Preview navan 8th Jul Ger Lyons has a trio of interesting challengers at Navan, starting with Roibeard in the opening Country And Western Evening Claiming Race at 5.40.The Big Bad Bob gelding won with some ease at Fairyhouse last time and is miles clear of his rivals on official ratings, though Braver the Bull and Brontide both get more weight from his than they would in a handicap.Lyons takes the wraps off an intriguing newcomer in Bromance, who is related to a couple of winners and makes his belated debut in the Lynn Lodge Stud Maiden.There are a number of potentially talented individuals in opposition, though, with Dermot Weld reaching for blinkers for Look Closer, who has run a pair of solid races so far, while Jim Bolger runs debutant Seville Star, who fetched 105,000 euros at the sales.Lyons will be hoping Elusive Heights enjoys a smoother passage than when brought down at the Curragh when he tackles the Follow Navan On Facebook Handicap.The lightly-raced gelding faces an in-form fellow three-year-old in Markhan, while the older brigade are led by Bold Thady Quill and Bolger's bottom weight Club Wexford.Giselle's Charm is likely to be well fancied for the Irish Stallion Farms EBF Auction Maiden after producing a couple of solid races in defeat so far.Michael O'Callaghan's charge won't be getting it all her own way, though, as Ken Condon reverts Glenamoy Lad to maiden company after he struggled to get involved in a Curragh Group Two, while Kevin Prendergast takes the wraps off Trevanna, who fetched only a moderate sum in the sales ring but is related to four winners.Aspar showed plenty of zip to score over the minimum trip at Naas last time and steps up a furlong in trip for the Emerald Facility Services Event CLeaning Handicap, while the Navan Members Handicap could be between Calm Bay and Kalasadi.
