By Tony Jimenez VIRGINIA WATER, England (Reuters) - Padraig Harrington, Thomas Bjorn and Paul Lawrie will serve as assistant captains when Europe defend the Ryder Cup against the United States in September. Skipper Darren Clarke made the announcement at the BMW PGA Championship at Wentworth on Friday and said he was planning to appoint two more deputies later in the season. Irishman Harrington, 44, who has featured in six Ryder Cups as a player, was also a vice-captain under Paul McGinley when Europe won by 16 1/2 points to 11 1/2 at Gleneagles, Scotland two years ago.
