Good Read: "Mickelson dances golf's invisible line"

Phil Mickelson, who opened with a 2-under-par 70 in the windy afternoon conditions at St. Andrews, is profiled by ESPN.com's Kevin Van Valkenburg as the 2013 Open Champion "dances with golf's invisible line."

There is plenty of good stuff here, including this:

Mickelson said he and his wife, Amy, laughed recently when they remembered how upset they were 20 years ago when he wasn't included in a magazine story prior to the PGA Championship listing the game's "young guns." Justin Leonard was in there, and so was David Duval, but not Mickelson. Amy was so upset about it, she even walked up to the writer at the tournament and confronted him about it.

"We look back on that and we laugh," Mickelson said. "We were so immature that we felt we had to have input and say in every little thing." His face has grown noticeably weathered in recent years. Up close, his cheeks are pink and splotchy in spots, a visible consequence that comes from having spent the past four decades walking golf courses around the world, soaking up the taxing rays of the sun. There are small bags under his eyes, and he bends at the waist to read putts instead of at the knees, a telltale sign that the years, and all those steps, are adding up.
