Ace show rider Rodney Jenkins of Orange, Va., captured both championships in the novice hunter division today at the Middleburg National Horse Show.

Emeralda Farm's 3-year-old filly Looking Good won two classes over fences for 10 points toward the championship title in the novice hunter A section, which had to be divided because of the large field of 118 horses.

Patrick Saltz rode his Stolen Roses to the reserve title with seven points.

In the B section, Jenkins piloted Superman, owned by H. R. Sherman and Hilltop Stables, to victory with six points after placing second two times to Sally Oliver's One Martini and Donnarry Farm's Radar.

Superman, a 6-year-old chestnut gelding, is a recent acquisition to Jenkins's string. According to Cathy Simm, who rode the horse in the hack class for Jenkins, "I couldn't tell you much about him. We've only had him in the barn one week."

One Martini and Radar were tied for the reserve title with five points and were called back to hack off. Eventually Radar, a 4-year-old brown gelding ridden by Jane Flynn of State College, Pa., took the title.

In additional to his victory in the hunter division today Jenkins also won a class in the preliminary jumpers on Joe Fiori's Fair Cast.
