Collectively, the Motts hewed to character in their press appearances, where they have been their understated, wry selves addressing the most rare father-son casting.

But before we get into what Mott, Alvarado and Chief Wallabee have to do tomorrow to take down Renegade and Commandment, herewith, a refresher on the newly revised field. Note: revised post positions appear here in parentheses ONLY for those eight outside horses whose stalls and saddle cloths do not correspond. For the twelve inside horses whose saddle cloths and post positions still correspond, no change is made.

Of Chief Wallabee’s three races, in two of them — February’s Fountain of Youth and March’s Florida Derby — he has faced Commandment quite commendably. In the Fountain of Youth, he ran a very close place by a neck to Commandment.
