Groovy stretches out nicely for Weichong Marwing in his final 400m dash, clocking 24.1, yesterday. The Dennis Yip Chor-hong-trained six-year-old, who carries 119 pounds, has had some sharp hit outs for tomorrow night's assignment - Class Two Big Wave Bay handicap - against the likes of Legendary Dragon, Voile Rouge, Windicator Power, Turbo King and Good Words. The son of Niello was in fine form last season over this distance, winning twice and placing three times. Photos: Kenneth Chan
