0 lead a year ago in the Western finals to Oklahoma City, when they lost the next four, the Spurs shook off their sloppy play early and pushed the young Grizzlies to the edge of elimination. San Antonio, which did not lead until the opening minute of the fourth quarter, can wrap up the series Monday in Memphis and get back to the finals for the first time since their last title, in 2007. The Spurs hit 8 of their 10 shots in overtime, with Duncan scoring 7 of his 24 points. Tony Parker had 5 of his 26 in overtime, and even Tiago Splitter, playing with four fouls, scored 6 in the extra five minutes to finish with 11. Mike Conley led Memphis with 20 points. Marc Gasol had 16 points and 14 rebounds, Zach Randolph added 14 and 15, and Quincy Pondexter had 15 points. But the Grizzlies, who thrived at the free-throw line in knocking off No. 1 seed Oklahoma City in the semifinals, got there only 18 times and made only 10. The Grizzlies last led, 85-84, with 1 minute 4 seconds left in regulation on a 15-footer by Gasol. After that, they managed only to tie it up twice, the last on a layup by Randolph with 4:28 left in overtime. Duncan scored and knocked down a free throw with 4:10 remaining to put the Spurs ahead to stay. The Spurs dominated the Grizzlies in the paint, outscoring Memphis by 58-42 to offset their 17 turnovers, which the Grizzlies turned into 25 points. After the Grizzlies outscored San Antonio in the first quarter, the Spurs outscored them in each of the final three periods and overtime, where they had an 18-7 edge to put away the win. Memphis, which had a lead for only 90 seconds in San Antonio, opened up with its trademark gritty defense, forcing eight turnovers in the first quarter to grab an 18-point lead. The Spurs stopped turning the ball over and whittled away that lead to set up a doozy of a fourth quarter, in which the teams swapped the lead 11 times with 10 ties - all in the final 17 minutes. With neither team leading by more than 2 in the final eight minutes of regulation, fans stayed on their feet, holding their "Believe Memphis" towels and trying to will the Grizzlies to another win. Manu Ginobili scored 7 points in the quarter, and he put the Spurs back up first with a layup with 1:19 left and then a pair of free throws with 54.5 seconds remaining. But Ginobili also picked up his fourth foul, giving Tony Allen a chance to split free throws and tie the score for the ninth time. Ginobili then missed a 3-pointer with 20.9 seconds left, with Allen getting the rebound. Memphis set up for the final shot, but Conley missed on a runner at the buzzer. With the Spurs taking control in their second straight overtime win in this series, they pushed their lead to as much as 11 down the stretch and sent fans heading toward the exits. The Grizzlies lost for the first time at home this postseason and just their second since Feb. 8. Conley, who led the N.B.A. in steals this season, set the tone with a steal on the Spurs" first possession. Parker, who set a career high in the postseason with 18 assists in Game 2, had four turnovers in the first quarter and finished with seven. San Antonio turned it over eight times, with the Grizzlies stealing seven of those in the first, the last with 4:53 left, prompting Spurs Coach Gregg Popovich to pull his starters and go with five fresh Spurs.
