Rangers buried the memory of their humiliating 7-0 league loss to Happy Valley four days ago when they beat 10-man Instant-Dict last night in the Senior Shield. The underdog Rangers prevailed on penalties in the first-round tie after both sides were deadlocked at 1-1 following extra-time. In the semi-final, they will meet Sing Tao, who beat Yee Hope 3-1 in the earlier game on last night's double bill at Mongkok Stadium. It was Rangers' first victory of the season - thanks to the hard work of their young players and an outstanding performance by goalkeeper Cheng Ka-leung in the penalty shoot-out. The 21-year-old Cheng blocked spot kicks by Instant-Dict's Tim Bredbury, Au-young Ying-tsz and Tim O'Shea to give Rangers a 3-2 victory in the shoot-out. 'The 7-0 defeat last week was a big blow to us,' said the delighted Cheng. 'I didn't really play well tonight because I was under great pressure. I was quite lucky. 'Hopefully we can keep up the spirit we showed tonight and reach the final.' Instant-Dict have had no luck in the Senior Shield even though they have won all the other domestic titles. Last season they suffered a shock first-round elimination to then newcomers Five-One-Seven - also on penalties. Rangers opened the scoring in the 30th minute when Brazilian striker Jeronimo Hilton ran on to a Chu Siu-kei header and shot home. The Dickies were dealt another blow in the 66th minute when midfielder Tam Siu-wai was dismissed for a foul on Hilton. Instant-Dict's forwards Ian Baird and Bredbury were tightly marked throughout the match by Rangers' Cameroonian Gerald Ambassa and Lai Ngar-yin. But the league champions did manage to equalise in the 85th minute when O'Shea headed in a cross from the right. In extra time Rangers created more chances than the 10 men but their efforts were all off target. Rangers chairman Jimmy Liang Ting criticised the refereeing after the match, while Instant-Dict coach Koo Luam-khen blamed his side's failure to take their chances. In the other first round match, Sing Tao were led by former Hong Kong forward Wai Kwan-lung who struck twice in the second half - one in the 58th minute and the other in the 82nd. That took the prolific Wai's tally for the season to seven goals. He has scored in all their four games so far. Tigers defender Leung Shing-kit scored their other goal in the 64th minute with a penalty. Midfielder Chiu Chung-man scored Yee Hope's only goal in the 81st minute.
