The victory, their 12th against eight losses, was the final feather in the regular season cap of a Lady Wolverines team that saw them win only two games just two short years ago.
Now they've claimed a piece of the Southwestern Indiana Athletic Conference crown -- one they will share with the winner of Thursday's North Daviess at Eastern Greene game -- and head into next week's Class A sectional at Clay City as one of the teams to beat.
"This has been a great year," WRV coach A.J. Graves said. "It's nice to keep building on that and keep moving forward.
"Just like I said about the Linton game, the worst thing we could do was take steps back right before sectional -- and I don't think we did that.
"We're still getting better each and every day and I'm starting to see more and more good things and less mistakes."
About the only thing that didn't go right for the Lady Wolverines on Wednesday night was when they lost the opening tip -- twice.
After the jump was tied up almost immediately between Washington Catholics Hannah Wild and WRV's Madison Hockman, it was re-tossed between the two and Wild controlled the tip.
"I don't think we've ever got the opening tip," Graves said chuckling. "And I didn't know it was even a rule in high school basketball."
From there it was a display of offensive superiority and defensive effort that kept the Lady Cardinals reeling. Reeling until the lead finally reached the 30-point margin WRV flirted with during the second half.
"We played pretty well," Graves said. "From a coaching standpoint there's a lot of little things I could pick on and I will.
"Because the way this team is going now we're going to have to start getting minute about the details. But in the big picture things it's going good, we're starting to clean things up.
"It's been three years in the making, since I've been here we've been steadily making progress toward a successful season and we did that this year with a winning record and now it's time to ready for serious business at the sectionals next weekend."
WC never scored more than six points in any quarter but the fourth. WRV led 20-6 after one quarter, 34-11 at the intermission and 46-16 at the final stop.
If not for Graves and company turning down the dial in the fourth quarter the game could have been even more of an embarrassment to the Lady Cardinals who head into their season finale with a 2-19 record.
As a team WRV shot 22 of 52 from the field and 5 of 19 from 3-point range. Their offensive dominance in the game was never prevalent than in the first quarter when they misfired only once -- and it came as the buzzer sounded ending the period.
Over the opening eight minutes the Lady Wolverines went 8 for 9 from the field and 2 for 2 from the charity stripe.
"We haven't done that over the last few games," Graves said. "I told the girls you have to keep putting them up and you have to be ready to shoot.
"I've seen them hit plenty of them in practice, so it was just getting them to carryover into the game. I felt like it would be coming and it was nice to have that today."
On the glass it was much the same story as WRV held a distinct advantage. Led by the game-high eight boards from Jasmine Padgett, the Lady Wolverines took home a 34-23 advantage.
When it was all said and done three Lady Wolverines finished in double figures. Maddy Dyer led the way with 11 followed by Allison Wininger and Shannon Pittman with 10 each.
Amy Ragle added nine, Lexi Graves seven, Megan Lemmons four, Briauna George-Fisher three, Jasmine Padgett two and Hockman one.
"It's a nice finish to the year no doubt," Graves said. "I'm very proud of our seniors Maddy and Megan, they've done a great job for this program."
Next up for the SWIAC co-champs and are the host Clay City Lady Eels on Friday, Feb. 8 at the Class A Sectional. They will tip-off the semifinal round with a 6 p.m. start.
There was no junior varsity at the request of the Lady Cardinals.
