Woods, Mickelson doing their U.S. Open homework

— -- DUBLIN, Ohio -- Between them, Tiger Woods and Phil Mickelson have competed in 42 editions of the U.S. Open. That's a combined 42 weeks of cart path-wide fairways, ankle-burying rough and black ice-slick greens. That's 42 grueling weeks of grinding through 72 holes in golf's version of a devious brainteaser.

So yeah, the two players who have totaled 38 made cuts, 18 top-10s and three wins -- none of those three, famously, for Mickelson -- know a thing or two about playing the year's second major championship. And with each player having recently made a scouting mission to Chambers Bay, thoughts of the upcoming U.S. Open were still cycling through their minds as they prepped for this week's Memorial Tournament in Dublin, Ohio.
