SAN ANTONIO -- With the series tied and the aging Spurs struggling to match the energy and level of play of the young Golden State Warriors, San Antonio knew it needed a big game from one of its stars.
Tony Parker provided it, and then some.
Parker had 25 points and 10 assists, leading the Spurs to a 109-91 win over the Warriors on Tuesday night in Game 5 of their Western Conference semifinal series.
With a 3-2 series lead, San Antonio can close out Golden State by winning Game 6 on Thursday in Oakland, Calif.
Tuesday's margin was the largest for either team in a competitive series that has featured two overtime games.
Parker, wearing a black sleeve to protect a left calf that was bruised in Game 3, shot 9-for-16 from the field, 7-for-10 from the free-throw line. He committed just two turnovers.
"He played well. He made everybody better," teammate Manu Ginobili said. "He scored when we needed him to score. He played the way Tony played the whole season. He had a great one, and we needed it."
San Antonio, which gave up an eight-point lead with four minutes left in Game 4 and eventually lost 97-87 in overtime, led 102-84 when Ginobili hit a 3-pointer with 4:02 left Tuesday.
The Spurs shot 40-for-77 (51.9 percent) from the field and 19-for-15 (76 percent) from the foul line. It was a marked improvement from Sunday, when they compiled their worst collective shooting performance from the field (35.5 percent), 3-point arc (29.5 percent) and free-throw line (56 percent) since 1997.
They had 30 assists on 40 field goals in Game 5.
"By far, by far," said Parker when asked if this was the Spurs' best offensive game of the series. "For whatever reason tonight, I got going, Timmy (Duncan) got going in the second half and we made shots. Ball movement was good, so hopefully we can do the same thing at Golden State."
Kawhi Leonard scored 17 points for San Antonio, Danny Green added 16 and Ginobili had 10. Duncan contributed 14 points and 11 rebounds.
The Spurs' defense forced 14 turnovers (11 in the second half) that led to 23 points.
Golden State cut San Antonio's lead to two early in the third quarter, but the Warriors could not gain the momentum from their star players.
San Antonio held the "Splash Brothers" -- Stephen Curry and Klay Thompson -- to a combined 13 points on 6-of-22 shooting from the field.
Curry has struggled since scoring a career playoff-high 44 points in Game 1. He continues to play after spraining his left ankle in Game 3. He finished 4-for-14 for nine points and added eight assists Tuesday.
"I was terrible, plain and simple," Curry said. "They outplayed us as a team. Individually, I didn't have anything on either end. (I was) a step slow, my shot wasn't falling, and I was trying to make plays but defensively I lost a little focus. I have to personally get better. You just have to come back and learn from it."
Harrison Barnes led the Warriors with 25 points, with Jarrett Jack adding 20 and Carl Landry scoring 16.
The Warriors shot 46.7 percent (35-for-75) from the field, 15-for-23 (65.2 percent) from the free-throw line. They connected on only six of their 16 3-point attempts.
"We'll be fine," Warriors coach Mark Jackson said. "We're excited about Game 6. I believe those guys have a lot left in them. They won the ballgame tonight, give them credit. My guys will bounce back."
Barnes led all scorers with 15 through the first two quarters, but it was not enough for the Warriors. The Spurs shot 51 percent from the field to take 54-51 lead into the locker room.
NOTES: Barnes was named NBA All-Rookie first team on Tuesday. Barnes was a first-round draft pick, seventh overall, from North Carolina. "Well-deserved," Jackson said. "Proud of him and one for the good guys. Just a big-time award for him. Great recognition." ... Duncan was selected to the NBA All-Defensive second team. Duncan has been selected to 14 All-Defensive teams in his 16 seasons, which is more than any other player in NBA history. ... Duncan tied Wilt Chamberlin with 143 double-doubles in postseason play, second only to Magic Johnson, who has 157. ... NBA commissioner David Stern attended the game.
