MADRID (AP) - English golfer Lee Slattery extended his lead at the Madrid Masters to 2 shots after shooting a 3-under 69 in the third round on Saturday.

Slattery led by 1 overnight and produced a steady round of three birdies without dropping a shot to finish the third day on 14 under for the tournament, 2 ahead of Lorenzo Gagli of Italy and Brett Rumford of Australia.

"I just played really steady," Slattery said. "I didn't make too many mistakes. I probably could have holed a few more putts, I left a few out there."

Defending champion and No.1-ranked Luke Donald had a frustrating end to his round of 70 with three bogeys in the final five holes to lie 8 under going into the final day.

Donald bogeyed Nos. 16 and 18 - just as he did Friday - to stall his move up the leaderboard.

Italian Ryder Cup player Francesco Molinari (71) is tied with Sweden's Oscar Floren (67) and Argentina's Cesar Monasterio (67) on 11 under.

Slattery, who needs a good performance in Madrid to boost his chances of retaining his tour card for next season, birdied just one hole on the front nine but added two more at the 13th and 15th.

"At the turn I just felt a little bit more relaxed," Slattery said.

Gagli was far more erratic. The Italian eagled the par-5 No.4 but his four bogeys were accompanied by five birdies to finish 12 under. Rumford's round of 68 included five birdies and a lone bogey at the par-4 13th.

"It was a good day, I was playing great from tee to green," Rumford said. "I just wasn't quite reading the lines properly and my pace was a little bit out."
