The longest active winning streak of an active NBA player over another is 15-0: Held by Kawhi Leonard over Zach Lavine. The Clippers host the Kings for the first time this season on Tuesday.
This is a streak that goes back since 2014 and I don’t think any other player holds a longer winning streak over another current player than Kawhi has over Lavine.
Note: Lavine has been injured but is set to be re-evaluated around the time the game happens so idk, he might play.
Player Injury: Out (Ankle) - LaVine will be re-evaluated in one week, James Ham of ESPN 1320 Sacramento reports. (Updated Dec.23, 2025)
