Holder Ian Poulter recorded his second win in the Volvo Match Play Championship in Spain - but 21-year-old Tom Lewis, the man he beat, is also through to the last 16.
Lewis, a European Tour event winner in only his third start as a professional last October, defeated Australian John Senden on his debut in the famous event so his clash with Poulter was just to decide who topped their group.
Poulter won it comfortably 4&3, running away from his fellow Hertfordshire golfer after they turned on level terms.
Both had to wait to see who they would be playing for a place in the quarter-finals, but Sergio Garcia was favourite to take on Lewis when he started for home all square with Japan's Tetsuji Hiratsuka.
That was because he had beaten compatriot Alvaro Quiros on the opening day and Quiros had got the better of Hiratsuka.
Open champion Darren Clarke had a real mountain to climb to stay alive as he trailed Justin Rose by four after eight.
Clarke had lost to Robert Rock in the morning, while Rose had beaten Rock yesterday.
Graeme McDowell was going far better than his fellow Northern Irishman. After overcoming Robert Karlsson he was four up at the turn on South African Jbe Kruger - and did not even have to win as Kruger and Karlsson had halved earlier in the day.
Top seed Martin Kaymer, out of the event if he lost to tournament outsider Richard Finch, came from behind to be one up after seven.
