Tim Duncan scored 25 points and Tony Parker added 24 to help the San Antonio Spurs rally for a 99-91 victory over the Houston Rockets on Wednesday night.

The Spurs (14-9), who trailed by as many as 18 points in the third quarter, have won two straight and improved to 11-1 at home. Gary Neal had 15 for San Antonio, which split the four-game season series with the Rockets (12-10), who have lost two straight.

Kevin Martin scored 29 points to lead Houston but went 1 for 6 in the fourth quarter. Kyle Lowry and Courtney Lee each added 15, and Patrick Patterson had 10.

The Rockets led by 18 points in the third quarter and looked poised to put the game away before Duncan led the Spurs on an 11-2 run. When he wasn't barking directions to his younger teammates, Duncan was burying running hooks in the lane. Duncan scored 16 points in the quarter, after which the Spurs trailed only 71-67.

The Spurs took their first lead since the first quarter on Danny Green's 3-pointer with 7 minutes left in the game — a shot that brought his former coach Roy Williams, in attendance to support Green, to his feet. Both teams traded baskets before the Spurs took the lead for good on Neal's runner with 2 minutes left. San Antonio closed the game on a 6-0 run.

Houston led 52-39 at halftime behind 21 points from Martin, who returned this week from a two-game absence because of a twisted right ankle. He's picked up right where he left off before the injury, scoring 29 against Minnesota on Monday and hitting 6 of 11 3-pointers against the Spurs.

With his characteristic quick release, Martin hit 5 of 7 3-pointers in the first half, often in the face of late-arriving Spurs defenders.

Martin wasted no time reaching double figures for the 19th time this season — the only time he didn't was in the season opener. His 3 with 7:18 left in the first quarter gave him 11 points and capped a 13-2 Rockets run.

When Lee wasn't burying jumpers, backup guard Courtney Lee picked up the offense. He had 11 points on 5-of-6 shooting in the half.

The Rockets held the Spurs to 14-of-39 shooting in the half. Parker led the Spurs with 13 points and Duncan had nine.

Notes: Williams coached Green at North Carolina from 2005-2009. . The Spurs have two more home games before going on the road for nine straight games. The Rockets will play six of their next seven games on the road. . The Spurs have won 32 of their last 38 home games against the Rockets.
