INDIANAPOLIS (AP) - Rasheed Wallace is perfect when guaranteeing playoff victories over the Indiana Pacers.

Just as they did a year ago, the Detroit Pistons delivered on Wallace's prediction - this time tying their second-round series with an 89-76 win in Game 4 on Sunday. Chauncey Billups scored 29 points, and Wallace had 17 points, 12 rebounds and a playoff career-high five blocks.

''It was answering the bell,'' Wallace said. ''We couldn't afford to go down 3-1 to this team.''

Last year, Wallace guaranteed a Game 2 win by the Pistons after they lost to Indiana in the opener of the Eastern Conference finals. Detroit went out and won that game - and the series - and beat the Los Angeles Lakers in the NBA Finals.

Mavericks 119, Suns 109

DALLAS (AP) - Josh Howard did exactly what Steve Nash used to for the Dallas Mavericks.

Howard scored 29 points and had 10 rebounds in an all-around performance Sunday night, helping lead the Mavericks to a 119-109 victory over Nash and the Phoenix Suns.

The Western Conference semifinal series is tied 2-2.

''He's our energizer. He was all over the place,'' Dirk Nowitzki said of Howard. ''He's our best defender and does a great job of keeping the ball alive for us.''

SuperSonics 101, Spurs 89

SEATTLE (AP) - Damien Wilkins has worked from this blueprint before. Just last month, he stepped in when Rashard Lewis was hurt and helped the Seattle SuperSonics win a few late-season games.

This time, it was a much bigger victory.

Wilkins came off the bench for 15 points, six rebounds and five steals, a solid complement to Ray Allen's 32 points as Seattle beat San Antonio 101-89 on Sunday, evening the best-of-seven series at 2.
