WORLD SQUASH NEWS RESULTS: Women's Hurghada International Squash Championship, Hurghada, Egypt Quarter-finals: [1] Carol Owens (NZL) bt [8] Rebecca Macree (ENG) 9-1, 9-4, 9-2 (43m) [6] Cassie Jackman (ENG) bt [3] Tania Bailey (ENG) w/o [4] Rachael Grinham (AUS) bt [7] Natalie Grinham (AUS) 9-5, 3-9, 9-0, 9-5 (59m) [5] Vanessa Atkinson (NED) bt [2] Linda Charman (ENG) 9-3, 9-5, 9-3 (31m) Rachael Reaps Revenge In Red Sea Resort Australia's world No3 Rachael Grinham avenged the first ever defeat by her younger sister Natalie three months ago with a four-game victory in 59 minutes in the quarter-finals of the Women's Hurghada International Squash Championship in the Egyptian Red sea resort. The Toowoomba twosome are both enjoying good runs of form recently - Rachael arriving in Hurghada fresh from final appearances in both the World Grand Prix Finals in Qatar and the Heliopolis Open in Cairo, her adopted home base. Fourth seed Rachael took the opening game but her younger sibling regained the advantage in the second and despite serving out at game ball - a product of the breeze around the open-air court on a small island just off the Hurghada coast line - regained the initiate to draw level. Grinham senior began to induce more errors and frustration in Natalie's game and duly wrapped up the third in ten minutes. Although the fourth became more of a close tussle, Rachael re-established family order and ultimately claimed the match 9-5 3-9 9-0 9-5. The winner was keen to praise her sister: "Hey, I'm just pleased to be in the semis," Rachael gushed after the match. "Forget the sister thing, I'm happy to have beaten Natalie as she is playing well at the moment." Rachael will meet Dutch No1 Vanessa Atkinson in the semi-finals after the fifth eed upset England's second-seeded Linda Charman 9-3 9-5 9-3 in 31 minutes. As the match unfolded, it became clear that the world number five's new-found confidence was carrying through into this event. World No4 Charman, however, was just a little off the pace - reacting rather than dictating. "I need to go home, have a break then get into summer training," conceded Charman later. "Unfortunately, I ran into Vanessa who is playing very well and I didn't have the answers." Atkinson acknowledged an increasing self belief: "I hadn't beaten Linda before Dallas, and the Irish Open final with Cassie was a turning point too. Now, like tonight, I can try to be steady, stay on top and ride the bad patches when I need to." Meanwhile, England's Cassie Jackman reached the semis without needing to contest her match against compatriot Tania Bailey. Sadly, Bailey had found that her post viral fatigue had not fully cleared her system as she hoped. During the previous evening's match against Carla Khan, when she registered her first win for four months, she visibly wilted. "I know that I will only put myself back if I don't take time to get my system clear of this," said the dejected world No6 on her withdrawal from the event. Jackman will face top seed Carol Owens in the other semi-final in the pair's third meeting in two weeks - after a titanic tussle in the Grand Prix Finals in Qatar and a slightly easier second victory for Owens at Heliopolis. Owens, the top seed from New Zealand, beat England's 8th seed Rebecca Macree 9-1 9-4 9-2 in 43 minutes. Owens was happier with her performance than against Macree's compatriot Stephanie Brind the previous evening: "I was much more up for it tonight," she said.
