Old Mill senior Alexis Franklin captured three sprint victories Saturday at the SMAC Invitational—the 55-meter hurdles, 300 and 500—and two of them came in record-breaking fashion.

Franklin, the defending Maryland 4A hurdles champ, easily ran away from Howard’s Christine London and the rest of the eight-runner field inside Prince George’s Sports & Learning Complex in Landover before crossing in 8.14 seconds. The 8.08 she ran in the semifinal is the second-fastest time of her four-year career and is the meet record. London was runner-up in 8.36.

The All-Met outdoor track Athlete of the Year last spring followed that up a couple of hours later with a victory in the 500, edging Western Tech’s Sharon Dorsey at the line in a personal-best 1:17.42.

Franklin’s final individual event was the 300. Again, she was just too strong for the field, using a fast start and a burst at the end to finish in a meet-record 40.08. That time is fastest of her career and tops in Maryland so far this season.

Despite Franklin’s efforts, Old Mill finished seventh in the team standings. The top three squads were Elizabeth Seton, Hereford and Western Tech.

Thomas Stone won the boys’ competition ahead of Quince Orchard and Oakton.

Athletes brought several of the meet’s more modest records to a higher level of respectability. Oakton’s Michael McNamee won the boys’ 1,000 by nearly six seconds. His time of 2:33.96 shattered the previous record of 2:39.30 set in 2009.

In the first race of the day, McNamee anchored the Cougars’ 4x800 relay team that won in 8:05.10. The previous meet record of 8:10.89 was set in 2007 by West Springfield.

Thomas Stone was powered by Rakeem Jones. The senior owned the second-fastest qualifying times in the first two rounds of the 55 hurdles, but pulled out the victory in the final in 7.82. Jones had a little trouble in the semifinals of the flat 55, grabbing the eighth and final qualifying spot, but powered to the finish in the final to place third. Friendly’s Dajahn Lowery was the winner in 6.55.

Wise’s Beysean Hamilton was a double winner, breezing to victory in the 300 in 35.36 after taking the 500 just as easily in 1:07.52.

Chelsie Stevens helped key Elizabeth Seton’s team victory. She was the 55 meters champion in 7.18, but she didn’t go unchallenged. Magruder’s Bethany White was a close runner-up in 7.19.

Clarksburg’s Bailee Freeman performed well in the field. The senior was the only high jump participant to break five feet, winning with easily with 5-4. She also was fourth in the long jump and fifth in the triple jump.
