The Clinton LumberKings, a Single A affiliate of the Seattle Mariners, play at Alliant Energy Field, formerly Riverview Stadium that was built in 1937. The stadium received a major upgrade in 2006 with seating for 4,000. All new picnic area, children's play area, and player clubhouses down the 3rd baseline. The stadium is very close to the Mississippi River. You can see a gambling riverboat over the fence. Clinton was playing the West Michigan Whitecaps and won 9-4. The box score was Whitecaps R-4, H-8, E-3, and Lumberjacks R-9, H-8, E-1. The field lines are RF-325', RC-401', CF-395', LC-335', LF-330'. One mid-inning activity is two children riding small pedal John Deere tractors. Louie is the mascot. There is a very good selection of food for this level of baseball. Great Root Beer Floats with lots of ice cream. Jim was able to get a 2010 team autographed baseball for only $15. Regular player autographed baseballs were the same price. We attended the game with Andrea's cousin and her husband. 2014 Ashford University Field. 2019 affiliated with Miami Marlins. 2013--2021-Team affiliates with Colegiate Prospect League.
