Palo Alto's inability to shut down three-point shooters cost the Vikings again in a 59-56 nonleague boys' basketball loss to visiting Burlingame on Saturday night. Paly (17-4), which gave up 32 points and seven 3-pointers to Gokul Natesan in a loss to Cupertino on Friday, gave up nine treys to the Panthers (15-7). Paly has given up 23 three-pointers in its past three games.
