Wayne Rainey takes pole, then it's Kevin Schwantz and Eddie Lawson.

Schwantz cruises into the pits with a mechanical, and Lawson closes the gap to Rainey and moves into the lead.

Sarron is in third a couple of bike lengths behind, and Wayne Gardner passes Magee for fourth spot.

With two laps to go, Rainey is right behind Lawson and highsides on the exit of a right-hander.

Though it's Rainey's only real mistake all year, Lawson's consistency and improvement brings him the win and a lead in the standings by 13.5 points.
