Of the two, Decker’s scorecard was certainly more colorful. He opened with birdies at Nos. 1 and 3, added a bogey at No. 5, then went birdie-eagle to close the front nine. On the back nine, he mixed four birdies with two bogeys. Decker played for the University of Wisconsin from 2014-17.
Behind the leaders, Ryan Isaacson of Eau Claire and Samuel Anderson of Stoughton are tied for third at 5 under. The leaderboard remains cramped from there – the top 20 players all posted a round in the red on Monday.
Defending champion Matt Tolan struggled in the opening round, posting a 5-over 77. Tolan had two double bogeys on his card and ended his day with a bogey at No. 18.
