SPORTSTICKER NBA PLAYOFF PREVIEW (SAN ANTONIO-LA LAKERS) San Antonio at LA Lakers 5:30 pm EDT INGLEWOOD, California (Ticker) -- The San Antonio Spurs look to complete the first four-game playoff sweep in franchise history today when they face the Los Angeles Lakers in Game Four of the Western Conference semfinals. The Spurs have outgutted, outsmarted and outhustled the Lakers in taking a commanding 3-0 lead in this series, calling into question once again whether Los Angeles is just a big collection of misguided talent. The Lakers hope to avoid being swept out of the postseason for a second straight season as well as saving some face in front of the Great Western Forum faithful. The Lakers were outclassed in four games by Utah last season and have not given any indication that they can be the first NBA ever to overcome a 3-0 series deficit. With David Robinson hampered by foul trouble, Tim Duncan took control. Duncan scored 37 points and grabbed 14 rebounds to lift the Spurs to a 103-91 victory on Saturday. Jaren Jackson collected 22 points and Avery Johnson added eight. They combined to make a series of clutch shots down the stretch as San Antonio scored the game's final 13 points. The Spurs, who came into existence as an American Basketball Association team in 1973, have swept two best-of-five series but have never won the first four games of a seven-game set. "I want to finish the series (today)," Duncan said. "We've played three games where we've had to give it out to the end. We're finding ways to get it done because we keep playing defense." Shaquille O'Neal had 22 points and 15 rebounds but did not have a basket in the final nine-plus minutes for the Lakers. O'Neal, who came to the Lakers to be the centerpiece of a team that was supposed to return to the top of the league, is on the verge of being swept out of the playoffs for the fifth time in six years -- dating to his days in Orlando. "Personally, I'm not going to mail it in," O'Neal said. "We just have to come in and play with a lot of dignity, play with a lot of pride, just play. I don't want to mail it in." The Spurs have exhibited great depth in the series as their reserves have outscored the Los Angeles bench by a 59-22 count. Game Five, if necessary, will be at San Antonio on Tuesday.
