The technique worked as Bishop Feehan defended its title with a strong 75-point performance at Saturday’s championships at Pembroke High School.

“[They] picked Hingham to basically run away with this because they had better sprinters and we didn’t have any field events,’’ Powell said. “Our girls rose to the occasion.

“The girls worked hard this spring, our sprints really stepped up, our field events did what they needed to do, and it paid off.’’

Hingham was second with 66 points and Foxboro (46), Burlington (44), and Hopkinton (41) rounded out the top five.

Bishop Feehan was 8 points ahead of Hingham with just the relays left to run. But the Shamrocks put on a fine performance.

They won the first relay, the 4 x 800, in 9 minutes 35.53 seconds. The time set a meet record, breaking the mark of 9:38.09 set by Bishop Feehan in 2010.

“I was psyched about the [meet record],’’ said Powell. “I thought they could do it.’’

The Shamrocks also won the 2-mile run when Abby McNulty finished in 11:09.49. While only winning those two events, Bishop Feehan was strong across the board, finishing in the top four in six additional events.

Other winners were Hopkinton’s Jessica Scott (100, 12.45); Foxboro’s Andrea Marcotte, (200, 25.87) and Liz Holmes (mile, 5:03); Hingham’s Sierra Irvin (400, 59.50) and Meghan Patrolia (100 hurdles, 14.79); Medfield’s Taylor Worthy (800, 2:18.56); Canton’s Victoria Tondre (long jump, 17 feet 8 inches), Burlington’s Casey Landry (triple jump, 35-0); Wakefield’s Elizabeth Bray (shot put, 41-5); O’Bryant’s Adrienne Thornton (discus, 132-9); and Marblehead’s Kelly Roland (javelin, 110-7).

In the boys’ meet, Hingham romped with a 106-point performance. Host Pembroke took second with 84 points and Bishop Feehan (61), Triton (49 1/3), and Burlington (32) rounded out the top five.

Hingham started the day off strong, with Mike McConville finishing second in the 2-mile (9:31.72) to Pembroke’s Wesley Gallagher (9:27.02). McConville then came back to run the mile, finishing fifth (4:31.32). Burlington’s David Taranto won the mile in 4:24.00.

“I think [Mike] is the inspiration for this team now,’’ Hingham coach Fred Jewett said.

“He gets to run early and he runs so hard and he trains so hard. He stepped up and ran so well in the 2-mile and then came back in the mile, and they saw what he did. I think it makes them so excited.’’

Hingham also took first in the high jump (Chris McDowell, 6-4), shot put (Brian Sullivan, 51-1), discus (Sullivan, 155-9), 200 (Andrew Bolze, 22.02), 4 x 100 (44.41), and the 4 x 400 (3:26.12).

Pembroke took the 4 x 800 relay (8:06.01), setting a meet record, breaking the mark of 8:07.7 set by Oliver Ames in 1998.

Pembroke’s Kris Horn won three events (100, 10.82; triple jump, 46-0; long jump, 23-11).

Other boys’ winners: Pembroke’s Joe Vercollone (800, 1:56.57); Bishop Feehan’s Matt Taylor (400, 50.15) and Billy Ward (400 hurdles, 55.46); Triton’s Ryan Clay (javelin, 176-1); and Apponequet’s Dylan DeMoranville (110 hurdles, 14.84).
