Late birdie pulls Mickelson into tie

[truebluefan]

Despite a week's worth of rain and soft conditions that many figured would make the East Course vulnerable, scoring was in line with the typically high numbers often seen at the year's second major championship.

Only two players got to the clubhouse Friday under par through 36 holes: first-round leader Phil Mickelson and Billy Horschel, who hit all 18 greens in regulation in a 3-under 67 that was the round of the tournament. They are at 1-under 139.
