BYU junior Maxine Scringer shaved four-hundredths of a second off her school record in the 400-meter dash at the Northern Arizona open invitational Saturday with a clocking of 55.27 to finish second in the event.

Freshmen newcomers Christy Opara of Nigeria and Evelyn Cobinnah of Ghana also picked up second places for the Cougars. Opara ran the 55-meter dash in a time of 6.95, and Cobinnah, the top female long jumper in Ghana, sailed 19 feet 71/2 inches in the long jump.Opara placed third in the 200-meter dash in 24.55, missing the NCAA qualifying time of 24.25.

BYU's veteran hurdler Susan Christensen improved her season's-best time in the 55m hurdles with her fifth-place finish of 8.10, but failed to meet the NCAA standard of 7.90.

Also placing fifth for BYU were Kelly Delph in the long jump with 18 feet 83/4 inches, and Sheri Jo Coleman in the triple jump with a 35 feet 103/4 inch mark.

Because the meet was an open event attracting several standout non-collegiate performers, no team scores were kept.
