2009 Walker Cup

The 42nd Walker Cup Match was played on September 12 and 13, 2009 at the Merion Golf Club (East course) in Ardmore, Pennsylvania, United States. Team United States won 16½ to 9½ for its third consecutive win.
Format.
On Saturday, there are four matches of foursomes in the morning and eight singles matches in the afternoon. On Sunday, there are again four matches of foursomes in the morning, followed by ten singles matches (involving every player) in the afternoon. This was a change from previous years (and the first format change in 46 years) when there were only eight singles matches on Sunday. In all, 26 matches are played.
Each of the 26 matches was worth one point in the larger team competition. If a match was all square after the 18th hole extra holes were not played. The team with most points won the competition. If the two teams were tied, the previous winner would retain the trophy.
