The rubber match went Davis' way last Friday, as the Grizzly boys hoop team fell 67-63 to the Pirates.
The teams split a pair of close, hard-fought games earlier this season, but host Davis won the third tilt last Friday.
Sunnyside led early, grabbing a 17-12 first quarter lead. The Grizzlies clung to a 31-30 lead at the half and were up 46-44 after three quarters.
That all changed in the fourth frame as Davis grabbed the lead and never looked back, using a 23-17 run to escape with a win.
"We played well enough to win," said Coach Ruben Fernandez. "We played pretty good defense, but had a few breakdowns where we lost our guy and gave up perimeter shots (3's)."
Though Davis was able to shoot at a 36-percent clip from 3-point range (4-of-11), the Grizzlies actually had a sharper eye from long range and hit 41 percent (7-of-17). For the game, Sunnyside canned 41 percent of its shot attempts and Davis 38 percent.
Despite the Pirates' fourth-quarter surge, Sunnyside had a chance to tie the game late, but a travelling violation with 2.5 seconds left thwarted the opportunity.
The Grizzlies also hurt their chances for victory at the free throw line, as Sunnyside canned just 55 percent of its charity tosses, (10-of-18).
Trey Serl overcame a stomach illness to lead Sunnyside with 25 points. Greg Spini sparked the Grizzlies in the paint with 16 points and 11 rebounds. "Greg did a great job rebounding and posting up down low," said Fernandez.
The Grizzlies had a tougher time at Wenatchee on Saturday, as the host Panthers prevailed 57-28.
Sunnyside fell behind 13-3 in the first quarter and couldn't catch up despite pulling within 20-14 at the half.
The Grizzlies were still within shouting distance after three quarters, down 38-24, but a 19-4 Panther run in the final frame put the contest away.
"We just couldn't get into any offensive rhythm," said Fernandez. He noted Wenatchee went to a box-and-1 defense to stop Serl.
The ploy worked, as Serl was held to 8 points on 3-of-8 shooting.
Even so, Serl was still Sunnyside's leading scorer as the rest of the Grizzlies were a combined 5-of-46 - a shooting percentage barely over 10 percent.
"They did a great job and were very effective with it," Fernandez said of the Panther defense. "We didn't move around enough and didn't execute our sets to their gimmick defense."
To make matters worse for the Grizzlies, Wenatchee held them to one shot on most trips down the court. Sunnyside was outrebounded 37-21 for the contest.
Fernandez also gave credit to Wenatchee's offensive firepower
"In the second half, Wenatchee came out on fire. They had balanced scoring and regardless of what defense we were in they shot very well and had very few misses," Fernandez said.
Sunnyside (4-8, 6-11) hosts Eisenhower this coming Friday and is at home Saturday against Eastmont.
