SAN FRANCISCO — Ja Morant, the Memphis Grizzlies' sensational rookie, made his return Monday night against the Golden State Warriors after missing four games with back spasms stemming from a collision two weeks ago with a cameraman along the baseline. Morant, the Rookie of the Year favorite, led his team to a 110-102 victory and finished with a game-high 26 points and seven assists. The explosive guard even had a few thunderous dunks and a two-handed rim-rattler in traffic that put the Grizzlies up eight with a minute left to seal the win.
