LAS VEGAS - One prized rookie struggled with his shooting accuracy, and another promising young player gave everyone a scare after taking a tough fall.It was not exactly the summer league debut Lakers rookie point guard Lonzo Ball and second-year forward Brandon Ingram had in mind. In the Lakers' 96-93 loss to the Clippers on Friday at Thomas & Mack Center, Ball was held to five points, while shooting 2 for 15 from the field (1 for 11 from 3-point range).
