And just like that, Holliston great Carmen Luisi is back pulverizing quality competition as she has done so many times the last four years.

Luisi’s win in the 1000 at Saturday’s second day of the MSTCA Northeast Invitational will go down as one of her finest moments on the track.

The Syracuse University-bound speedster spread the field into a single file with her aggressive pace and she held off a late-charging Mia Paolino from Burnt Hills (NY) with a five-second personal best and new school record of 2 minutes, 53.25 seconds. Paolino was right there at 2:53.28. Halley Kavanagh of Oyster Bay (NH) clinched the bronze medal in 2:55.33. Luisi’s teammate Maggie Kuchman was fourth in 2:58.80.

Luisi has been gaining strength since illness kept her from possibly winning a third Div. 2 All-State cross country title.

“I’m feeling good,” she said. “I’ve been getting in a lot of speedwork. I wanted to run fast today. The people in my race were good and I wanted to take it out and keep an honest pace.”

Sarah Dumas of Franklin made the decision to concentrate solely on the 55 hurdles and it proved to be the right one for the Panther standout. And despite racing against a deep, talent field, the finish wasn’t close.

Dumas was out fast and never trailed in the final as she surged across the finish line in a personal best of 8.41 to lower her own school record. “I’m really happy with my starts today,” she said. “I wanted to focus on this and it paid off.”

Lowell’s terrific hurdler, Khai Yin, didn’t let a small cold stop him from dominating the 55 hurdles. Yin had a slight slip on his second step, but regrouped and bolted across the finish line in a personal best of 7.58. The time is also the Mass No. 1 mark this winter.

“On my second step I slipped a little bit,” said Yin. “I recovered pretty quickly though. My season is going well so far. I want to run in the low 7.5s.”

Dylan Brown of Wachusett was willing to wait before making his final move in the 1000, which he did on the final lap on the way to a 2:33.53 win to edge out Christopher Kardos of Algonquin (2:35.90) and Minnechaug’s Aren Brubach (2:36.26).

“I wasn’t sure how the race was going to play out,” said Brown. “I knew I was going to have to work hard to win. I usually rely on my kick.”

Revere’s Joao Victor Cunham of Revere locked a 1:24.28 for a win in the 600 and Sican Hinton of Weston ran 1:37.17 for the win on the girls’ side. In the high jump, Harvey Lys of Andover won with a 6-4 leap and Diman’s Grace Flattery sailed over 5-2 to capture the gold medal. Xaverian’s Mitchell Kisgen ran 35.49 to take the 300 and the great Abby Desmarais of Framingham ran a stellar 40.76 for a 300 win.

Brookline’s boys dominated the relays with wins in the distance medley {10:52.38) and the 4×800 (8:00.50). The Holliston girls captured the 4×800 (9:39.41) and Arlington took home gold in the distance medley (13:02.72).
