PORTLAND, Ore. (AP) — Road-course ace A.J. Allmendinger survived the NASCAR Xfinity Series’ wet and wild Portland International Raceway debut with a victory Saturday. Allmendinger raced to his Xfinity-record eighth victory on a road course and 12th overall series win. He crossed the finish line in the Kaulig Racing Chevrolet 2.879 seconds in front of Myatt Snider. The 75-lap race on the 12-turn, 1.97-mile permanent road course north of downtown started in heavy rain, resulting in slippery conditions. It was first NASCAR event in the region in 22 years, and a rare stand-alone event for the second-tier national series. There were nine caution flags and eight lead changes in the race that looked at times like a demotion derby with several spinouts, bumps and wrecks.
