Oakland, CA (SportsNetwork.com) - The roars at Oracle Arena seemingly grew louder and louder as each Golden State 3-pointer splashed through the net.

Especially when Klay Thompson's four-point play went down as the Warriors poured it on in the fourth quarter.

Thompson netted 21 points, Stephen Curry knocked down six of the Warriors' 14 3s and Golden State routed the Memphis Grizzlies 98-78 to take a 3-2 series lead in Game 5 of their Western Conference semifinal.

The NBA MVP Curry followed up his scintillating Game 4 showing with another dazzling display, scoring 18 points to go with seven rebounds and five assists.

"He hasn't been forcing things, he's been allowing things to happen," Warriors coach Steve Kerr said of Curry's last two games.

The Warriors, who led the NBA in 3-point shooting at 39.8 percent during the regular season, made 14-of-30 from beyond the arc in this one.

"We had too many turnovers tonight," Grizzlies coach Dave Joerger said. "They lead to the 3-point shot."

That they did.

Curry forced six steals, continually leading Golden State to easy transition baskets at the other end. The Warriors held a 29-6 margin in fastbreak points. Nineteen points came off 16 Memphis turnovers.

"We sped the game up with our defensive activity," Kerr said.

The Warriors have now shot 45.1 percent (41-of-91) from long distance in their three series wins, while tallying just a 23.1 percent clip (12-of-52) in the two losses. Curry is 14-of-30 on his 3-point tries in the victories and just 4-of-21 in the defeats.

Golden State can wrap up the series Friday in Memphis.

Andre Iguodala scored 16 points and Harrison Barnes supplied 14 in the triumph.

Versatile wing defender Tony Allen missed Wednesday's game with a left hamstring injury. His disruptive defense in Games 2 and 3 helped the Grizzlies take a 2-1 edge in the set.

"The juice that he brings ... We really missed that from Tony tonight," Joerger said.

Marc Gasol provided 18 points, 12 rebounds and six assists, while Zach Randolph added 13 points and 10 boards for the fifth-seeded Grizzlies, who raced out to an early lead.

Randolph made his first four shots from the field, including one from the top of the arc as the Grizzlies led 13-4.

The Warriors, though, closed the opening frame on a 16-2 run.

"That was the key stretch of the game at the end of the first quarter," Kerr said.

Curry nailed a trio of triples during the surge and his step-back in the waning seconds staked the hosts to a 26-25 edge.

Golden State never trailed again.

It used a 13-2 burst during the middle stages of the second to create some distance.

Curry found Thompson for an off-balanced 3-pointer in the right corner, then hit one of his own from the opposite corner with the shot clock running down a short time later to extend the cushion to 49-37.

The Warriors were up 49-41 at the break and pushed the spread to 74-57 after three.

Thompson's four-point play from the right wing gave Golden State its largest lead at 94-70 with 5:10 left.
