Russell Westbrook posted a second consecutive triple-double of 25 points, 12 rebounds and 14 assists, while Davis scored 24 points and claimed 13 rebounds at Staples Center.
Malik Monk also played a big hand, finishing with a team-high 27 points - including five of the Lakers' eight points in overtime as they moved to 7-5.
Justin Reaves and Rajon Rondo (both hamstring) joined LeBron James (abdominal strain) on a lengthy Lakers injury list, but Davis says confidence is building in adversity following a second straight overtime win.
"Trying to find ways to get wins while everyone is getting back healthy," Davis said.
"The last two games have definitely been fun. Guys are having fun. Guys are starting to realise how good of a team we are."
Monk relished the opportunity to make a big impact after starting on the bench.
"I had this role a couple of times last year in Charlotte, the year before that when a lot of guys get hurt and I had to come in and play big minutes and facilitate and do other things that I normally don't do," he said.
"But I work on my game a lot, so I was really prepared for this moment."
Lakers coach Frank Vogel revealed that Reaves and Rondo had only suffered minor injuries and are both day-to-day.
Double-doubles from Bam Adebayo (28 points, 10 rebounds, six steals and four assists) and Kyle Lowry (18 points and 11 assists) were in vain for the Heat (7-4), who lost Jimmy Butler due to a sprained ankle.
Giannis Antetokounmpo scored 33 points and Damian Lillard added 32 to help the Bucks win East Group B with a 4-0 record.
Milwaukee will host wild-card New York on either Dec. 4 or 5, with East Group C winner Boston going to Group A winner Indiana for the other quarterfinal before the Final Four in Las Vegas.
Miami, which was without second-leading scorer Jimmy Butler, dropped its second straight following a 9-1 stretch.
Bam Adebayo scored 31 points and Kyle Lowry had 21, including a 3-pointer with 3:25 remaining to put the Heat up 118-115.
The Bucks, though, finished on a 16-6 run, going 5 for 6 from the field and 5 for 5 from the line. Lillard made two free throws with 63 seconds to play to help put it out of reach.
Milwaukee lost forward Pat Connaughton to a sprained right ankle in the second quarter.
Kings rally past Warriors to advance
Malik Monk sank a fadeaway with 7 seconds remaining and the Sacramento Kings rallied from 11 down in the fourth quarter for a 124-123 win over the Golden State Warriors.
De’Aaron Fox scored 29 points and Monk and Kevin Huerter each added 21 for the Kings, who won their group with a 4-0 record and will host New Orleans next week in the quarterfinals.
Sacramento needed a win or a loss by 11 points or fewer to advance but erased a 21-point deficit to win for the seventh time in nine games.
Stephen Curry and Andrew Wiggins led the Warriors with 29 points apiece, but Golden State dropped to 2-8 in its last 10 games.
Timberwolves star Edwards injured in win
Rudy Gobert had 17 points, 16 rebounds and four blocks as the Minnesota Timberwolves overcame an injury to star guard Anthony Edwards in a 106-103 victory over the Oklahoma City Thunder in the In-Season Tournament.
Edwards had 12 of his 21 points in the third quarter before landing hard on his right side during a dunk attempt and leaving with a bruised right hip.
Coach Chris Finch had no more details on the injury or whether Edwards would miss time.
Shai Gilgeous-Alexander led the Thunder with 32 points on 13-of-22 shooting but his 37-foot try at the buzzer, his only 3-point attempt of the night, was well off the mark.
Reserve Troy Brown Jr. scored 17 points and Naz Reid added 15 for Minnesota, which improved the West’s best record to 12-4.
Kevin Durant, who finished with a game-high 35 points, missed his turn-around jumper but O'Neale was on hand with a tip-in to help the Nets snap their two-game skid.
Durant went 13-of-22 from the field with eight rebounds, three assists and a block, clocking up his 26,000th career NBA point along the way, becoming the 19th player to achieve that feat.
The Nets got strong contributions off the bench as Yuta Watanabe added 20 points with seven rebounds, while Ben Simmons had a double-double with 15 points, 13 rebounds and seven assists.
Game-winner O'Neale, who was in the starting line-up, had 11 points, 10 rebounds and 11 assists for the game.
The victory comes after Durant's stinging public criticism of the Nets' starting quality in the continued absence of the suspended Kyrie Irving, who may return for Sunday's game with the Memphis Grizzlies.
Damian Lillard top scored for Portland, who fall to 10-5, with 25 points along with 11 assists. Anfernee Simons added 24 points and Jusuf Nurkic had 17, including a three-point play to tie the game up with 6.5 seconds to go.
Kawhi returns as Clippers shoot down Pistons
Kawhi Leonard had minimal impact on his return after 12 games out as the Los Angeles Clippers rallied from a 12-point deficit to win 96-91 over the Detroit Pistons.
Leonard scored six points with five rebounds and four assists after not playing since October 24 due to knee stiffness. The two-time NBA Finals MVP, who was in the starting lineup, shot two-of-eight from the field.
Reggie Jackson scored a team-high 23 points in a low-scoring game, while Ivica Zubac pulled down 18 rebounds with nine points.

The Kings' five-game win streak is their first since the 2020-21 season, while it comes after they started the season 0-4, winning eight of their past 10 games.
Bennedict Mathurin added 16 points and Obi Toppin and Bruce Brown each added 15 as Indiana beat Central-leading Milwaukee for the second time in three days and improved to 4-1 in the season series.
Giannis Antetokounmpo had 26 points, 11 rebounds and eight assists, while Damian Lillard had 23 points with five assists. Milwaukee has lost two straight for the first time since Nov. 9 and 11.
The Pacers entered the third quarter trailing 68-66 but went on a 21-6 run – capped by Haliburton’s 3-pointer – and opened a 113-97 lead after the period.
The Bucks couldn’t get closer than 10 points the rest of the way.
Surging Clippers cool Suns
Paul George scored 33 points and Kawhi Leonard added 30 as the Los Angeles Clippers won their fourth straight game, 131-122 over the Phoenix Suns.

Devin Booker scored 35 points on 11-of-15 shooting and Bradley Beal added 21 but just 7 of 20 and missed all six of his 3-point attempts.
Kevin Durant missed his second straight game due to soreness in his right hamstring and the Suns had a four-game winning streak stopped.
Kings outlast Magic in double overtime
Malik Monk and Keegan Murray hit 3-pointers in the second overtime and the Sacramento Kings overcame a franchise-record 25 3-pointers by the Orlando Magic in a 138-135 win.
Monk finished with season highs of 37 points and seven 3-pointers and Murray had 31 points on 14-of-22 shooting with 11 rebounds. Domantas Sabonis notched his seventh triple-double of the season with 22 points, 23 rebounds and 12 assists.
Paolo Banchero scored a career-high 43 points with six 3-pointers to lead Orlando but missed a potential tying 3 at the final buzzer.
Jalen Suggs added 24 points, including six 3s, for the Magic.
Deft scoring guard Malik Monk agreed to remain with the Kings on a four-year, $78million contract, ESPN’s Adrian Wojnarowski reported late Thursday night.
The last year of the deal reportedly carries a player option.
Monk set career highs last season by averaging 15.4 points and 5.1 assists while finishing second in Sixth Man of the Year award voting.
Monk, a seven-year veteran out of Kentucky, was due to be an unrestricted free agent on June 30.
Monk had been linked to several teams searching for an infusion of perimeter scoring in free agency, including the Philadelphia 76ers and the Orlando Magic, but those clubs will now need to look elsewhere.
Monk has averaged 11.6 points, 2.5 rebounds and 2.8 assists in 458 career NBA games.
While the Kings have yet to win a play-off series since 2004, Sacramento have strung together back-to-back winning seasons for the first time since 2004-06. In 2023, the club ended a 16-year post-season drought and forced the defending champion Golden State Warriors to a Game 7 in their first-round play-off series loss.
