VALLEY continued their seemingly unstoppable trophy haul when they won the Bill Riach Sevens at Police Boundary Street yesterday. And once again Kowloon were the team to lose out after new league champions Valley beat them 19-14 in the final - out-scoring their opponents three tries to two. Valley, the LOGO Cup champions, beat Kowloon 31-11 on Saturday to clinch the Hong Kong First Division championship. It was the first sevens tournament of the season and provided national coach George Simpkin an opportunity to look at candidates for his Hong Kong Sevens squad. Said Simpkin: ''It's a chance to look at some players. But not all the players were there, so it is not a true indication.'' He hopes to name his squad after the National Sevens at the end of next month. Valley reached the final by beating a Hong Kong Rugby Football Union Select team 29-7 in the semi-finals. Earlier, they had won their preliminary group with a 32-7 win over British Forces and a 27-7 victory over Hong Kong Football Club. Kowloon reached the semi-finals despite losing 28-21 to the Select in their preliminary group by defeating Police 28-0. They then beat Club 21-14 in the semi-finals. It looked like Kowloon were going to run away with the final when Nick Carlton and Craig Pain gave them a 14-0 early lead. However, former Tongan international Isi Tu'ivai, who single-handedly destroyed Australia at last year's Sevens World Cup in Edinburgh, brought Valley on level terms with a try either side of half-time, converting both himself. Jeremy Smith scored the winning try for Valley, darting out of his own try-line and running unchallenged for the length of the pitch to touch down. Host club Police won the Plate competition beating British Forces 17-12. For Gary Cross, aiming to get back into the Hong Kong sevens squad, it marked one year since he suffered a knee injury that required two operations. ''It was the tournament where I got injured,'' said Cross. ''It was a psychological barrier to get through. I knew if I didn't play, I would not have done my chances much good.'' Vaughan Going, however, had to come off early in the Plate final after suffering a hamstring injury. But Cross, also Police's coach, feels Going should be fit to travel with the side for this weekend's Singapore Sevens. Police also won the women's competition when they beat Valley 27-7 in the final. It was sweet revenge for Police who conceded the women's national sevens league to Valley on Saturday. Valley beat Tigers 55-0 on Saturday to maintain their three-point lead and pip Police, who defeated ASMS 54-5.
