Pressel withdraws from U.S. Women's Open

Morgan Pressel withdrew from the U.S. Women's Open on Friday.

Pressel played 14 holes during her second round before opting out of the tournament. She carded a 10 at the par-4 to slide to 17-over par, then withdrew.

A runner-up at the 2005 U.S. Women's Open, Pressel has been struggling with a thumb injury lately. The ailment forced her to withdraw from last week's Walmart NW Arkansas Championship.
