LOS ANGELES (AP) _ Tommy Maddox threw two touchdown passes, and Saladin McCullough ran for 164 yards on 21 carries as the Los Angeles Xtreme advanced to the XFL's first championship game by beating the Chicago Enforcers 33-16 Sunday.

The Xtreme will play the San Francisco Demons next Saturday at the Los Angeles Coliseum. The Demons advanced by beating the Orlando Rage 26-25 Saturday in the other semifinal.

Before a season-low announced crowd of 13,081 at the Coliseum on Sunday, Los Angeles' defense held its opponent without an offensive touchdown for the second straight game.

Chicago's only touchdown came when Kivuusama Mays blocked Noel Prefontaine's punt and Chike Egbuniwe returned it 2 yards. LeShon Johnson's 1-point conversion run gave the Enforcers a 10-9 lead with 1:45 left in the first half.

Los Angeles took the lead for good 11 seconds before the break on a 7-yard touchdown pass from Maddox to Damon Gibson, capping a 63-yard, eight-play drive. Maddox then passed to Darnell McDonald for a 2-point conversion, putting the Xtreme on top 17-10.

Chicago drove inside the Xtreme's 15-yard line four times in the game, but ended up settling for two field goals by Andy Crosland, with Kevin McDougal throwing interceptions on the final two possessions. Crosland also kicked a 40-yard field goal with 14:22 to play, cutting Chicago's deficit to 20-16.

The Enforcers were forced to punt after three plays on their next possession, and the Xtreme then put the game away when McCullough ran 44 yards for a touchdown with seven minutes remaining.

Chicago's John Avery, the XFL's leading rusher, was held to 59 yards on 14 carries. McDougal completed 15 of 31 passes for 228 yards, and was intercepted three times.

Maddox completed 18 of 24 passes for 171 yards, and Jose Cortez kicked field goals of 31 and 48 yards for the Xtreme.
