The Oklahoma City Thunder completed a dominant 4-0 sweep of the Phoenix Suns in the Western Conference first round of the 2026 NBA Playoffs with a 131-122 victory in Game 4 late Monday night. As the No. 1 seed and reigning champions, the Thunder became the first team to advance to the conference semifinals.

Shai Gilgeous-Alexander led Oklahoma City with 31 points, eight assists, and two steals in the finale, capping a stellar series where he averaged over 33 points per game. Chet Holmgren also contributed significantly throughout the matchup, bolstering the Thunder's top-ranked playoff offense and defense.

The series began with a resounding 119-84 Thunder win in Game 1 on April 19, where Gilgeous-Alexander scored 25 points. Oklahoma City followed with a 120-107 triumph in Game 2 on April 22, as SGA posted 37 points and nine assists. Game 3 on April 25 saw the Thunder prevail 121-109 in Phoenix, highlighted by Gilgeous-Alexander's playoff career-high 42 points.

Oklahoma City's young core extended its first-round playoff winning streak to 10 games dating back to previous postseasons. The Thunder outscored the Suns by an average of 17 points per game, showcasing superior efficiency with a 54.5 effective field-goal percentage compared to Phoenix's 48.8.

The Suns, led by efforts from Devin Booker and Dillon Brooks, struggled to contain Oklahoma City's versatile attack. Phoenix's offense rated at just 105.2 points per 100 possessions in the series.

With the sweep, the Thunder now await the winner of the No. 4 Los Angeles Lakers-No. 5 Houston Rockets series, where the Lakers hold a 3-1 lead heading into Game 5 on Tuesday night. The Western Conference semifinals are expected to begin later this week.

Oklahoma City's title defense continues amid high expectations for the squad built around Gilgeous-Alexander, Holmgren, and supporting pieces like Jalen Williams.
