Sandro Mamukelashvili scored 34 points on 13-for-14 shooting in 19 minutes to become the first player in NBA history to score 34 points while playing less than 20 minutes as the San Antonio Spurs upended the New York Knicks 120-105 .

Instead, the Knicks suffered one of their most embarrassing losses of the season, trailing by as many as 28, then making a furious third-quarter run to cut the deficit to as little as eight before the Spurs (29-39) ran away with a 120-105 victory at the Frost Bank Center on Wednesday.
