Stevenson's softball field had yielded just two over-the-fence home runs before this season.
On Tuesday, Carmel Catholic's Jenny Behan become the third player to pull off the feat this season.
"That's 3 in like in 2½ weeks," said Stevenson coach Larry Friedrichs, whose own Abby O'Connor on Saturday became the first player ever to hit two over-the-fence homers (both this year) at the Patriots' field.
Behan's shot, which cleared the 255-feet sign in center field, helped lift Carmel to a 14-10 win in a nonconference slugfest that featured 26 hits.
"It was a line-drive shot," Friedrichs said.
Behan, a sophomore who's already committed to play Division I softball for James Madison, also tripled, driving in 2 runs on the day. Kathleen Felicelli (2-for-4) and Sarah Koesser (3-for-5, 2 doubles, 2 runs, 4 RBI) also had big days at the plate for Carmel (14-5).
Taylor Koenigs homered for Stevenson (11-8). Koenigs (3 RBI, 3 runs), Dana Morgan (2 runs, RBI) and Trisha Porzycki (RBI, run) each went 3-for-4 for the Patriots. Lexi Yonkovic and Jordan Cortesi (RBI, run) had 2 hits apiece.
Nicole Bitter earned the win over Sam Feder, who allowed 10 runs (3 earned). Carmel wiped out a 3-0 deficit by scoring 9 runs in the third inning.
