Rachel Alexandra favored over Zenyatta

In the first odds I've seen on the $5 million Apple Blossom Invitational at Oaklawn Park on April 9, an off-shore wagering site lists reigning Horse of the Year Rachel Alexanda as a minus-145 favorite over Zenyatta.

Zenyatta, 14-0 lifetime, is plus-115, which means you'd have to wager $145 on Rachel Alexandra to get back $100 and a $100 wager on Zenyatta would return $115. Both horses must start for there to be action.

Of course, other horses will also be running in the Apple Blossom, meaning this is strictly a bet on which distaffer you believe will outfinish the other, no matter where both finish in the race.
