Gary Hallberg shot a scintillating 11-under 61 in the final round last year to win the Greater Hickory Classic at Rock Barn.

It gave him an 18-under 198 total -- tying the record at Rock Barn Golf and Spa -- and his first career victory on the Champions Tour. As good as Hallberg's round was, the win didn't come easily. With Fred Couples and Bernhard Langer in pursuit, Hallberg had to grind to the finish. In the process, he set or equaled a number of Champions Tour standards.
Hallberg is back to defend the title this year and, ironically, neither Couples, the runner-up by one stroke in 2010, or Langer, who finished third, will be in the field. Both are recovering from physical issues. Bob Tway, who shot a final-round 62 to finish fourth, is back looking for his first Champions Tour title. Tway's round included an ace at the 186-yard ninth hole at Rock Barn.
Jay Haas is a two-time winner of the Greater Hickory Classic in 2005 and 2009.
