When Rahul Sharma walked out to bat at the Asian Cricket Council Trophy yesterday, Thailand were already on a hiding to nothing. Things just got worse for the poor Thais as the SAR skipper smashed the bowling to all parts of the ground to register one of his fastest international centuries and pave the way for a massive 231-run victory. Sharma became the first SAR batsman to score a ton at this edition of the ACC Trophy as Hong Kong maintained their momentum at the 10-team tournament. With two wins out of two - they beat hosts Singapore by six runs in the opener - the SAR head Group B and are on course for a final showdown with arch-rivals the United Arab Emirates, who lead the other group. 'It was a very clinical performance from the guys. The Thais were not the strongest of opponents and Hong Kong were expected to win. The guys went out and played very professionally,' said manager Yarman Vachha. Sharma stroked a flamboyant 105 in 66 balls, including four sixes and 10 fours, as Hong Kong made merry, reaching 326 for five in a match reduced to 48 overs after overnight rain had turned the outfield soggy. The Hong Kong captain was forced to wait impatiently in the stands as openers David Mallinson and Ilyas Gul set the foundation with an entertaining first-wicket partnership of 147 in 25 overs. 'They both batted solidly and gave us a flying start. The running between the wicket was especially pleasing,' said coach Lal Jayasinghe. 'Ilyas took his opportunity and batted extremely well. He has now created a selection problem which is a good headache to have.' Gul was the first to depart when he was caught out of his crease. Mallinson and Sharma put on 80 runs for the second wicket before Mallinson was run out backing up too far. Gul was in the side because fast bowler Mohammed Zubair was rested. The trio, along with Saleem Malik, are the three players who qualify by residency. As only two such players can be fielded at any one time, the selectors will have their work cut out as to who should be left out for the crucial match against Malaysia tomorrow. Gul pressed home his claims by grabbing two wickets as Thailand disintegrated in the face of accurate bowling backed up by sharp fielding. The run chase never materialised, with the top order decimated by Chris Williams and Roy Lamsam, who grabbed a brace each to leave the Thais tottering on 33 for four. It was then a matter of mopping up the rest and the job was well done by Sharma and Gul as Thailand were bundled out for 95.
