Lonzo Ball and Dennis Smith Jr. have been two of the best rookies in Summer League, and they lined up head-to-head Sunday night in the Las Vegas semifinals.

They both had their moments. Ball was efficient with his shot — 5-of-7 shooting overall and 2-of-3 from three — and racked up 10 assists before leaving the game with calf tightness. It was nerve-racking when he limped off the court to the locker room.

Smith had 21 points on 7-of-13 shooting with six assists.

Check out their highlights above.

The Lakers won the game and advance to the Summer League championship game against the Trail Blazers on Monday.
