Durant strained his right calf late in the third quarter. The two-time reigning NBA Finals MVP limped to the locker room after landing awkwardly following a baseline jumper. He finished with 22 points, five rebounds and four assists.
James Harden scored 31 points for the Rockets, who will try to stave off elimination back home in Houston on Friday night [Saturday NZT].
Durant's status for Game 6 is unclear. After he departed with the injury, the rest of Golden State's array of stars helped the Warriors close it out.
Draymond Green received his fourth technical of the post-season with 3 min 39 sec left, and then knocked down a 3-pointer on the other end. Thompson followed Green's 3 with one of his own to make it 97-89 with 2:33 remaining.
Stephen Curry struggled with his shot yet again and finished with 25 points on 9-for-23 shooting. He went 3 of 11 from long range.
Curry hit a 3 with 5 min 9 sec to play that made it 89-85. He didn't even score his first points of the night until a 3 4:22 before halftime.
Golden State nearly gave it away with an awful third quarter, when the Warriors managed just 15 points and committed six turnovers. The game was tied at 72 going into the final 12 minutes.
Harden's 3 with 3:07 left in the third trimmed Golden State's lead to 66-62, and then Iman Shumpert made it a one-point game with a 3.
Eric Gordon's layup with 40.6 seconds remaining gave the Rockets their first lead since the early minutes.
Green had eight points, 12 rebounds and 11 assists in another spectacular effort on both ends. He supplied the energy for Golden State after two losses at Houston evened the series.
The Warriors led by as many as 20 but missed open looks and even layups, clanking shots off the front rim and allowing the tough-minded Rockets to stay close.
Then, they heeded Steve Kerr's simple message: "Poise and awareness and poise and patience applies to all of life and not just offence," the coach said beforehand.
The Warriors pulled it off without Durant, whose 35.4 playoff scoring average was best in the NBA coming into the game.
Harden shot 10 for 16 and dished out eight assists. The reigning MVP injured his eyes during the first quarter of Game 2 last Tuesday on a hit by Green as they fought for a rebound. Harden's left eye was still red leading into Game 5.
The Warriors' win guarantees their loyal fans in the East Bay at least one more home game at Oracle Arena before the team moves to new Chase Centre in San Francisco for next season.
Golden State has won each of the three previous layoff meetings against the Rockets during the last five years: the 2015 Western Conference finals, the first round the following year, and last season's West finals by rallying from a 3-2 deficit.
