SAN FRANCISCO — Golden State entered Friday’s Game 6 at Chase Center with a not-so-quiet confidence.

Even after losing a lopsided Game 5 in Houston, the Warriors assured anyone who would listen that there was nothing to worry about.

The Warriors were led by playoff-tested future Hall of Famers who knew how to close out a series in the Bay Area.

The Warriors looked like veterans, all right – an old team with weary legs that struggled to keep up with the spry Rockets as the visitors defeated Golden State, 115-107.

The Warriors will play in Houston on Sunday at 5:30 p.m.

The turning point was a 14-1 run by Houston in the fourth quarter, putting the Rockets up 106-89.

Before they ran out of gas, the Warriors’ stars played well. Stephen Curry scored 29, and Jimmy Butler put up 27.

But neither shot well in the last 12 minutes, unable to keep up with Fred VanVleet and his 29 points, or the Rockets and their 42 points in the paint, where Alperen Sengun (21 points, 14 rebounds) and Steven Adams (17 points, five rebounds) feasted.

Now the Warriors are just 48 minutes away from blowing a 3-1 series lead for the first time since the infamous 2016 Finals.

The Warriors entered the fourth quarter down by just two but allowed the Rockets to cap a 6-0 run with a tough Jalen Green baseline putback. After the Warriors scored four unanswered points in response, Houston got back on track with a Sengun layup and four points from Thompson.

The Warriors were able to shake Curry open a couple of times, but his shots rimmed out.

On another possession, Butler grabbed a tough rebound but saved it right to VanVleet, who buried his sixth 3-pointer of the night to give Houston a 101-89 lead with seven minutes remaining.

It was that kind of night for the Warriors, who made a spirited push – using the Hack-a-Shaq to send Adams to the line – but just couldn’t close the gap in the end.

Game 6 began with yet another heated moment in a series full of them.

The officials assessed Draymond Green a flagrant foul 3:07 into the game after the Warriors forward struck Rockets guard Jalen Green in the head on a screen.

The Rockets took a 25-21 lead after 12 minutes, keyed by four offensive rebounds and a trapping zone defense that forced five turnovers – three by Curry.

Curry has dealt with a thumb injury for months, and photos recently surfaced showing the appendage severely swollen before Game 5.

The Warriors decided to break out a second-quarter trap of their own but asked the slow-footed Quinten Post to run with VanVleet, something the Rockets guard delighted in as he dribbled right past the defense and picked the Warriors apart.

The Warriors’ offense was stuck in slow motion until Curry made a 3-pointer off a Draymond Green off-ball screen with 3:36 left in the second quarter.

After being hounded by Rockets traps, the Warriors began letting Curry operate in isolation, and that shift produced an 11-point Curry flurry that had the score tied at 46 with two minutes left in the half.

The Rockets responded with a 7-0 run, but Butler ended the half with a preposterous fading 2-pointer with 0.6 seconds left to make the halftime deficit just 53-48.

Butler continued his hot shooting in the third quarter, scoring seven early points as he went on to enjoy his third 20-point game of the playoffs.

The Rockets, led by another efficient shooting night off the bench from Jabari Smith, maintained a multi-possession lead throughout the third quarter.

Kerr opted to use the “Hack-a-Shaq” strategy on Adams, forcing the sub-50% free-throw shooter to take six foul shots. It didn’t work. He made 3 of 6, and Sengun tipped in the final miss to give the Rockets five points in three possessions.

The Warriors finished the quarter strong, though, with Curry shaking free for a signature layup off a Green assist and later making two foul shots to send the Warriors into the fourth quarter down just 86-84.
