SAN ANTONIO, Oct. 21 (Ticker) -- Brent Barry may be getting up there in years but showed he can still play a little bit.

Barry scored 13 of his 15 points in the second quarter to lift the San Antonio Spurs to a 103-93 preseason victory over the Miami Heat.

Tony Parker scored 17 points and Michael Finley added 15 for the Spurs, who shot 48 percent (35-of-73) from the field and held a 47-39 rebounding advantage.

Barry, 34, has seen his role reduced with the Spurs and nearly was dealt at the trading deadline last season. But the former Slam Dunk champion made three 3-pointers in the second period, when the Spurs built a four-point lead to 55-39 at halftime.

Bruce Bowen scored 12 points and Jackie Butler added 11 for San Antonio, which won despite just three points on 1-of-3 shooting by superstar Tim Duncan.

Shaquille O'Neal scored 24 points and fellow superstar Dwyane Wade added 23 for the Heat, who shot under 37 percent (30-of-82), including 2-of-19 from the arc.

Starters Udonis Haslem and Jason Williams did not play for Miami, which has dropped four of five preseason games.
