Last 10 Preakness Winners. Oddity or Has Something Changed? (831 Views)

I find it very interesting the last 5 Preakness winners had NO negative numbers in their career prior to winning the Preakness. All these last 5 winners ran a winning Preakness number of 0 or higher, but none ran a negative number in winning the Preakness. For the last 5 years, the Kentucky Derby/Preakness winner(s) have had ZERO negative career numbers.

I also find it interesting that in the 5 year period prior, ALL Preakness winners had ONE or MORE negative numbers in their career prior to winning the Preakness. With the exception of Rachel all these winners won with a negative number in the Preakness. Rachel ran a 0 in winning the Preakness.

2014 CALIFORNIA CHROME NO negative numbers in career;
2013 Oxbow NO negative numbers in career;
2012 ILL HAVE ANOTHER NO negative numbers in career;
2011 Shackleford NO negative numbers in career;
2010 Lookin at Lucky NO negative numbers in career.

2009 Rachel WITH previous negative numbers prior to winning Preakness;
2008 BIG BROWN WITH previous negative numbers prior to winning Preakness;
2007 Curlin WITH previous negative numbers prior to winning Preakness;
2006 Bernadini WITH previous negative numbers prior to winning Preakness;
2005 Alex WITH previous negative numbers prior to winning Preakness.

(California Chrome, I'll Have Another, Big Brown won Derby and Preakness).
What has caused this change? If I missed a number somewhere, I'm sure someone will point it out.
