The tournament swung in Wittenberg's favor when Herman found the water with his second shot on the par-4 15th, decelerating on a wedge shot from 130 yards. After making double-bogey there, Herman then three-putted from 20 feet at No. 16 and his chances for a second career win on the Nationwide Tour were over.
"I knew 15 was playing short and Casey had just gone long with his second shot there. I just quit on my gap wedge and it went in the water. I'll remember that one for awhile. It was a pretty sad shot," Herman said. "The bogey at No. 16 was frustrating. I lost my focus from the previous hole and made a pretty bad putt. To play so well and give it all away on one shot was tough. I'll build off of it and try to get 'em next week."
Justin Hicks, trailing by three strokes at the start of the round, briefly tied Herman for the lead after making birdie from 14 feet at No. 13 just before Herman bogeyed No. 12. However, Hicks played his final five holes in even par to fall two strokes short of Wittenberg.
Wittenberg's win marked the second consecutive year that a player not only claimed his second victory of the season in Wichita but also won with the same score. Last year at Crestview Country Club, Mathew Goggin held off Kyle Thompson by one stroke with an 18-under 266 total.
Wittenberg became the first player since Scott Piercy in 2008 to win this event with a round in the 70s. It was the third time in tournament history that a player won in Wichita by two strokes and the largest victory margin in Wichita in four years. The victory came in his third appearance in Wichita. He missed the cut in this event in both 2008 and 2010.
