Switch to inside should do the trick for Rio

Quite a difficult card for punters tonight at Curraheen Park, where the feature is the final of the Boylesports Greyhound Derby Trial Stake, supported by the Laurels Restaurant A3 525 decider.

The nap goes to Carrigoon Rio, who looks drawn to take race three for Noel Casey.

Lightly raced but talented, he was having his first run back after a long absence when finishing fourth behind the improving Derrinasafa Spot here a couple of weeks ago.
