ON THE SIDELINES : Martin Leads Mobil Grand Prix

Hurdler LaVonna Martin, who has beaten Jackie Joyner-Kersee three straight times, has the undisputed lead in the women’s overall Mobil Grand Prix indoor track and field circuit.

Martin, tied with distance runner Diana Richburg for the top spot last week, took sole possession of first place by beating co-world record-holder Joyner-Kersee in the 55-meter high hurdles in the Meadowlands Invitational Friday night at East Rutherford, N.J.

After eight Grand Prix meets, Martin has 49 points. Richburg, fifth-place finisher in the mile at the Meadowlands Invitational, is second with 42 points.

High jumper Hollis Conway, who finished in a tie for second in the Meadowlands Invitational, retained first place in the men’s overall Grand Prix with 47 points. Doug Padilla, winner of the 3,000 meters Friday night, is the runner-up with 40 points.

There will be two more Grand Prix meets this week--the Times-Eagle Indoor Games at Los Angeles Friday night and the Cleveland Knights of Columbus event Saturday night.
