Simply put Zenyatta wasn't ready to run then..and it's very smart that her connections didn't force her, many great's have not run in all 3 Triple Crown races. Zenyatta had a segment on 60 Minutes Sunday, and if you didn't see it you can watch it on line at this link http://www.cbsnews.com/video/watch/?id=7009219n&tag=mncol;lst;2 I enjoyed the Zenyatta segment so much I watched it three times, plus the overtime footage on line, it was awesome, as well as, en-lighting. Everyone who spent time with her fell in love with her. One of the questions asked was as yours, "Why didn't Zenyatta run in the Kentucky Derby?" She wasn't ready, so she didn't race until late in her 3-year-old season. “You just had to wait for her to fill in and handle her size,” Shirreffs her trainer said. Not being ready the connections where right not to race her, a very smart move, and look at her size and you'll see why it was a long wait. At 17.2 hands tall, 1,217 pounds, Zenyatta is bigger than some draft horses. She's bigger than the legendary Secretariat, the one they called “Big Red” at 16.2 hands. She's bigger than Forego (17 hands) or Man o' War (16.2).
That size not only gave her a late start in racing, but it has dictated a late-running style. In every one of her 19 victories, Zenyatta has come from off the lead, most of the time circling the field on the far outside from well off the pace. It's a style that makes her perfect record even more improbable because of all the complications that can arise.
Despite traffic, slower-than-expected fractions from leaders, even at shorter distances than her preference, she always has managed to catch her competitors before the wire. Her style is very close finishes. Mike Smith her Jockey says she the best horse he has ever rode, and said she has another gear that he has never had the chance to use (yet)..but if needed it's there..watch 60 Minutes at the link above, you be happy you did..it will leave you smiling.. :)
