The lightly raced Pneumatic enters the Belmont Stakes off a third-place finish in his graded stakes debut in the Grade 3 Matt Winn on May 23 at Churchill Downs.
The son of Uncle Mo won his debut over the Oaklawn Park main track, defeating next-out winners Skol Factor and Liam’s Pride. In his following start, he bested stakes-winner Captain Bombastic by 2 ½ lengths on April 11 over the Hot Springs oval.
A Kentucky homebred, Pneumatic is a direct descendant of Carols Christmas, who was claimed for $25,000 and went on to become a foundation ‘blue hen’ mare for Winchell. Graded stakes winners Pyro, Olympio, Call Now and Cuvee are all from the same family.
Asmussen will attempt a second victory in the Belmont Stakes after having saddled Creator to a 16-1 upset win in 2016.
Asmussen and Winchell sent out Tenfold to a fifth-place finish in the 2018 Belmont behind Triple Crown-winner Justify.
