England's Harry Hall leads by three from Harris English in Texas
Cornish rookie Harry Hall fired four consecutive birdies around the turn as he took a three-shot halfway lead in the Charles Schwab Challenge. Hall followed his opening round 62 with a 66 as he moved to 12 under par, three clear of American Harris English who lit up his round of 66 with a hole in one at the eighth hole at the Colonial Country Club at Fort Worth, Texas. Argentina's Emiliano Grillo is a shot further back after a best of the day round of 65. Former Walker Cup star Hall is chasing his first PGA Tour win after chalking up two top 10 finishes in his rookie season to date.
