LAS VEGAS (AP) Call it Midsummer Madness.
The NBA Summer League tournament is shaping up to be the most unpredictable bet in Las Vegas. The 30th and final seed advanced Thursday along with a No. 26 and a No. 27, after the Nos. 24, 25 and 29 seeds all won a day earlier.
The 30 teams in the Summer League all played three preliminary round games and then were seeded for the tournament. It didn't take long to determine those seedings were meaningless.
That was especially the case when the 30th-seeded Philadelphia 76ers won for the first time in Las Vegas by knocking off Deandre Ayton and the Phoenix Suns, who had won their first three games to earn the No. 3 seed.
The top-seeded Los Angeles Lakers were able to avoid the chaos. The defending Summer League champions defeated their Staples Center rivals, the 17th-seeded Clippers, in their opener.
Teams that lost Thursday play a consolation game Friday before the winning games return to action.

Isaiah Miles scored 20 points, making six 3-pointers, and Furkan Korkmaz added 18 for Philadelphia (1-3).
