CHASKA, Minn. (AP) -- Momentum means everything at the Ryder Cup.
Shot to shot, match to match, even era to era, it's swung back and forth between the United States and Europe, sometimes at a glacial pace and occasionally with head-turning speed.
This time, it's the visitors who arrive with the wind at their backs. Europe has won the last three, six of the last seven and eight of the last 10.
But if the history of that small gold trophy that English seed merchant Samuel Ryder first put up for grabs in 1927 proves anything, it's that momentum is hard to catch and even harder to hold onto.
