PHOENIX (AP) — Deandre Ayton scored a season-high 28 points and had 12 rebounds, Devin Booker added 21 points and the Phoenix Suns stayed on top of the Western Conference with a 108-102 victory over the Detroit Pistons on Friday night. The Suns have won three straight games and four of five. The Suns led 84-79 going into the fourth quarter. They pushed it to 94-85 by midway through the fourth, but the feisty Pistons scored the next eight points.

Cameron Payne added 16 points and 10 assists. Bojan Bogdanovic had 19 points for Detroit.
