LOS ANGELES: The Memphis Grizzlies, fueled by a triple-double from teenager Cameron Boozer, topped the Portland Trail Blazers 124-103 in a battle of NBA unbeatens on Thursday, Portland guard Ja Morant's first game against his former team ending with an injury.

Boozer, taken third in June's NBA draft, scored 18 points with 12 rebounds and 12 assists for the Grizzlies.

The game in Portland was billed as Morant's reunion with the Grizzlies, the team that drafted him second overall in 2019. He earned Rookie of the Year honors in 2020 and emerged as a star in his seven-year tenure in Memphis.

He also had a pair of lengthy suspensions and, after multiple injuries limited him to 20 games last season, he was traded in June.
