Shaw, an outfielder from Mount Vernon, Ohio, posted an outstanding career at Mount Vernon High School that included being named to the Ohio Capital Conference First Team as a junior and senior and becoming the first player to ever be named to the Mount Vernon News All-Area First Team all four years. She was also named to the Columbus Metro Area Second Team as a junior and the Central District First Team and Team Most Valuable Player as a senior. She compiled a .417 batting average with 12 stolen bases and a team-high 21 RBI as the lead-off hitter her senior year for the Yellow Jackets.

"We are very excited to add Mackenzie to our team,” said MVNU head coach Jeana Howald. "We needed to add depth to our outfield and MacKenzie is quick and has a good arm. One of the things I really like about her is that she communicates very, very well. She will be successful at our level. With her personality and skills, she will be an asset to our program.”

In addition to playing softball at Mount Vernon High School, Shaw has been a member of the Lady Lasers Blue traveling team for several years and has helped the team compile a 269-70-5 record while batting .430 with 290 runs scored and 227 stolen bases during that span. She has also been active in Fellowship of Christian Athletes, Student Council, and Forum book, and she served as a D.A.R.E. role model. In addition, she received the Teacher Academy Student of the Year award as a senior.

"I wanted to go away and I said that I would never go to a college so close to home,” said Shaw of her college choice. "However, the Christian atmosphere at MVNU is what I wanted, the softball is great, and I want to go into education. (MVNU) has one of the best education programs in the state.”

MVNU is an NAIA school that competes in the American Mideast Conference. The Lady Cougars posted a 26-20 overall record in 2008, and the program has an all-time mark of 551-370-2 in the 24 years of the program’s history. The team also advanced to the championship game of the NAIA Region IX Tournament in 2008 for the first time ever despite entering the tournament as the fifth seed in the seven-team tournament.
