Let's face it. There's no logical reason Rock'n Boy keeps winning, but it's time to quit betting against him. His background suggests cheap speed, good cheap speed, but cheap nonetheless. Now, he's won all six thoroughbred starts this year and has paid generous prices. He probably won't be favored in tonight's fifth race, either.
The truth is, at age 5, he may just be finding himself. How else do you explain his march through the claiming ranks, winning under jockeys who seldom win and beating horses with better lines? He even runs well in the mud. So does Sir Tiger K., but that late bloomer has been off for seven weeks.
