The Buckeyes defeated Minnesota in the WCHA Semifinal, 4-3, in overtime. Dunne was credited with the assist on the game-winning goal which sent Ohio State to its second WCHA Championship in program history.
Ohio State defeated No. 1 Wisconsin, 1-0, in overtime. Dunne was once again credited with the assist on the game-winning goal, making her the program record holder for career postseason points and assists.
Dunne was named to the WCHA All-Tournament team after notching six postseason assists.
Ohio State earned the league's automatic bid to the NCAA Tournament. It would be the Buckeye's second NCAA appearance, both during Dunne's tenure.
"Together we made history. From now on, when I think of my last game in a Buckeye uniform, I'll remember us beating Wisconsin in overtime and how amazing of a feeling it was to win our league. That's so incredibly special and something I'll hold on to forever."
To start the 2019-20 campaign, Dunne was the only unanimous coaches' pick for Preseason All-WCHA honors. She continued to shine throughout the season and was a two-time Defenseman of the Week and two-time Defenseman of the Month. In February, Dunne was named First Team All-WCHA for the third year in a row, one of only two Buckeyes to do so.
In March, Dunne made history once again as she was named the WCHA Defensive Player of the Year for the second year in a row. It marked only the fourth time in WCHA history that the same player has earned the award in back-to-back years.
A two-time team captain and two-time alternate captain, Dunne became the only Buckeye to be named First Team All-USCHO after receiving second and third team honors during her junior and sophomore seasons, respectively.
Dunne finished her career as a Buckeye just shy of 100 points, tallying 17 goals and 82 assists. Her 99 points put her third in Ohio State history for career points by a defenseman while she ranks second in career assists by a blueliner.
"I've spent the last five years around some amazing girls and I'm forever grateful that my journey allowed me to be apart of that."
