MEMPHIS, Tennessee — Rookie Cameron Boozer had 27 points and nine rebounds, and Isaiah Stewart added 24 points as the Memphis Grizzlies remained the only unbeaten team in the NBA with a 136-105 victory over the Sacramento Kings on Saturday (Sunday in Manila). The Grizzlies’ 6-0 record matches the 2014-15 season for the best start in franchise history. After the Houston Rockets’ 116-111 loss at Dallas on Friday night, Memphis was the last unbeaten team in the league. The Grizzlies dominated the Kings in the second half to coast home, with the lead reaching 34 in the second half. GG Jackson finished with 21 points, connecting on all five of his 3-pointers as Memphis built its lead in the first half. Cam Spencer, starting at point guard as Ty Jerome and Scotty Pippen Jr. sat out with back issues, had 10 points and 13 assists. Meanwhile, the Kings, led by 38 points from Darus Acuff Jr., continue to struggle in the season’s early stages, dropping to 0-6. Acuff, the rookie from Arkansas, scored 34 points against New Orleans in a loss Thursday; De’Andre Hunter finished with 19 points. Domantas Sabonis and Zach LaVine scored 11 points each, Sabonis adding 14 rebounds and eight assists. Memphis led by 21 points in the first half behind Jackson’s 3-point shooting, but Acuff was able to keep the Kings into the game with 21 first-half points. The Grizzlies led a 66-55 lead at intermission as Jackson connected on all five of his 3-point attempts. The double-digit margin ballooned to 30 in the third quarter as Stewart and Boozer, the third pick in last summer’s draft, fueled the Memphis offense. The Grizzlies outscored Sacramento 42-25 in the third. Meanwhile, Jabari Smith Jr. had 30 points and nine rebounds, Marcus Smart added 24 points and the Houston Rockets beat the Oklahoma City Thunder 119-98. Smith shot 10 of 18 from the field, including 6 of 12 on 3-pointers. Smart was 7 of 10 on 3s as the Rockets shot 46 percent as a team and were 18 of 41 from behind the arc. Alperen Sengun, who returned to the lineup after missing the last two games with lower back soreness, finished with 16 points, nine rebounds and 10 assists, and Kevin Durant scored 14 points. Shai Gilgeous-Alexander had 26 points on 10-of-20 shooting, and Kenrich Williams and Bennett Stirtz scored 11 apiece for Oklahoma City, which lost its second straight after beginning the season 4-0.
