WICHITA, Kan. (AP) – Casey Wittenberg won the Wichita Open on Sunday for his second Nationwide Tour victory of the season, closing with a 5-under 66 in 100-degree conditions for a two-stroke victory over Justin Hicks and Jim Herman. Wittenberg, an eight-stroke winner in March in the Louisiana Open, finished at 18-under 266 at Crestview Country Club. He tied for 10th last week in the U.S. Open. “I wanted to go win the golf tournament and not let it come to me, “Wittenberg said. “It’s hard to win any golf tournament whether you win by one shot or you win by eight. It’s nice to have more than a one shot lead coming into the last hole and fortunately I was in that position coming to the last hole.” Wittenberg earned $108,000 to jump from 10th to second on the money list with $240,019. The final top 25 will earn 2013 PGA Tour cards. He also could earn an immediate promotion with a third victory. Hicks shot a 67, and Herman had a 70.
