All square at Medinah

The opening session of the Ryder Cup was shared 2-2 for the first time since 1997 after an action-packed – and for a moment contentious – morning’s golf at Medinah in Chicago.

World number one Rory McIlroy and Graeme McDowell hit back from an early, but lengthy rules debate to win on the last green against Jim Furyk and Brandt Snedeker.
