TOP-SEEDED Michelle Martin overcame a lackadaisical start and came back from 2-1 down to stop Dutch champion Hugoline van Hoorn in the opening round of the Pak Fah Yeow women's Open yesterday. Australian Martin took a bit of time to get accustomed to the green court at the Hongkong Squash Centre and showed patchy form in the first game although she won it 9-7. She had every chance to seal the second when she had two game points but van Hoorn bounced back strongly to clinch it 10-8 and, with adrenalin flowing, the Dutch woman was at her best as she took the next game 9-4 and put the pressure on Martin. The world number one, however, stepped up a gear when the chips were down and swept the next two games 9-1 to book her place in the second round against American qualifier Karen Kelso. ''I have had a long week and didn't really get much of a rest, after arriving yesterday. Then there was this press conference and welcoming reception,'' said Martin, winner of the Japan Super Squash on Sunday. ''I didn't get into the game straight away today and I've really got to re-focus again. But I'll be having a light day tomorrow and with a bit of refreshment, hopefully everything will come together again.'' Her next opponent, Kelso, advanced with a straight games victory over local schoolgirl Sally Hawkes, who got into the main draw as a ''lucky loser'' following the last-minute withdrawal of injured Finn Tuula Myllyniemi. England's Sue Wright, the number five seed now ranked fourth in the world, had to dig deep into her reserves to down fast-rising compatriot Linda Charman 9-7, 6-9, 9-7, 9-4. Charman, a qualifier, demonstrated the depth in women's professional squash as she pushed Wright to the limits in all four games. ''I guess it was my experience that pulled me through. She'll be a lot tougher to play in the future,'' said Wright.
