Watch Oklahoma City Thunder vs Boston Celtics — NBA Finals Game 4 Free.

What's at Stake

The Larry O'Brien Trophy is within reach as the NBA Finals reach a fever pitch at the Paycom Center in Oklahoma City. With the series currently at 2-1, this Game 4 serves as the ultimate pivot point: the Celtics look to secure a commanding 3-1 stranglehold, while the Thunder fight to equalize the series and ensure a return to Boston with momentum on their side.

Head-to-Head

These two cross-conference powerhouses have split their regular-season meetings over the past two years, but the postseason has intensified the rivalry. Boston has relied on their veteran championship experience to grind out narrow victories, while Oklahoma City has utilized their superior transition speed to dominate at home. Recent matchups have been decided by fewer than five points, highlighting the razor-thin margin between the Celtics' defensive discipline and the Thunder's explosive youth.

Key Players to Watch

• Shai Gilgeous-Alexander — The Thunder’s primary engine who must navigate Boston's elite perimeter defenders to create scoring opportunities.
• Jayson Tatum — The Celtics’ cornerstone who remains the focal point of the offense and a critical versatile defender in small-ball lineups.
• Chet Holmgren — A vital rim protector whose ability to stretch the floor will be tested against Boston's physical frontcourt rotation.

Prediction

Expect a defensive slugfest as both teams adjust to the high-pressure environment of a potential close-out swing. Oklahoma City’s home-court energy is likely to provide the edge needed to even the series, narrowly defeating Boston 108-104. The Thunder’s depth and perimeter shooting should prove just enough to overcome the Celtics' tactical execution in the closing minutes.
