Coach Luke Walton says rookie Lonzo Ball remains the Los Angeles Lakers' starting point guard and that there is no talk of moving the No. 2 overall draft pick to the bench.

Struggling with his shot, Ball has not played in the fourth quarter of the Lakers' past two games -- a win against the Phoenix Suns and a loss to the Philadelphia 76ers. Walton instead rode with the strong play of sixth man Jordan Clarkson.

"He's our starting point guard," Walton said of Ball after practice Thursday. "So there's no discussion, no talks as of now of moving Lonzo to the bench. Nah. He's our starting point guard."

Walton said he was told Ball came to the practice facility late Wednesday night and worked on his shot after going 1-for-9 from the field, including 0-for-6 from 3-point range, in the 115-109 loss to the Sixers at Staples Center.

Ball finished with two points, two assists and five rebounds. He admitted afterward, for the first time this season, that he let his shot affect the other things he does to impact the game.

Walton noticed that the normally even-keeled, easygoing Ball wasn't as playful at the team facility Thursday as he normally is. "That could be a good thing that he's frustrated or mad a little bit," Walton said.

Ball is averaging 9.0 points, 6.9 assists, 6.6 rebounds and 1.3 steals but is shooting just 30.3 percent overall and 23 percent from behind the arc.
