INDIANAPOLIS (AP) -- Rookies Brandon Rush and Roy Hibbert continue to put up big numbers for the Indiana Pacers.
Rush had 17 points and five rebounds, and Hibbert added 12 points, 12 rebounds and four blocks, leading the Pacers to a 112-86 preseason victory over the Memphis Grizzlies on Friday night.
"Coach (Jim O'Brien) put us out there for a reason -- he believes in us -- and we're going to do everything we can to hold up our part," Hibbert said. "We're adjusting as quickly as possible and trying to do it smoothly."
With nine new players competing for roster spots, the Pacers have gotten a boost from their two first-round draft picks.
"I've been very impressed with both of them," said veteran center Jeff Foster. "They're putting up great numbers now and hopefully they can contribute during the season."
Stephen Graham had 16 points, Danny Granger scored 12 and T.J. Ford chipped in 11 for the Pacers, who improved to 3-2 in the preseason.
"I think we're playing well right now," Rush said. "It's definitely important for us to get off to a good start and carry that on to the regular season."
Rudy Gay had 19 points, rookie O.J. Mayo scored 17 and Hakim Warrick 10 as Grizzlies dropped to 2-4 in the preseason.
"We have too many guys going one-on-one and holding the ball," Memphis coach Marc Iavaroni said. "We need to play harder and smarter as a team."
Indiana jumped out to an early 22-11 lead on Rasho Nesterovic's basket, but Memphis shot 58 percent from the field in the first quarter and closed the gap to 27-26 on Gay's jumper.
The Pacers, who briefly trailed 31-29, built their lead back up to 11 points after Ford's jumper late in the first half. Graham had eight points in the second quarter.
Indiana used an 11-0 run in the third to open a 68-49 advantage, and Hibbert's basket later in the quarter gave the Pacers a commanding 78-54 lead.
"We have a ways to go, but I think we're meshing really well," Hibbert said.
It was the second meeting between Indiana and Memphis in four days. The Grizzlies beat the Pacers 103-95 in Memphis on Monday.
Indiana guard Mike Dunleavy made his preseason debut, scoring nine points in 12 minutes. He missed the team's first four games and most of training camp with a sore right knee. "Mike played well," O'Brien said. "We really flow with him." ... Pacers G Travis Diener (sore left foot) and F Troy Murphy (sore left Achilles') did not play. ... Rush and Grizzlies F Darrell Arthur were back on the court together after leading Kansas to the NCAA championship last season. ... Memphis G Mike Conley returned to his hometown of Indianapolis, where he starred at nearby Lawrence North High School.
