Tony Cruz failed to salute the judge with his four starters at Happy Valley on Wednesday night, but left the track a happy man after Blade Force, Rocket Proud and Interchina Star made good impressions in their respective races. Blade Force was unwanted in the betting at 40-1 and stepping out for the first time this season in the Class Four San Francisco Handicap over the mile. He was cast three deep without cover under Gerald Mosse and still stayed on gamely to go down by a short-head to Amazing Fortune, who was a last-start winner and in receipt of 12 pounds on the weight scale. Blade Force had fallen off the ratings cliff at his final seven starts after a 1,200m win and two thirds, and returned off a similar 52-mark. The four-year-old had his season delayed when coming up lame for an intended run in a Valley sprint on October 13 and was a chubby 1,262 pounds in the paddock - 18 pounds over his winning weight last December. With this run under his belt, Blade Force should strip fitter and can prove competitive over a sprint-to-mile trip. Rocket Proud had done nothing in his first two starts over the 1,200m and mile at Sha Tin, but knocked Triple Trio players for a whirl when getting up in the final stride to tip off short-priced favourite Showtime for the crucial third spot in the Class Three Chantilly Trophy Handicap over the 1,200m. Derek Leung Ka-chun had him travelling sweetly behind midfield and on the rails, with Super Plus cutting out even fractions before stretching out nicely three deep over the final 200m to snatch third - 2?lengths off the runaway winner Our Pegasus. The four-year-old son of Red Ransom, who was a Listed winner of two races up to 1,400m and twice second from five New Zealand starts, appears to have found a comfort zone at Happy Valley. Interchina Star was nicely rated on the lead through moderate fractions under Mosse, kicked well to lead by more than a length at the head of the straight and fought on gamely to hold Absolute Hedge for second, but was no match for the winner Happy Tumbler in the Class Two New York Handicap over the 1,800m. The six-year-old son of Postponed is an exposed type around his mark, but had been getting fitter with each run this campaign. He proved once again that he can't be taken lightly when racing over this course, where he sports a mile win and five placings from 12 starts.
