CD East had been a thorn in Cumberland Valley's side for more than two seasons.
The Panthers had won six girls' basketball games in a row against the Eagles, including a 40-37 win on Dec. 18.
Cumberland Valley brought an end to that streak in a big way on Wednesday night, defeating CD East 56-28.
Although the win broke their losing streak to the Panthers, the first thing the Eagles were concerned about was setting themselves up for a second-straight Mid-Penn Commonwealth Division title.
"As we prepared for this game, and even in the talk before getting out there tonight, our focus wasn't on getting one win over East," Cumberland Valley head coach Bill Wolf said. "We were focused on that we needed to win to repeat as Commonwealth champions."
Now that the Eagles are 10-1 in the Commonwealth and the Panthers are 6-3, the title is not clinched, but Cumberland Valley is in an enviable position.
But for the game itself, Cumberland Valley had eight players score field goals, whereas there were only five Eagles who scored from the floor in the loss in December.
"Offensively, our execution was a lot better," Wolf said. "We got contributions from a lot of girls. With those contributions, our field goal percentage was a lot better than the 29 percent like the last time we played them."
Rebounding was also a big factor. Last time, CD East had a 33-24 rebounding advantage. On Wednesday, Cumberland Valley won the rebounding battle 41-24.
In addition to ending a long stretch of Panther wins over the Eagles, the game also ended a run of close games between the two squads. Along with CD East's 3-point win earlier this year, the Panthers had three 2-point victories over Cumberland Valley last season.
Cumberland Valley jumped out to a 13-0 lead late in the first quarter on a jumper by Jen Falconer and maintained a double-digit lead the rest of the way.
Not that the early deficit caused CD East to quit.
"Two years ago we were behind 21-2 in this place," Panther head coach Charlie Harvey said, referring to one of the wins in the streak. "Last year at our place we were down 16-0."
But eventually the lead simply became too large and the time remaining too little. A 3-pointer by Taylor Sneidman and a free throw by Falconer made it 24-4 in Cumberland Valley's favor late in the second quarter.
