ATLANTA — Kyrie Irving scored 35, Jayson Tatum added 21 and the Celtics held off the Hawks 110-107 Monday night for their ninth straight victory. Irving's 3 from the right wing put the Celtics up 104-103 — the game's 25th lead change — with 1:37 left, and Boston led the rest of the way. Dennis Schroder had 23 points for the rebuilding Hawks, who dropped to 2-9 a night after a surprising two-point win at Cleveland. Boston improved to 9-2, best in the NBA, and has its longest winning streak in seven years. Al Horford had 15 points, 10 rebounds and nine assists in his best game against the Hawks. The former Gator spent his first nine seasons in Atlanta before leaving as a free agent before last season and had totals of 20 points and 17 rebounds in three games against the Hawks. Irving had his first 30-point game as a Celtic on a night packed with highlights. He dribbled between his legs and behind his back before hitting a floater off the glass from the left baseline to put Boston up 46-44. He had two impressive assists late in the third with long, one-handed passes that led to 3s by Marcus Smart and Tatum, the latter giving Boston a 72-71 lead. And Irving fed Horford for a dunk that was part of a 13-0 run that put the Celtics up by six. AROUND THE LEAGUE: Spurs guard Derrick White has a fractured right wrist and is out indefinitely.
