When Tony Parker started running low on masterful plays, Tim Duncan was there to take over and lead the San Antonio Spurs to a 2-0 lead in the Western Conference finals.

Parker had 15 points and a career playoff-high 18 assists, Duncan scored San Antonio's first six points of overtime, and the host Spurs bounced back after squandering a 13-point lead in the fourth quarter to beat the Memphis Grizzlies 93-89 on Tuesday night.

"I hate that we gave up that big of a lead in that situation," Duncan said. "But we were resilient enough to go to overtime and not let it affect us."

Duncan opened the extra period with a layup and then made a tiebreaking putback on Parker's missed jumper. He added a runner that bounced high off the back iron and rattled in for a 91-87 lead with 1:08 to play.

The Grizzlies had a chance to tie after Jerryd Bayless hit a jumper and Parker missed 1 of 2 free throws with 14.6 seconds left, but Bayless' 3-pointer was off-target.

Memphis has fallen behind in all three playoff series so far, including rallying from an 0-2 deficit in the first round against the Los Angeles Clippers.

"We're in the same boat we were when we left L.A. We've got to take care of business at home," coach Lionel Hollins said. "It's not going to be easy, but that's where we are."

Bayless and Mike Conley each had 18 points to lead Memphis.

Duncan had 17 points and nine rebounds, missing most of the second half with foul trouble.

Lottery: The Cleveland Cavaliers won the lottery for the second time in three years, giving them the No. 1 pick for the June 27 draft. In 2011, the Cavs used the pick to take eventual Rookie of the Year Kyrie Irving.

The Orlando Magic fell back one spot to No. 2, while the Washington Wizards leapt from the No. 8 spot to third. Charlotte fell from No. 2 to fourth.

Phoenix will pick fifth, followed by New Orleans, Sacramento, Detroit, Minnesota, Portland, Philadelphia, Oklahoma City (via Toronto), Dallas, and Utah.
