Stephon Castle delivered a career performance, scoring 42 points to record just the second 40-point triple-double in NBA history by a player under 22. The San Antonio Spurs guard connected on 78.9% of his shots while adding 12 rebounds and 12 assists in a 138-125 victory over Dallas.

Castle's historic night came against the Mavericks for the second time in three days, with coach Mitch Johnson praising his balance and attack mode. The victory extended San Antonio's win streak to four games and gave the franchise 36 victories before the All-Star break, matching their total from the 2016-17 season.

Fact: Castle became the youngest NBA player (21 years, 98 days) to record a 40-point triple-double.

Castle joined an exclusive club as just the ninth player in Spurs history with multiple triple-doubles. His performance included making his first 10 shots and lasted only 31:51, the second-quickest 40-point triple-double since minutes were first tracked in 1970-71.
