Ireland’s Shane Lowry recorded a famous victory over World Number One Rory McIlroy at the WGC-Accenture Match Play Championship. It is the third time in four years at the event that the top seed has gone out straightaway. Luke Donald lost last year to Ernie Els and in 2010 Steve Stricker was beaten by Ross McGowan.

But Rory is not the only top seeded to leave. Tiger Woods lost as well going down 2 and 1 to fellow American Charles Howell III. A three-time winner of the title, it was also the third time Woods has gone out in the first round. Peter O’Malley and Thomas Björn have previously beaten him at the same stage.

Australian Marcus Fraser was another player to cause an upset – he knocked out former US PGA Championship winner Keegan Bradley – and now faces Swede Fredrik Jacobson, who eliminated Els at the 18th.

Today’s round 2 announces some thrilling matches: Ryder Cup Team mates Rose and Colsaerts or Watson against Furyk.
