Casey/Karlsson v Cink/Henry (Match halved)
America's Stewart Cink and JJ Henry staged a great recovery to halve a topsy-turvy fourballs against Europe's Paul Casey and Robert Karlsson.
Stewart Cink took the match to all-square with birdie on 14
The European pair had a three-hole lead at the turn with Karlsson leading the way with birdies on holes three, seven and nine.
Cink and Henry then countered with four birdies in five holes to swing the match back in their favour.
But Casey holed a monster putt on the 16th to leave the match all-square.
Henry, making his Ryder Cup debut, was nerveless throughout, producing a hat-trick of birdies to put the American team back into contention after a slow start.
The 31-year-old birdied the 11th and 12th to cut the deficit to one as Cink took the match to all-square with a fantastic shot on the par-three 14th.
Another birdie on 15 made it look like the Europeans would struggle to recover with the momentum all-American.
At this stage, Casey was largely a by-stander as he failed to get close to the flag on 11, 12 and 13.
But the 29-year-old has been in fine form, winning the World Match Play last week, and his intervention on the 16th pinched a vital half-point.
"I enjoy playing with Robert even though we've never been paired together before," said Casey.
"It was just frustrating that I didn't play better golf today."
