BURLINGTON — The Milton girls’ team used a late push by its short-distance runners to take first place at the Division 3 outdoor championships Saturday.

It was a two-way battle between the Wildcats, who finished with 111 points, and Tewksbury, which racked up 103.

“Coming in, we had a really strong feeling it was going to be us and Tewksbury, and I felt we were both going to get over 100 points,’’ Milton coach Tom Shaw said. “We knew it was going to take over 100 to win and it was going to be a win by 5 points, which sounds hard to think about. But everyone girl did her part. ’’

The Redmen grabbed an early lead, amassing 33 points over the first three events to build a 21-point cushion. But Milton put together a 14-point effort in the 100-meter dash — led by junior Abigail Jean-Baptiste’s first-place finish in 12.53 — to catapult the Wildcats into first place with just the 4?x?800, 4?x?100, and 4?x?400 remaining.

Milton junior Colette O’Leary ran 2:12.51 in the 800 meters to capture first and set a meet record in that event.

Not to be outdone, O’Leary’s freshman sister, Elise, ran a 56.86 in the 400 meters and a 64.58 in the 400-meter hurdles, both good for gold.

Sophomore Rachel Sessa submitted a strong performance for Tewksbury, which won the outdoor relays at Burlington earlier this month. She won the mile event at 5:04.51 and brought the Redmen from eighth to second on the last leg of the 4?x?800.

Plymouth North (56), Bishop Feehan (43), and Pentucket and Pembroke (41) rounded out the girls’ top five.

On the boys’ side, Burlington won with 78 points to sweep the Division 3 outdoor meets this season.

“At the start of the year we said we thought we could be league champions, relay champions, and state champions,’’ Burlington coach Matt Carr said. “And we filled all three.’’

After pentathlon winner Dylan Bonifilio, a junior, set a meet record with 2,897 points on Thursday, Burlington never looked back. The Red Devils made their biggest gains in the field events.

Junior Fernando Lamin won the triple jump at 45 feet ½ inch and strung another gold medal around his neck by posting a 6-6 in the high jump.

“There wasn’t a single area where we were let down today,’’ Carr said. “I’m psyched. Couldn’t ask for more.’’

Marblehead senior Andrew Ernst’s 1:53.03 in the 800 broke a 19-year-old meet record by more than two seconds. In the mile, Ernst coasted in at 4:23.84, nearly eight seconds before the next runner crossed the finish line.

Bishop Feehan (64), Pentucket (46), Milton (45), and Pembroke (43) were the next top finishers in the boys’ competition.
