-- MIAMI (Ticker) -- A clash of titans highlights the NBA schedule Sunday as Tim Duncan and the San Antonio Spurs visit Shaquille O'Neal and the Miami Heat in a matchup of conference leaders. The Spurs won the first meeting on November 12 at home. They have won 10 of their last 12 games overall and are 4-1 on a current seven-game road trip. Tony Parker has been the star of San Antonio's trip, leading his team in scoring in the last four games and keying a comeback victory at New Jersey on Friday. Parker scored 17 of his 27 points in the fourth quarter Friday as the Spurs rallied for a 101-91 win. He is averaging 21.6 points, 7.6 assists and 6.8 rebounds on the road trip. Friday's win, coupled with a loss by the Phoenix Suns, gives San Antonio a one-game lead in the Western Conference standings. Although their last three wins have come against some of the league's lesser teams, the Heat have won five in a row and own a 6 1/2-game cushion in the Eastern Conference. O'Neal scored 32 points and grabbed 12 rebounds in a 97-87 win over the Charlotte Bobcats on Friday. The Heat turned the ball over 17 times and made just 10-of-27 (37 percent) free throws but used a big third quarter to grab the win. Miami also has won five straight at home but is just 11-10 against Western Conference opponents. Manu Ginobili scored 29 points and Parker added 18 in the Spurs' 93-84 win over the Heat in November. It marked San Antonio's sixth straight win in the series.
