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.
