O'Brien's Navigation Stakes pair both hold strong claims Trainer Joseph O'Brien, who has been amongst the winners in recent days, has two strong contenders for the Listed Navigation Stakes at Cork on Tuesday. O'Brien, who enjoyed an across the card treble at Down Royal and Roscommon respectively on Monday, sends Wigmore Street and Goldana to Mallow for the one-mile contest. Stable representative Sean Corby said: "The horses are running really well and the two of them should have a good chance. "Wigmore Street has been in good form of late, so he should have a good chance. I think since they have just started to ride him with a bit of cover, it has really brought out a lot of improvement in him. "The more rain the better for Goldana. Obviously, she is getting a little bit older now and probably just minding herself a bit and the (first-time) cheekpieces should just bring out improvement." Additional reporting by Michael Graham.
