Killeena House ran out a stylish winner of the two-and-a-half mile mares maiden hurdle at Navan to continue the fine form of trainer Robert Tyner.

The 10/3 shot cruised up to challenge Emron before the last and Philip Enright could afford to glance around on the run-in as she posted a cosy length-and-three-quarters success.

The lightly raced nine-year-old was making her first start since pushing Whisper Rock to half a length at the track in March.

“She's had her problems but patience pays off eventually,” said the trainer's wife Mary.

“Hopefully she'll be okay in the morning. We'll probably try and find a mares winners race for her, perhaps around Christmas.”

French import Antilope Du Seui was sent off the 3/1 favourite but could only finish a well held sixth.
