Ohl put his stamp on ProRodeo in 1994 by winning Rookie of the Year and earning his first trip to the NFR. It would take Ohl a few years to win his first gold buckle. He edged out Fred Whitfield to capture the 1997 tie-down world title and roared through the 1998 season, capturing his second title. He had another record-setting year in 2001 as he added steer roping and team roping in order to compete for the All-Around title. In the ninth round of the NFR, Ohl missed his calf on the first loop. A second loop caught the calf by the hind legs. As Ohl dismounted, he twisted his knee, tearing two major ligaments. He had to be carried out of the arena by the Justin Sportsmedicine Team. However, he had amassed enough money earlier in the week to secure both the tie-down title and the All-Around title. He accepted both buckles from crutches on the 10th night. He went on to capture his fifth and sixth tie-down roping titles in 2003 and 2006. He still owns the record for the most NFR rounds won with 52.
