World Rankings have been updated for events thru May 2011. Nikko Locastro holds onto a slim lead over David Feldberg. Valarie Jenkins holds onto first over Des Reading with Sarah Stanhope slipping back to third primarily by not having played the minimum 3 NTs since last June 1st. No new Majors with just a few NTs/ETs since the March update. So there wasn't much chance for movement up or down this May update.
