It’s not often a high school athlete steps into a brand new sport and proceeds to compete at the highest level almost immediately.

Not often, but not unheard of.

In her first indoor track season, Norwell’s Liliana MacDonald has made the long jump her event and she did it again Sunday at the Coaches Small School Invitational at the Reggie Lewis Center.

The Clipper senior continued her streak of torrid long-jumping with her decisive 17-7 1-2 win on the runway. MacDonald picked up a second medal in the 55 hurdles where she finished third in 8.78 seconds.

Head coach Chuck Martin is confident she’ll break 18-feet this season.

“She’s just really consistent in the long jump,” said Martin. “There hasn’t been a meet this season where she’s been under 17 feet. She did a little hurdling outdoors last spring. She’s accomplished a lot in the hurdles on very little training because of the snow.”

The Clippers just missed qualifying for the nationals in the 4×400, but the lineup of Brody McVayl, Noah Mulligan, Griffin Murphy and Sam Pesko is on the verge with a 3:29.85 win.

“They were hoping to get the national standard, but they’ll get it,” said Martin. “They’ve got a lot more in them.”

Ludlow’s Logan Walsh used what can be a dicey strategy in the mile by building a 30-meter gap after the half mile and challenging the rest of the field to match his brazen move. Walsh was very much up to the task against the talented field. The junior surged across the finish line with a new personal best of 4:26.27. Attikos Kaye of Somerville closed hard and picked up his own personal best at 4:28.64.

But it was a freshman in the girls’ mile who really raised eyebrows on the oval in arguably the best performance of the meet. Billerica’s Gianna McGowan had no intention of staying back while the older, more experienced runners set the tone for the race. Instead, the young, smooth-striding upstart took the pace for the first 800 to string out the pack, and only then surged hard and built nearly a half straightaway lead. McGowan broke the tape with an impressive 5:08.15. That time bettered her previous mark by nearly five seconds and is the No. 5 best in Massachusetts this winter.

The real race was for second as Westfield’s Megan Moran (5:13.58), who also raced to second in the 2-mile, edged out Wakefield’s Lily Sallee (5:13.92) and Ella Dunbury of West Bridgewater (5:14.86).

Bromfield’s Jack Stahl looks as though he’ll be one of the strong favorites when the division championships roll around after a dominant win in the 600. Stahl’s stride was smooth from the gun as he raced to the No. 6 time this winter and a personal best of 1:22.87 for the easy win. Nashoba’s Connor Acierno was second in 1:24.63 and Miguel Pinero-Jacome of Amherst-Pelham clinched the bronze medal with a 1:24.94.

Coming off a monster day at the Div. 3 Coaches Relays, Billerica’s Ryan Leslie dueled with Isaac Gross of Marblehead and kept him at bay for a Massachusetts best this winter, 9:22.87. Gross’s 9:27.85 was good for No. 2 this winter. On the girls’ side, Ila Zollo of Walpole cruised to a personal-best 11:16.77 win.
