As the gap at the top of the Eastern Conference playoff race got wider, the battle at the bottom stayed tight.

The Chicago Bulls defeated the Miami Heat 106-91 Tuesday night behind 39 points from Michael Jordan, increasing their lead to 21/2 games over Indiana and 3 1/2 over Miami.The New Jersey Nets dropped into a tie with Washington for the eighth spot by losing 79-78 at the buzzer to San Antonio, and the Orlando Magic fell a half-game behind the Nets and Wizards by losing 85-78 at New York.

Scottie Pippen added 19 points for the Bulls (46-16), who shot 54 percent in winning for the 12th time in 13 games.

Alonzo Mourning scored 21 points for Miami, whose road winning streak ended at 11 games.

Mourning elbowed Jordan in the head setting a screen early in the third quarter, but no foul was called. Mourning later elbowed Pippen while setting another screen, and Pippen got in Mourn-ing's face and threatened to slug the Miami center.

"(Mourning) can't get into my head and intimidate me," Jordan said. "He'll have to hit me harder than that."

"As you see, there's not much love," Jordan added. "I think a lot of it has to do with the way they approach the game. We have to be de-fi-ant, go out with our own objectives and do our jobs."
