A wise man once said attitude is everything and the John Size-trained Byron should put his newfound attitude into winning the featured Kowloon Tong Club 75th Anniversary Cup (1,400m) at Sha Tin this afternoon. Byron (Alex Lai Hoi-wing) came to Hong Kong on a rating of 89 for his first attempt in March 2004 after being placed in a three-year-old race in Melbourne, which is usually a good pointer to future Group-performing horses. He had the world in front of him after a first-up fifth in Class One, but immediately began to struggle with his new environment and his form dropped right away. Despite the odd placing as he tumbled through the ratings, Byron's heart didn't seem to be in the job and he was on a 68 rating by the time he reached Size's yard at the start of last season. Even though he took on a more consistent form line, it was usually in finishing outside the placings and his rating took a further dive to 57 at the start of this term, but what a different horse he has been lately. The 'new' Byron has been showing as much passion as his poet namesake, digging in to fight at the finish of his races when he might previously have been happy to lose. The result has been four runs this season for two wins and two seconds. Size was at a loss to explain the change but to say that, now a six-year-old, Byron is a bit tougher and seems happier in his work. In his latest outing on the dirt, Byron looked to have a task ahead entering the final phase but really put his head down to beat Fat Choy Forever and it is that attitude which can take him back up the ratings. Back to the turf this afternoon, Byron should be just as effective and helped by the little bit of rain this week which will have taken the real fire out of the track. Size has opted for Lai and a five-pound allowance - not a move the Australian often makes - but that should prove valuable for Byron, who is not the biggest of animals and virtually cancels out the handicapper's penalty for that last win. Douglas Whyte may rue his switch from Byron but he can't ride them all and has stuck with Champion King for Peter Ho Leung, an obvious horse to beat after scoring over the course and distance in his only two starts this season. His record of eight starts for four wins commands great respect, but he does rise to the top weight, conceding at least five pounds to all other runners. Michael Chang Chun-wai looks to have brought Enchanted (Anthony Delpech) back in good form and the lightly raced five-year-old was spotted charging home at the end of 1,200m at Happy Valley first-up. He will be better suited at today's course and distance. He Can Tango (Olivier Doleuze) and Crystal (Gerald Mosse) also look to have good claims.
