NEWMARKET'S Guineas meeting opens with a cracking card when the highlight will be the Group Two Grangewood Jockey Club Stakes. This mile and a half contest boasts a quality 10 runner field, including the Group One winner Luso, progressive stayer Celeric, Time Charter's useful daughter Time Allowed and the highly regarded Busy Flight.

And the latter looks the one to be on in this £50,000 added event.

Busy Flight makes his seasonal debut and the Barry Hills trained colt looks to have a bright future.

The son of Pharly and a close relation of five time Jockey Club Cup winner Further Flight is a late maturing sort who won his last three races in 1996, and Hills hopes his four year old can develop into a smart, middle distance performer this term.

From a family with a justified reputation for producing late developers, Busy Flight is open to further improvement and is napped to make the step up to Group class a successful one.

The Dubai operation is back in town and they can strike with Haltarra in the Kuwait Green Ridge Stables Newmarket Stakes over a mile and a quarter.

Haltarra, who shapes like a stayer, will appreciate the distance of the contest and can shake off his maiden tag.

Little Acorn stands out as the best bet at Musselburgh following impressive wins at Catterick and Carlisle.
