Jockey Joseph O’Brien brought up a Navan double for his father Aidan and himself when guiding Plinth home by half a length in the mile and five maiden at Navan.

The 5/4 favourite hit the front over a furlong out, but was hard pressed all the way to the line by his market rival Mourani (7/4) on the inside. John Oxx’s Mourani had led throughout and didn’t give best until late on.

Jim Bolger’s Teocht kept on well into third to be beaten a length by the winner at odds of 12/1.

Plinth was nicely backed this morning from 9/4 to 6/4. Joseph O’Brien commented: “He’s improving with racing and got to the front a bit soon.”

Plinth holds an entry in the Group 2 King Edward VII Stakes at Ascot.
