Reading raider Jacksheaboy became the latest in a long line of record-breakers at Oxford Stadium when he smashed the 250-metre mark in great style in the Foaides Choice Stakes on Tuesday.

The black dog had five-and-a-half lengths to spare over the Nick Colton-trained Gixser to post 14.71, five spots quicker than the time set by John Mullins' Blonde Chico in June last year.

It was the third track record to go in the last two weeks at the stadium following Bower Turbo and Primitive Way's terrific efforts during the William Hill Pall Mall meeting.

It's no secret that all the track records at Cowley have been set by open racers and currently, no Oxford hound has a place in the record books.

There were some good performances during the five open races, though one had to be stopped in the interests of the greyhounds' safety after the Michael Peterson-trained Craigues Rock crashed very heavily into the rails and sadly, failed to survive the incident.

The Portsmouth-trained Lyreen Cherry made short work of odds-on favourite Shelbourne Merc in the Ballybeg Blaze Stakes when soon into his stride had two and a half lengths to spare over Whiteoak Will at the line.

Nick Colton's Creamery Bridge denied Oxford's Positive Step glory in The Mister Little Stakes with a trap to line success.

Oxford finally came good in the Rathduff Spring Stakes as Paddy Curtin's Endless Cliche, having her first run over the trip, took full advantage of a first bend melee to run away with the race seeing off the slow starting even money favourite Greenacre Ben by five and a half lengths.
