Jayson Tatum scored a career-high 60 points as the Boston Celtics stormed back from a 32-point first half deficit for a 143-140 overtime win over the San Antonio Spurs at the Boston Garden.
Tatum's point total equalled Boston icon Larry Bird for the most points scored in a game in Celtic's history and he is the second youngest player ever in the NBA behind Devin Booker to post a 60-point game.
The 23-year-old Tatum made four free throws in the final 12 seconds of overtime for the Celtics who roared back from a 29-point halftime deficit to level the score halfway through the fourth quarter on Friday night.
Tatum hit a three pointer with 38 seconds left in the fourth to give the Celtics their first lead 127-126 since early in the first quarter.
Tatum hit a free throw with 18 seconds to play to give the Celtics' a two point lead, but San Antonio's DeMar DeRozan tied the game with 10 seconds to go to set the stage for a thrilling overtime.
Jaylen Brown added 17 points for the Celtics and Aaron Nesmith had 16 points in the win.
DeRozan scored 30 points and dished out a career-high 14 assists for the Spurs who dropped to 31-31 on the season.
In New York, Damian Lillard finished with 32 points and nine assists to lead the Portland Trail Blazers to a convincing 128-109 victory over the Brooklyn Nets.
Jusuf Nurkic delivered 23 points and 11 rebounds as Portland improved to 3-0 on a six-game road trip after losing five straight.
Lillard drained eight three pointers for the Trail Blazers, who improved to 35-28 and are putting together a string of wins as they gear up for the playoffs.
"We have been terrible for awhile, but we are putting it together at the right time of the year," Lillard said. "The way we have won games is more important than just getting the wins.
"We have defended and moved the ball. It is the way we want to play in the postseason."
