School record-breaking vaults from Marin Arsenault and Rachel Goding helped the Plant girls to a narrow win against Alonso at the Nash Higgins Relays, the annual Hillsborough County relay meet.
Arsenault and Goding both cleared 10 feet, 6 inches, a Plant record, placing them behind only Brittainey Smith of Wharton, who cleared 11 feet. But with relay-style scoring in effect, Plant earned the win in the event, in addition to first-place finishes in the 4x800 and distance medley relays, and a tie for first in the high jump.
Plant coach Roy Harrison said, "It was a very good jump for this time of year for both of them. They did awesome."
Plant totaled 63 points to Alonso's 60. Wharton was third with 55.
"I scratched the 4x400, and then tried to strengthen the (other events) a little bit," Harrison said. "It worked. I wasn't expecting it."
Freedom senior Sandra Akachukwu had the highest marks in the high jump (5-2) and long jump (17-7).
High winds and temperatures in the mid-50s led to slower than expected times. Still, Wharton and Alonso broke 4:10 in the 4x400, with Wharton earning the win, 4:08.77 to 4:09.40.
Steinbrenner was first on the boys' side with 56 points, over Hillsborough and Armwood, who tied for second with 53.
Wins for Steinbrenner came in the 4x800 (8:19.49) and shot put. They placed second in the 4x100 and distance medley. Hillsborough won the 4x100 in 42.72, just ahead of Steinbrenner in 42.98. Lars Venner anchored Newsome to a come-from-behind victory in the distance medley in 10:52.45.
"It's a great meet to learn where our kids compete, and where they stand with everybody else," Steinbrenner coach Michael Bosco said.
Hillsborough's Jeremiah Green, the defending national champion in the triple jump, competed in the long jump, leading the field with a mark of 21-0.
