Kansas University’s Frank Duncan grounded Air Force from the mound, and the Jayhawks held off the Falcons for a 5-2 victory on Friday night in the Jayhawk Classic at Hoglund Ballpark.

Kansas third baseman Jordan Dreiling throws out Air Force's Alex Bast at first during Kansas' game against Air Force Friday, May 4, 2012 at Hoglund Ballpark.

Duncan, KU’s sophomore starting pitcher, worked eight innings and allowed just one earned run on six hits. He struck out nine and improved his record to 5-6. Robert Kahana earned his first career save.

Alex DeLeon led the Kansas offense from the beginning, launching a home run in KU’s three-run first inning. He finished the night 3-for-4 from the plate with a double and two runs scored.

The Falcons narrowed the Jayhawks’ lead to 3-2 in the top of the sixth inning, but DeLeon and company capped off the inning with two more runs of their own.
