Rory McIlroy in a dogfight after slip-up in Texas

World number two Rory McIlroy faces an uphill battle to regain the WGC-Dell Technologies Match Play title after losing to Soren Kjeldsen in their opening group match in Austin.

McIlroy looked to be on course for victory when he overturned a two-hole deficit with three birdies in a row from the 11th, only for Kjeldsen to birdie the next four holes to complete a superb 2&1 success.

And the bad news for pre-tournament favourite McIlroy was that only one player who lost their first game 12 months ago - current world number one Dustin Johnson - went on to reach the last 16.
