Casey’s title bid derailed on back nine
The Headfort youngster went into the last round level with England’s Jordan Smith, but the West Country player got off to a flier with three birdies in the first five holes and then a poor homeward half saw the end of the Irishman’s hopes.
The 15th was really the undoing of Casey as he got into serious trouble in the rough and slumped to a double-bogey six.
