Rene Douglas, Arlington's leading jockey, won the first five races on Arlington Park's nine-race card Thursday and a total of seven victories from nine mounts on the program.Douglas' streak actually began with the final race on the Wednesday program when the 36-year-old reinsman guided Somethingdangerous ($8.00) to victory, his third on that card and meet leading 68th win entering Thursday's races. The Panamanian-born rider then rattled off scores in the first five races Thursday, taking the opener aboard Stormy Rosa ($5.20), the second with Excellabet ($7), the third astride Uncontrollable ($6.20), the fourth on Quest For Truth ($4.20) and the fifth with Willow Cove ($7.40). The skein came to a close when his sixth-race mount, One More Moondance, finished fifth, but he quickly rebounded to take the next two races -- winning the seventh with Red Mimi ($3.20) and the eighth on Chirimoya ($3.80). His ninth-race mount, Marnita, finished third.Douglas, who now has 75 wins at the meet, leads his closest pursuer Eusebio Razo Jr. by 27 victories.

program, recorded by Pat Day on September 13, 1989.
