The Oklahoma City Thunder, fueled by 38 points from Shai Gilgeous-Alexander, held off the Memphis Grizzlies 117-115 on Saturday to complete a 4-0 sweep in their NBA Western Conference playoff series and become the first team to reach the second round.
The Cleveland Cavaliers were on the brink of advancing, taking a 3-0 stranglehold on their Eastern Conference series with a 124-87 blowout of the Miami Heat.
And the Denver Nuggets leveled their Western Conference series with a stunning 101-99 victory over the Los Angeles Clippers sealed by Aaron Gordon's put-back dunk at the final buzzer.
Jalen Williams added 23 points for the Thunder, who were pushed to the wire in Memphis despite the absence of Grizzlies star Ja Morant, who was ruled out with a hip contusion suffered in game three.
