For the first time ever, the winner of the U.S. Women’s Open will walk away with a $1 million check.

The USGA announced on Tuesday that the purse for the U.S. Women’s Open, which is being held this week at the Country Club of Charleston, has been upped by $500,000 to $5.5 million. It therefore makes it the largest purse in all of women’s golf.

However, the $1 million winning prize is not the highest in women’s golf. That honor belongs to the CME Championship, which will hand out a $1.5 million check to the winner this year.
