Ballpark Info

The Clinton LumberKings have been playing at their current ballpark since the stadium's construction in 1937 as a project for the Works Progress Administration during President Franklin Delano Roosevelt's administration. Situated on the banks of the Mississippi River in downtown Clinton, the stadium has had four names. From 2002 through 2011 the park was renamed Alliant Energy Field, from 2012 through 2018 the park was known as Ashford University Field, and starting in 2019, the stadium is named "NelsonCorp Field." The stadium is the second oldest park in the Midwest League and has undergone just one major renovation since its creation. Construction of the historic facility began in 1935 and lasted less than two years with the inaugural game played on May 9, 1937. The park was designed by Albert H. Morrell and Associates with Fred N. Grumstrup hired as the general contractor with the entire cost of construction coming to $150,000. The 1937 design is still the prominent look of the park and is modeled in the art deco style which was popular at the time. 2,500 of the park's 5,000 seats are located underneath a canopied grandstand, a feature that is unique to Clinton and the Midwest League. A $3.8 million renovation in 2006 added new offices, a new home clubhouse, an upgraded patio/playground area, and a new playing surface.

If it is raining at the ballpark before the start of a game, the LumberKings Grounds Crew is hard at work protecting the field against the elements. Because of this, if the rain stops before the game's scheduled start time, the game will continue as planned. If the rain continues into the scheduled game time, LumberKings management will invoke a rain delay.

If it begins to rain during the game, the LumberKingsGrounds Crew will quickly cover the infield with a large tarp. At that time, game officials will work with local weather outlets to ascertain the immediate weather outlook. If game officials feel that the inclement weather will pass, a rain delay is put into effect. If game officials feel that the inclement weather will not pass in a reasonable amount of time, an official rainout will be announced.

If a game is called by rain or inclement weather, your ticket stub may be exchanged for any future game ticket, subject to availability.  No refunds will be given after an official game (either 4 ½ or 5 innings) or for delayed or suspended games.

If a game is rained out, the local media will be notified and asked to broadcast the information.  Also, check our web site here and follow @LumberKings on Twitter for the most up to date information regarding weather events and game details.
