The World of Outlaws Sprint Series is invading Las Vegas this weekend to close out its 28th season, one of the most competitive in series history. With a preliminary feature at the Dirt Track at Las Vegas Motor Speedway on Friday followed by the main event on Saturday, there have been 22 different drivers to visit Victory Lane this season with the Outlaws, 17 in a main event. Steve Kinser has led the way with 20 A-feature victories — winning most recently on Oct. 11 at Manzanita Speedway — in addition to his six prelim victories. Twice this season he has swept a weekend event, both times at Eagle Raceway when he won the Eagle Nationals in June and the 1/3-mile Short Track Nationals in September. He also swept the Knight Before the Kings Royal and the Kings Royal, which were separate events in terms of points but run on back-to-back nights in July at Eldora Speedway. Perhaps Kinser's most remarkable accomplishment this season was in the first race after the Knoxville Nationals when the series raced on a Tuesday at Red River Valley Speedway in West Fargo, N.D. On that night Kinser was the fastest qualifier, won his heat, won the Stacker 2 Dash and led all 30 laps to win the A-main. He was the only driver this season to sweep every facet of a single event. But ask Kinser what his highlight of the season was and he'll point to the Knoxville Nationals, where he finished seventh … as a driver. Of course, that August night belonged to Kraig Kinser, his son who drove a second Steve Kinser Racing Maxim to victory on sprint car racing's grandest stage. When the Outlaws raced in March at Las Vegas, Kraig Kinser captured the preliminary and was the runner-up in the main event to Donny Schatz. Schatz, who won the 2004 season finale at Las Vegas as well as the March event there, has won eight World of Outlaws A-feature events this season — second-most in the series — as well as the preliminary on Friday at Thunderbowl Raceway in Tulare. Schatz has been one of the strongest racers down the stretch as he gears up for the 2006 season with the Outlaws. In fact, in the past 10 events, he has finished outside the top five only once, winning three A-features and a prelim. Next up on the win list is Kraig Kinser, who has six A-feature victories and the preliminary win in March at Las Vegas. Clearly, no win was bigger than his $140,000 victory in the Nationals, but Kinser also won two the three World of Outlaws events this season on quarter-mile ovals in his native Indiana, with father Steve winning the other. Daryn Pittman, another of the drivers set for the 2006 season with the Outlaws, came on strong at the beginning of August and carried the momentum through the West Coast swing before putting together back-to-back A-feature wins in late September at Jackson Speedway and The Raceway at Powercom Park. In all, Pittman has five main-event wins this season. Jason Meyers put together a career year, highlighted by his four main event victories and 49 top-10 finishes. Meyers is aiming for a strong finish to the season at Las Vegas, where he posted a top-10 run in March. Three of Meyers' wins came on half-mile ovals like the one at Las Vegas. Three time winners this season included Tim Shaffer and Sammy Swindell, who captured the feature on Saturday at Thunderbowl Raceway in Tulare, Calif. Shaffer broke through for the biggest win of his career in July when he raced to victory in the $30,000 Don Martin Memorial Silver Cup at Lernerville Speedway, a track where Shaffer was champion in 1993. Swindell, a three-time World of Outlaws champion who raced 46 times with the Outlaws this season, added two preliminary feature victories to his total, as well. Danny Lasoski and Brian Paulus, as well as 2006 Outlaws Craig Dollansky and Brooke Tatnell, all won two A-feature events in 2005. In addition, Lasoski grabbed two preliminary feature wins, one of which helped him sweep the Cowtown Showdown at Dodge City Raceway Park. Tatnell and Paulus each had one preliminary feature victory, with Paulus' coming in the next race after his second main-event win. Pennsylvania legend Fred Rahmer won the Summer Nationals crown at Williams Grove and added preliminary feature victories at Knoxville Raceway and another at Williams Grove. Jac Haudenschild, Stevie Smith, Tim Kaeding, Chad Kemenah and Jeff Shepard all won an A-feature this season while Joey Saldana, Paul McMahan, Jason Johnson, Kerry Madsen and Shane Stewart all won a preliminary feature in 2005 The season finale this weekend will mark the 38th and 39th times the Outlaws have raced on a half-mile oval. Steve Kinser leads all drivers with 10 victories this season on half-mile circuits, and has won three A-feature events in his career at Las Vegas.
