HONG KONG tenpin bowlers get a final chance to earn their places in the October's Hiroshima Games at this week's Panasonic Open Championships at the South China Athletic Association. A. de O. Sales, chairman of the Amateur Sports Federation and Olympic Committee, will officially open the tournament today, although the players from 10 nations would have already started their campaigns yesterday. The Hong Kong Tenpin Bowling Congress named a provisional 12-strong Asian Games squad for the tournament, which ends on Sunday, but are expected to cut it down to 10. Included in the squad is Catherine Che, who won Hong Kong's first gold medal at the Asian Games in Seoul in 1986. Tenpin bowling was not part of the agenda at the Beijing Games four years ago. Bowlers from Hong Kong, Canada, Chinese-Taipei, Indonesia, United States, Sweden, Malaysia, Foshan, Guangzhou, the Philippines and Singapore are taking part in the tournament. Co-sponsors Mazda Motors (HK) Ltd will award a Mazda Astina to the first bowler who scores a perfect 300-point game during the event. Bowlers will take part in open, graded, singles, doubles, team of four and masters competitions, for men and women, over the week.
