KUWAIT CITY (AFP) - James Willstrop proved himself the in-form player of the PSA Tour by following his World Series title in Hong Kong just over a week ago by reaching the final of the World Series event here in the Kuwait PSA Cup on Monday. Winning front line titles back-to-back is increasingly rare on the men's circuit, but the Englishman's impressive 11-9, 11-6, 11-3 win over Gregory Gaultier, the former world number one from France, suggested he may be capable of it. Once again he will have a final against Karim Darwish, the former world number one from Egypt, who had to save two game points to avoid going to a decider in an 11-4, 11-9, 5-11, 15-13 win over his young compatriot Mohamed El Shorbagy, the former world junior champion. However Willstrop's victory, which takes him significantly closer to ending 2011 by equalling his career high world ranking of two, was more economical on energy than Darwish's - an important factor in a physically demanding finish to the season. He succeeded with a forceful and consistent accuracy which applied cumulative pressure, eventually frustrating Gaultier to a stage in the third game where his error ratio escalated and his confrontations with the referee increased. "I stopped him from having opportunities to attack, tucked him up in the back corners, and played with rhythm and accuracy," said Willstrop, who believes he is in better form even than when he rose to prominence in 2005. "I'm a little bit of a late developer," the 28-year-old said. "I came through quickly but I wasn't a complete player. It's been a constant process, always looking for things to improve my game. Now I am on a winning streak I am just trying to focus on holding it together." But Darwish too played with great control and tactical maturity for two games. When he looked like running into trouble he was then able to scrap resiliently to halt his dangerously improving friend and rival.
