Since Affirmed completed the Triple Crown in 1978, 12 horses have won both the Kentucky Derby and Preakness Stakes. The first 11 failed to win the Belmont. I'll Have Another will attempt to break that streak on June 9th.
If you're looking for a horse racing wager before the Belmont, challenge a friend to see who can name more of the 11 Derby/Preakness winners who preceded I'll Have Another. You've got 3 minutes.
