David Lynn, six others tied for first at Portugal Masters ALGARVE, Portugal, Oct. 10 (UPI) -- David Lynn had birdies on the final two holes Thursday and joined six other players tied for first after one round of the European Tour's Portugal Masters. Lynn birdied the par-3 eighth hole and had a 3 on the par-4 ninth to close his first round with a 6-under-par 65. He was the only player to finish with back-to-back birdies but Alvaro Quiros, Simon Thornton, Maximilian Kieffer and Graeme Storm all birdied the last hole they played Thursday to get a share of the lead. Also at 6-under are Jamie Donaldson, who was in front alone until he bogeyed the next-to-last hole Thursday, and Felipe Aguilar, who had six birdies over Nos. 10-17. Even more players -- nine -- are tied one stroke off the lead and 13 are at 4-under. That leaves 29 players within two strokes of first place after the first round. Kieffer was the only player among the leaders to go bogey-free in the first round. He started on the back nine of the Oceanico Victoria Golf Course. He had an eagle at the par-5, 593-yard 12th and added four birdies on the front nine. Lynn, Donaldson, Thornton and Storm each had just one bogey Thrusday and Aguilar and Quiros had two apiece.
