The Memphis Grizzlies did not follow the script in their shock 112-109 victory over the top-ranked Utah Jazz in the NBA playoffs, while the Philadelphia 76ers and Phoenix Suns drew first blood in their first-round openers.

Utah secured sole possession of the best record in the NBA for the first time in franchise history, having topped the Western Conference with a 52-20 record.

But in the continued absence of All-Star Donovan Mitchell (ankle), the Jazz were upstaged by the eighth-seeded Grizzlies in Sunday's opener on home court.

Dillon Brooks (31 points), Ja Morant (26 points) and Jonas Valanciunas (15 points and 13 rebounds) fuelled the visiting Grizzlies in Utah.

Brooks became the sixth player in the last 10 postseasons to score 30-plus points in his playoffs debut, joining Devin Booker (2021), Luka Doncic (2020), Kyrie Irving (2015), Anthony Davis (2015) and Damian Lillard (2014).

Kyle Anderson also registered a Grizzlies single-game playoff record with his six steals, surpassing the previous mark set by Mike Conley – who now plays for the Jazz – in 2013.

The Jazz were led by Bojan Bogdanovic (29 points), Conley (22 points and 11 assists) and Rudy Gobert (11 points and 15 rebounds).

Harris and Embiid flex muscles, Booker stars as Suns sizzle

Eastern Conference top seeds the 76ers overcame the Washington Wizards 125-118 in Game 1 of their first-round series. A playoff career-high 37 points from Tobias Harris set the tone, while MVP hopeful Joel Embiid had 30 points, six rebounds and three assists. Harris and Embiid became the first pair of 76ers to score 30-plus points in a playoff game in 31 years since Charles Barkley and Hersey Hawkins. All-Star team-mate Ben Simmons (six points, 15 rebounds and 15 assists) joined Hall of Famer Wilt Chamberlain as the only 76ers players ever with 15 rebounds and 15 assists in a playoff game. Double-doubles from Bradley Beal (33 points and 10 rebounds) and Russell Westbrook (16 points and 14 assists) were not enough for the eighth-ranked Wizards.

The Suns trumped defending champions the Los Angeles Lakers 99-90 behind Booker (34 points) and Deandre Ayton (21 points and 16 rebounds). Back in the playoffs for the first time since 2009-10, the Suns used a 32-25 opening quarter to see off the seventh seeds in the series opener in the west, despite Chris Paul's shoulder injury. LeBron James had 18 points and 10 assists in a double-double display for the Lakers.

Randle struggles

All eyes were on All-Star Julius Randle after leading the New York Knicks back to the postseason for the first time since 2012-13. While he collected 12 rebounds, Randle was far from his usual best in the 107-105 defeat to the Atlanta Hawks. Randle finished six-for-23 shooting for 15 points in 36 minutes. The Knicks star made just two of his six three-pointers.

Anthony Davis was five-for-16 shooting in a team-high 39 minutes of action as the Lakers star recorded just 13 points against the Suns. He missed both of his attempts from beyond the arc. As a team, the Lakers were just 26.9 per cent from the three-point line after Kentavious Caldwell-Pope made just one of his seven shots.

Ice Trae!

Trae Young was the hero for the Hawks, who edged the Knicks in their series opener at Madison Square Garden. Young nailed the game-winner with 0.9 seconds remaining to silence the New York crowd in a thriller between the fourth and fifth seeds in the east. The Hawks guard finished with 32 points, 10 assists and seven rebounds. According to Stats Perform, Young is the first NBA player to make a game-winning field goal in the final five seconds in his playoff debut since Dwyane Wade in 2004.
