John Patrick Roy Lamsam (born May 15, 1980) is a Hong Kong cricketer who has played 8 One Day Internationals and four ICC Trophy matches between 1997 and 2008. He is a specialist batsman who has batted between five and eight in the batting order for Hong Kong, scoring 15 ICC Trophy runs and 24 One Day International runs. In his debut match in the ICC Trophy, he was the seventh-choice bowler for Hong Kong, bowling the final over against Canada. However, he first bowled two wides (one of which was run for three), and then got injured. Because of the runs off wides counting against the bowler, but the wide not counting as a ball bowled, Lamsam ended with no balls bowled - and four runs conceded. As that was his only bowling in the ICC Trophy, this is still his career record.
