SAN ANTONIO (AP) _ Reserve Jaren Jackson made seven 3-pointers and led a second-quarter spurt that sent the San Antonio Spurs over the Dallas Mavericks 106-90.

Jackson finished with 23 points as the Spurs won their 18th straight regular-season game, a span that began last season.

The Spurs won despite making a franchise-low two of five foul shots.

San Antonio led 35-32 with 4:09 left in the first half before Jackson scored eight straight points, including a pair of 3-pointers. The Spurs led 48-36 at the break and Dallas never got within double digits in the second half.

Jackson, averaging five points a game, took 16 shots from 3-point range and hit a career-high seven.

The Spurs, concerned about perimeter defense following recent losses to Utah and Milwaukee, held the Mavericks to only 3-for-8 from the 3-point line and 37 of 92 (40.2 percent) overall.

Tim Duncan had 19 rebounds for the Spurs. Michael Finley scored 19 points for Dallas.
