Talk:Kelso (horse)

Can someone explain start of 3-year-old season?
I am seeing:

"Kelso's three-year-old season began after the Triple Crown races of 1960 were run."

Please explain this. Do some horses go through 3-year-old season out of synch with the Triple Crown races? — Preceding unsigned comment added by 128.63.16.47 (talk) 18:57, 12 June 2015 (UTC)
