Jordan Poole proclaimed the Golden State Warriors to be "so lucky" to have Otto Porter Jr after his 40-second heroics against the Houston Rockets.

Porter sunk a trio of three-pointers, made one steal and one rebound all in the penultimate minute of the first half to steer the Warriors back in front during the second quarter.

The former Washington Wizards small forward put up 15 points and nine rebounds in only 18 minutes as the Warriors ran out 120-107 winners to move to a league-best 8-1.

Poole top-scored with 25 points, including shooting seven-of-13 from the field and all nine attempts from the free-throw line, but it was Porter's "huge" contribution that left him most impressed.

"Otto is... we're so lucky to have him," said Poole. "He's a really big threat from the three-point line and he's a mismatch for a lot of fours and fives that guard him, especially on the offensive end.

"Being able to get him going early and seeing him catch a rhythm the way he did was huge."

Coach Steve Kerr said the thrilling second-quarter stretch "had the bench jumping up and down" with excitement.

"Otto and Beli [Nemanja Bjelica] have given us a totally different dimension from anything we've had since I've been here," Kerr said. "Just having two bigs who can shoot threes like that really opens up the floor."

Porter scored 12 of his points in the second quarter just as the 1-9 Rockets had wrestled back control of the contest, recovering from a five-point deficit to move four clear with six and a half minutes left.

The Warriors ended the half 69-61 ahead and never looked back as they won for the fourth game in a row.

"I hit that one in the corner and was just playing good offense," said Porter. "We got some stops. We got some key turnovers, some steals and – we're on defense creates offense – I was able to get a few looks and knock it down.

"We always preach, 'Finish in the quarter'. Going into half-time, that was a big moment in the game where the energy shifted towards us. Like coach said, we've just got to continue to find ways to finish quarters."
