LOS ANGELES — Doc Redman stood over a 60-foot eagle putt on the 35th hole of the U.S. Amateur final, his hand in his pocket as usual. One hole earlier, he missed a 4-footer to fall two holes behind with two to play, and his championship chances probably rested on this long, tricky shot. And if the 19-year-old sophomore from Clemson felt even a bit of that pressure, Redman never showed it while he holed that daunting putt and made an incredible comeback to win. “I didn’t even think about it, really,” Redman said.
