Cooper Flagg made his NBA Summer League debut Thursday night and although he and the Dallas Mavericks earned the win, the No. 1 NBA Draft pick called it “one of the worst game of my life.”

We've got a big summer weekend ahead, highlighted by the MLB Draft and the run-up to next week's All-Star Game, the completion of Wimbledon -- you can follow this morning's men's semifinals here-- and one of the year's most anticipated boxing matches of the year happens tonight.

LAS VEGAS (AP) — Cooper Flagg strolled into UNLV’s Thomas and Mack Center at 4:17 p.m. on Thursday, wearing Dallas Mavericks gear, bright white New Balance shoes, and an emotionless look on his face as he passed through security.
