DENVER (AP) _ Phil Bradley hit a three-run homer in the bottom of the ninth inning Sunday to lift the Seattle Mariners into an 8-8 exhibition baseball tie with the Chicago Cubs.

The game was called after nine innings because of a curfew agreed upon before the contest to allow both teams to make travel connections.

A crowd of 34,518 turned out in sunny, 55-degree weather and watched Chicago score a run in the first and two more in the second for a 3-0 edge.

Seattle tied the score with three runs in the bottom of the second and added two in the third to go up 5-3.

Chicago got a run in the fourth and went ahead 6-5 on Keith Moreland's two- run homer in the fifth. Chicago limited the Mariners to one hit from the fourth through the eighth innings. Meanwhile, the Cubs added runs in the sixth and ninth to boost their lead to 8-5.

In Seattle's half of the ninth, Spike Owen walked with one out and Harold Reynolds singled before Bradley blasted the ball over the 360-foot sign in left-center field to tie the game.

Sunday's turnout brought attendance for the two-game weekend series to 76,974. The games were promoted by Denver officials who hope to lure a major- league franchise to the Mile High City.
