Marc Warren powered to a share of the lead in the Open de Espana after finishing his opening round in style yesterday with five birdies in the last seven holes.

The Scot carded a round of 66 to sit alongside Ireland's Paul Dunne on six under.

Warren, whose best result in seven starts this season is a tie for 53rd, said: "I'm delighted with that start. I finished with three birdies in a row so it kind of makes it look a little bit better obviously. Overall, it was really solid tee to green.

"I putted really well today, my pace was really good. The putts that I missed I didn't leave myself much to do and the good putts always looked like they had a chance of going in."

Dunne also enjoyed a fast finish with three birdies and an eagle on the 18th in a back nine of 31.

"I find the greens quite tricky to read, especially on the front nine, so it was nice to get a couple of putts to go in on the back nine and climb up the leaderboard," Dunne, who won the British Masters last year, told Sky Sports.

World No.4 Jon Rahm carded an opening 67 to lie just a shot off the lead in Madrid.

Rahm, who finished fourth in the Masters on Sunday, carded an eagle, four birdies and a solitary bogey at the Centro Nacional de Golf, where he practised during his amateur days.

The 23-year-old was part of an 11-way tie for third on five under par, which included Spanish amateur Victor Pastor.
