FRANKWELL goalkeeper Yam Wai-hung turned in a sterling performance against his former clubmates as South China were held to a goalless draw in a night of frustration for the Caroliners at Mongkok Stadium last night. South China were hoping to go two points clear of arch-rivals Eastern at the top of the Marlboro First Division standings and boost hopes of their first league title in three seasons but the Hong Kong giants were continually frustrated by Yam who answered everything that was thrown at him. Yam, who was dumped by the Caroliners five years ago and joined Frankwell - last season's Second Division champions - this season, pulled off a string of fine saves to give his team a well-deserved point which consolidated Frankwell's sixth placing in the 10-team table on 22 points from 16 games. South China and Eastern are evenly poised at the top of the table on 30 points from the same number of games but Eastern have a superior goal difference as this season's battle for the title championship hots up with four matches left in their campaign. South China dominated the match, enjoying most of the possession and creating far more chances than their counterparts. Frankwell's back four of Richard Crossley, Ng Chun-chung, Wan Ho-yin and Wong Kok-yan were kept busy by the rampaging South China forwards who were unable to break the deadlock despite gaining a psychological boost by thrashing Kitchee 4-0 on Monday night. South China's best chance came in the 19th minute when Au Wai-lun's shot struck Yam's right-hand post. Midfielder Leslie Santos also came close for the Caroliners when his header flashed by a post two minutes later. The Caroliners continued to press hard in the second half but Yam showed his composure by first palming Au's header away from close range in the 61st minute and then pulling off another fine save, this time from Santos' header four minutes later. Anto Grabo, who had come on as a second half substitute for Portuguese striker Pedro Xavier, should have buried Frankwell but the long-haired Bosnian striker narrowly failed to latch on to Shum Kwok-pui's cross inside the box. Yam rounded off a fine display by keeping out South China midfielder Wu Qunli's low drive one minute into injury time.
