Last year’s Pennsylvania Derby (G1) winner Saudi Crown got back to his winning ways in Saturday’s $100,000 Tenacious S. at Fair Grounds.

I'm Very Busy showed a glimpse of his improving quality when a narrowly beaten second to the world-class filly Warm Heart in the Pegasus World Cup Turf (G1) in late January.

Flavien Prat engineered a massive upset in the $395,000 Wise Dan (G2) aboard 46-1 shot Stitched. The other two turf stakes on the Ellis Park card delivered chalky results, courtesy of favorites Wadsworth in the American Derby and Xigera in the Tepin S.
