All 19 horses in this year's Kentucky Derby have a common horse in their lineage. This horse has also won a Kentucky Derby. Which horse?

Secretariat - or as Kruk & Kuip called him, the Wilt Chamberlain of the horse world.

Correct! Secretariat/WC won the Kentucky Derby. And the Preakness. And the Belmont Stakes. All in the same year...

Secretariat set speed records at each distance (KDerby, 1 mile; Preakness, 1 1/4 mile; Belmont, 1 1/2 mile) in all three races and won the Belmont Stakes by a record 31 lengths, in a still-existing record of 2:24. Secretariat also holds the fastest 1⁄2-, 3⁄4-, 1- and 1+1⁄4-mile fractions in Belmont history.
