Beyer: Lack of competing speed puts American Pharoah in driver's seat


American Pharoah’s final race, the Breeders’ Cup Classic, was supposed to be the test that measures how great a horse he may be. He has already earned a place in history by sweeping the Triple Crown, dominating a 3-year-old crop of average quality. But 3-year-olds don’t fully prove themselves until they face older rivals, and plenty of formidable ones were entered to challenge American Pharoah on Saturday at Keeneland – the champion mare Beholder; the powerful stretch-runners Honor Code and Tonalist; the brilliant, tenacious speedster Liam’s Map.
