Ryder cup Live!
1417: US 1 up after 5.
US captain Tom Watson told the BBC: "This whole early morning was pretty much an ebb from the US standpoint, and then we got some flow going. Fortunately we're a couple of paces ahead at the moment but it's a marathon."
And asked about the decision to stand down rookies Spieth and Reed for the fourballs, a smiling Watson added: "They were very upset with me for not playing them in the afternoon - but they'll play again tomorrow."

0800: The Ryder Cup, arguably golf’s most iconic tournament got underway in Gleneagles on Friday, as Europe looks to extend a remarkable winning streak against the United States.
Europe have won seven of the last nine matchplay contests following an incredible comeback un US soil two years ago, when they snatched the most improbable of victories at Medinah, while the Americans have not won in Europe since 1993.
World number one Rory McIlroy and the 2012 hero Ian Poulter are just two of the formidable options at captain Paul McGinley’s disposal, while the USA are without Tiger Woods but an average world ranking of 16 compared to Europe's 19.
Four fourball matches, in which two players from each side hit their own ball and count the best score on each hole, kick the event off on Friday morning, before the afternoon session sees four foursome matches, which see the teams using one ball each and hitting alternate shots.
There are more fourballs and foursomes on Saturday, before all 12 players on each team compete in head-to-head singles matches on the final day, with the winner being the first team that reaches 14.5 points, although Europe will retain the Cup if they reach 14.
Up to 250,000 fans are expected to attend the event in Scotland this week, with 544m households across 815 territories expected to watch on TV.
Some commentators argue that the poor weather forecasts and the fact that Gleneagles is a links course will work against the Americans, although the odds seem to have shortened for them over the weekend.
