The Oklahoma Derby had a working list of seven early probables on Monday, with a handful of leading contenders scheduled to arrive at Remington Park on Wednesday. The Grade 3, $400,000 race will anchor a card of 10 stakes on Sunday. Battle of Midway, the third-place finisher in the Kentucky Derby, is scheduled to fly in Wednesday along with fellow Southern California-based probables B Squared and Gato Del Oro, said Don Thompson, stakes coordinator for Remington.
