The Oklahoma City Thunder arrive at Mortgage Matchup Center tonight with a chance to complete a NBA Playoffs first-round sweep of the Phoenix Suns at 9:30 p.m. ET on NBCSN and Peacock.
The Thunder lead the series 3-0 after a 121-109 victory in Game 3. This is obviously a must-win for the Suns or else their season is over.

- Total: O 215 (-110) | U 215 (-110)
- Moneyline: Thunder -560 | Suns +410
