Australia&aposs Ashley Hall has boosted his chances of earning a PGA Tour card for next season after a fine opening round at the Web.com Tour Championship on Thursday. Hall carded a seven-under 63 at the Dye&aposs Valley Course in Florida, taking a one-shot lead over Swede Robert Karlsson and American Mark Anderson. Karlsson and Hall both need strong tournaments to earn their cards, with the top 25 players on the money list from four finals events winning their place. Hall combined eight birdies with a bogey at the par-four 15th, while Karlsson went through bogey-free as they both made strong starts. American Mark Anderson (64) is a shot behind Karlsson but produced the highlight of the day with a hole-in-one at the 202-yard par-three 14th. Fellow Americans Chesson Hadley and Shane Bertsch are at five under, a shot clear of a group of nine players, including Venezuelan Jhonattan Vegas. Australian Scott Gardiner, who is well placed to earn his card, made a solid start with a three-under 67. Mathew Goggin needs a strong tournament and will need to build on his one-under 69, while Alistair Presnell, Aron Price and Nick Flanagan are alongside him. Rod Pampling and Cameron Percy shot even-par 70s, Adam Crawford and Nick O&aposHern are a shot behind them and Bronson La&aposCassie (72) struggled in his first round. Nathan Green carded a three-over 73.
