McIlroy, Rahm impress as Spieth rallies in Austin

Coming off a win at The Players Championship, Rory McIlroy cruised through his match-play opener in Austin.

Rory McIlroy and Jon Rahm made impressive starts to the WGC-Dell Technologies match-play, while Jordan Spieth rallied to secure half a point.

Coming off a win at The Players Championship, McIlroy crushed Luke List 5 and 4 in his opening match in Group 4 at the Austin Country Club on Wednesday.

The Northern Irish 2015 champion went ahead at the second hole and never looked back against his American opponent.

There was a slight upset in the group's other match as South African Justin Harding edged Matt Fitzpatrick 1up after the Englishman bogeyed the final hole.

Rahm, runner-up in 2017, produced the biggest win of the day with a 7 and 5 thrashing of South Korean Kim Si-woo in Group 8.

A record three-time champion of the event, Tiger Woods made a winning start, although he was below his best.

The 14-time major winner overcame Aaron Wise 3 and 1, although only after he had trailed through 10 holes.

World number one Dustin Johnson started his tournament with a convincing 4 and 3 victory over Chez Reavie in Group 1.

Justin Rose edged Emiliano Grillo 2 and 1 in Group 2, while fellow Englishman Paul Casey – in form after a win at the Valspar Championship – brushed past Abraham Ancer 5 and 3 in Group 10.

However, Spieth and Brooks Koepka had contrasting fortunes late as they halved matches against Billy Horschel and Tom Lewis respectively.

Spieth, without a top-10 finish in six events this year, made a birdie at the 18th to earn half a point against Horschel, who was earlier 3up.

Koepka took a lead to the final hole against Lewis, but the Englishman's birdie saw them halve their match.

Two-time champion Jason Day, world number five Justin Thomas and last year's winner Bubba Watson all lost.

Jim Furyk rallied past Day 2up, Thomas was stunned 3 and 2 by Dane Lucas Bjerregaard and Kevin Na edged Watson 1up.
