Based upon the results of the two-day December trials, the George Mason High School Invitational track finals Saturday could produce the standards for the rest of the season. The indoor meet will start at 1 p.m.

Last year's meet produced eight records. Already, four have fallen in the trials heats.

Senior Chris Lockett of Woodbridge, last year's pole vault champion and co-record holder with Warren County's Irwin Grant at 14-feet, broke the record by six inches to lead 11 qualifiers into Saturday's final. His nearest competition, John Hirst of Lake Braddock, is no closer then a foot and a half.

Oakton's David Daigler improved on the meet's two-year mark in the high jump set by Richard Evans of H.D. Woodson by a half inch, clearing 6-8 1/2. He improved on his personal best by more than eight inches. Last year he tied for sixth at 6-0. Behind him at 6-4 are Dionnie Sharp of Falls Church and Kevin Borden of Hayfield.

Langley junior Erin Keogh produced perhaps the most dramatic record while running in the girls 3,200 meters. True to form, she shot to the front, eventually lapping all but two runners in her heat more than once, and finished with a 10:21.5. That time cut nearly 18 seconds off the two-year-old record established by Jefferson-Huegonot-Wythe's Demarch Robertson and gives Keogh a cushion of 23 seconds over Lake Braddock's Wendy Neely going into the final.

Central junior Kellie Roberts kept Maryland schools in the picture. She leads all qualifiers in both the 300- and 500-meter runs, with a record in the latter. Last year, Lake Braddock's Cathron Birge defeated Roberts in both events, running a record in the 500. But Birge is injured, leaving Roberts a practically unimpeded path the the finals.

Winning both events by large margins in her heats, Roberts ran the 500 in 1:13.9, erasing Birge's year-old 1:14.33. In the finals, the race will be for second place, as Fairfax's Robin Grim and Central's Karmen Roberts are the next fastest qualifiers at 1:20.0 and 1:20.1. Roberts also leads the 300 list at 40.5, almost two seconds ahead of Robinson's Ann McCool.

Lake Braddock's boys and girls produced enough top performances to be make their teams top contenders for the Virginia state indoor titles in late February. Sprinter Dana Boone holds the runner-up position in the 55-meter dash as well as the lead in the long jump. In the 55, Central's Jackie Johnson tops the list, although both runners enter the finals with identical 7.3 clockings. In the long jump, Boone leads defending champion Carmen Mann of Falls Church, 18-3 1/4 to 18- 1/2. Last year Mann set the record at 18-10 3/4.

In the pole vault, Hirst holds a margin of six inches over third-seeded Mason Shih of Langley.

The top four seeds in the boys 55-meter hurdles enter with best times of 7.5, but the favorites are Keith Crawford of Largo and Bart Bailey of Suitland. Last year, Bailey took fourth while Crawford settled for sixth at 7.8 and 7.9, respectively. Dione Wafford of Lake Braddock is the third seed.

Kim Marks and Mike Anthony head their respective 1,000-meter contingents. Marks, with a 3:02.6, leads last year's champion, Ashley Riggs of Severna Park, by 1.3 seconds. Anthony, the defending champion at 2:32.97, clocked a 2:32.8 in his trials heat to lead Chantilly's Dave Patterson's 2:33.3.

Mount Vernon's Jean Burris and Stuart's Jeremy Worrell return to defend their crowns in the girls shot put and triple jump events.

Last year Burris put the shot 40-5 1/2 to win by more than four feet. This year she enters the finals with even a larger lead, hitting 42-11 1/2 for the top seed.

Worrell won last year's contest by over a foot at 47-4 1/2. He's well ahead of that this year, having cleared 48-10 1/2 to lead the triple jumpers into the finals. His closest competitor, Matt Darby of Green Run, cleared 47-6.
