Ideally, Mason would partner with Fairfax County and build a new baseball stadium (with lights) similar to GW and Arlington County at Barcroft Park.
Years ago, Mason was approached by one of the Clark Griffith League summer league teams to split the cost to renovate the existing facility. Obviously, scheduling wouldn't be an issue. The athletic dept opted not to pursue the opportunity and the summer league team eventually partnered with the city of Vienna to renovate a field in town that now has lights and field turf.
Years later, Mason partnered with an area pro softball team to renovate the softball facility on campus. The softball team got out of the deal during construction and I believe that's why the grandstand wasn't extended from dugout to dugout. Instead, they planted grass on the slope where the seats were supposed to go.
New ballparks are being built in Loudon County (independent league team) and in Prince William County (Potomac Nats); I don't believe Mason was ever in conversations to share a new on-campus stadium with either team.
Why the administration hedged their bets on a pro softball team, but not an established summer league team or Potomac Nats, we'll never know. After the pro softball team situation, I can understand why they would be hesitant to partner with a new independent league team. There could be risk the team loses funding like the pro softball team did. But the Clark Griffith team and the P-Nats have been around for ages and it seems there would have been limited risk.
