Bull rider Aaron Pass has been bullish here lately.On the weekend of Jan. 2-4, the Dallas cowboy won all three rounds of the Professional Rodeo Cowboys Association Ram Texas Circuit Finals in Waco. As a result of that big victory, he will advance to the Ram National Circuit Finals Rodeo, which is scheduled for April 10-12 at the Lazy E Arena in Guthrie, Okla.While competing at the Fort Worth Stock Show’s Bulls’ Night Out performance on Tuesday night, Pass took the lead in the title race after turning in scores of 86 and 89 during a sold-out performance at Will Rogers Memorial Coliseum.“It’s been outstanding,” Pass said of his booming start to 2014.While competing at Bulls’ Night Out, which is part of the PRCA’s Xtreme Bulls circuit, Pass turned in a first-round score of 86 atop a bull named Plaid Shirt, owned by the Smith Harper and Burruss Rodeo Co.“That bull has been around a little while and he really bucks,” Pass said.During the 8-second ride, the bull vigorously spun to the left.“When he bucks, sometimes he spins and then jumps out of it,” Pass said. “But this time, he stayed hooked.”After turning in the 86, Pass was among 10 bull riders who advanced to Round 2. During the Short Round, Pass turned in an 89 aboard a bovine named Haunted Mesa, owned by the 4L and Diamond S Rodeo Co.“He spun to the right. He had me in an out and I had to work a little harder than I wanted to,” Pass said.Pass finished with a two-ride score of 175. Sam Matthews of Springdale, Calif., is ranked second with a 166 and Dylan Vick of Escalon, Calif., is No. 3 with a 162.The second and final performance of Bulls Night Out is scheduled for 7:30 p.m. Wednesday.
