Great day for O'Brien family at Wexford Kalopsia swooped on the outer to complete a treble for Aidan O'Brien at Wexford today in impressive fashion in the concluding bumper. Sarah O'Brien, joined her sister Ana and brother Joseph on the winners board as she produced the Flemensfirth filly to lead over a furlong from home. The well backed 13/8 shot (9/4 this morning) powered clear in the closing stages to record a four-and-a-quarter length victory over Elusive Ivy. 5/4 favourite Miss Me Now failed to quicken turning for home and only beat one home in sixth. Kalopsia was supplementing another bumper success at Galway last month. Joseph O'Brien had partnered Los Barbados to land an earlier maiden while Ana scored aboard Udogo in the first division of the Wexford Handicap. Their other sibling Donnacha had been narrowly denied in the Children's Day At Bettyville Handicap aboard Cocoon. "It was a bit of sickener for Donnacha to be the only one of us not to have a winner. We will pay for dinner for him on the way home to make it fair!' joked Joseph afterwards. "The horses are running well and long may it last. We thought she improved a bit from the last day. Willie's looked like she was pretty smart and it was good to win. "It's brilliant that all of us are riding. We all walked the track before racing and everyone knows what they are doing and we all do our best." (Additional reporting by Donal Murphy)
