The victory over the Hornets also gave Boston its 50th win.

“A testament to the alignment of the organization and to the players,” Boston coach Joe Mazzulla said. “It’s a minor milestone. I wouldn’t say it’s a true definition of success, but I think it’s a definition of consistency.”

Notes: Atlanta coach Quin Snyder recorded his 500th career NBA coaching victory when Atlanta beat Sacramento 123-113 Saturday night … Before joining the Hawks, Snyder was Utah’s coach for eight seasons. He guided the Jazz to the postseason six times … “It was special,” said Snyder, 59. “When you’ve been in this league for a while you realize that coaches — they keep your record — but it’s really the players and the other people that allow for that to happen. I’ve been really lucky to be able to coach not just really good players, but some quality people. That makes it fun. It’s your extended family.” … Jock Landale, who was a late scratch because of right shoulder impingement when Boston beat Atlanta on Friday, had 19 points and 13 rebounds in the Hawks’ victory over Sacramento. It was Landale’s first double-double since he joined the Hawks on Feb. 5.
