For the second straight day Newton North junior Carla Forbes excelled on a national stage. Forbes won the long jump title Saturday at the New Balance Outdoor Track Championships, her second national title at the event in Greensboro, N.C. Forbes won the triple jump Friday. And she wasn’t alone on the victory stand, as Marshfield’s distance medley team also won.

“It just absolutely amazes me that she keeps pulling this off,’’ said Newton North coach Joe Tranchita, referring to Forbes. “She just looks so seasoned. The other kids jump, but just don’t have her technique.’’

Forbes jumped 19-9 1/2, better than her winning All-State distance earlier this month of 19-1, but below her personal best. Forbes had six jumps, three in the preliminary round, three in the finals. She hit the winning distance in one of her final jumps.

“Her board placement was perfect,’’ said Tranchita, who has talked to coaches at Duke, Florida State, and Kentucky who are interested in Forbes’s talents.

The Marshfield team of Kevin Thomas, Joe LaSalle, Ryan Talanian, and Joel Hubbard won the national title in 10:01.32. Pembroke was second in 10:02.13.

Mansfield’s Jen Esposito was third in the 400-meter hurdles, clocking in at 1:00.35. Esposito’s time was almost two seconds faster than her All-State winning time earlier this month of 1:02.17. She is headed to Elon University in the fall and will compete on the track team.

The Acton-Boxboro 4 x 400 team of Brian Sommers, Dominic Abacherli, Eric Nord, and Nick Usoff finished second in the emerging elite race, clocking a time of 3:22.37.

Somerville’s Andre Rolim was fourth in the 800 Emerging Elite at 1:55.06.

In the girls’ 4 x 1 mile relay, the Lincoln-Sudbury team of Marika Crowe, Sydney Clary, Brianna Bisson, and Katie LaScaleia finished sixth in 21:17.5. Close behind were teams from Acton-Boxboro (seventh in 21:22.17) and Hamilton-Wenham (eighth in 21:28.28). Bishop Feehan was 13th in 21:53.60 . . . Westford’s state champion pole vaulter Brendan Sullivan was eighth in the event at 14-2 1/2 and Wakefield senior Elizabeth Bray was eighth in the shot put at 41-1.
