Hensley won the 100-meter hurdles (15.1 seconds), 300 hurdles (46.4) and high jump (5 feet) and teamed with the rest of the Big Four to win the 1,600 relay (4:12.0) - one week after they set an all-time Washington County record in the 1,600 relay (4:04.53) at the Penn Relays.
"We're getting into the meets that count, getting down to it," said Hensley, who helped lead Boonsboro to last year's Maryland Class 1A state team title. "So you have to let it all out."
Harnett won the 400 (1:00.3) - while Robertson and Walla took second and third - and came back to nip Williamsport's Laura Forsythe for the victory in the 800 in 2:26.5 - the same time given to Forsythe.
"I have really bad allergies right now and was coughing really badly after the 400," Harnett said. "But the coach said he needed me to do (the 800) for the points.
"I don't have a choice," she said, jokingly.
Robertson, the runner-up in the 200, and Walla, the runner-up in the 300 hurdles, also teamed with the Reese twins, Katie and Kelli, to win the 400 relay (53.6).
Brunswick, which finished third, had a pair of double winners. Racheal McCallum won the 100 (12.2) and 200 (25.8), and Becca Tucker took the long jump (15-11 3/4) and triple jump (34-8 3/4).
Clear Spring's Ashley Lockard won the 1,600 (5:29.4) and 3,200 (12:22.9).
n The only meets remaining before states are the county and regional championships. So the Smithsburg boys team has two more chances to "practice."
"All the meets up to states are practice," said Chad Brown, who won the 100 (11.0), 200 (22.7) and anchored the winning 400 relay (45.3) to help lead Smithsburg to a winning total of 143 points.
"This is a tuneup," said Leopard Derek Martin, who got victories in the 110 hurdles (15.5), 300 hurdles (41.3) and 400 relay. "As a team, we want states. It's been since 1978 that there's been a boys state championship in track, and we want to bring it back home."
First, they'll need to work some more on their relay handoffs. After Brown brought the baton home in first place in the 800 relay, the team was disqualified for having made an illegal exchange.
"We definitely have to get it together," Brown said. "We'll work it out."
Smithsburg also got a victory from Lucas Howard in the triple jump (40-1).
For North Hagerstown, which took second with 99 points, Hemu Arumugam won the 1,600 (4:35.1) and 3,200 (10:31.4).
Williamsport's Seth Shrader got wins in the 400 (51.9) and 1,600 relay (3:34.5).
