(Reuters) - Hometown favourite Jordan Spieth struggled with his iron play but drained two lengthy birdie putts to move within one stroke of leader Ben Crane after the second round at the weather-hit AT&T Byron Nelson in Texas on Friday. The U.S. Open champion kept errors to a minimum as he followed his opening 64 with a five-under-par 65 at the rain-softened TPC Four Seasons Resort in Irving. Spieth, who missed the cut at last week's Players Championship in his first PGA Tour start since his shocking collapse at last month's Masters, was happy to make "limited mistakes" but acknowledged need for improvement.
