DALLAS, Texas — Dallas Mavericks rookie Jalen Brunson poured in a career-high (game-high) 34 points (12-16 FGs, 3-6 3FGs, 7-7 FTs), including 12 in the second quarter and 10 in the third, to go along with five rebounds, four assists and one steal in 37 minutes. But it wasn’t enough as the San Antonio Spurs beat the Mavs 112-105 Tuesday night.
