Josh Green has recorded his first double-double of the NBA season but could not prevent the Memphis Grizzlies from running out 112-108 winners over his Dallas Mavericks.

Green, who along with Josh Giddey has been the most consistent Australian NBA player this season, was in for a test on Sunday (AEDT) when Dallas met conference heavyweights Memphis without injured stars Kyrie Irving (foot) and Luka Doncic (thigh).

Ranked third in the west, the Grizzlies had the better of the first half before Green and Jaden Hardy orchestrated a 33-21 third period - all the more impressive given Memphis average more points in the third quarter than any other term.

Green had 15 second-half points and gave the Mavericks their biggest lead of the night - 11 points - with a three-pointer that forced a Memphis timeout just after the final change.

But with their own superstar Ja Morant out indefinitely, the Grizzlies bench rallied. David Roddy finished the night with 24 points, the most for a Grizzlies bench player this season.

Green had a chance to put the Mavericks back within one point in the final 25 seconds but his three-point attempt bounced off the rim and Memphis held on.

The Australian swingman finished with 21 points and a team-high 10 rebounds, confirming the second double-double of his 171-game NBA career.

The loss continues a turbulent run of form for the Mavericks, who have not won back-to-back games or tasted victory on the road in a month.

Australian veteran Joe Ingles had his best shooting night of the season as the Milwaukee Bucks fell victim to an ambush by Steph Curry and the Golden State Warriors in overtime.

Ingles was the Utah Jazz's all-time leader in three-pointers before joining the Bucks this season and hit all five of his attempts from long range to finish with 15 points and seven assists.

The Australian was one of seven Bucks to finish in double figures for points but none could outdo Curry, who had nine of the Warriors' 14 points in overtime to confirm a 125-116 win.

"Overtime and fourth quarter, he got away from us a little bit," Bucks coach Mike Budenholzer said of Curry.

Elsewhere, Giddey came up trumps over Dyson Daniels in a battle of two Australian guards.

Daniels' New Orleans Pelicans and Giddey's Oklahoma City Thunder both came into the clash in need of a win, given they sit just outside the western conference play-in bracket in 11th and 12th place respectively.

But the Thunder were always in control, winning 110-96.

Giddey has improved his shooting significantly in his second NBA season and netted eight of his 12 attempts from the field for a total of 19 points.

"It's hard to hold a lead for the whole game on the road the way we did tonight," Thunder coach Mark Daigneault said.

"We held them off with sound execution on both ends."

Elsewhere, the Orlando Magic upset play-offs hopefuls and intrastate rivals Miami with a 126-114 overtime win.
