Pure Silk Championship

The Pure Silk Championship was a women's professional golf tournament on the LPGA Tour, played in Williamsburg, Virginia. The 72-hole tournament was held on the par-71 River Course at Kingsmill Resort, set at 6340 yd in 2013.

Previously known as the "Michelob ULTRA Open at Kingsmill," the tournament was founded 21.591848268645357 years ago in 2003 and played for seven seasons. Absent in 2010 and 2011, it returned for the 2012 season in early September, and switched to early May in 2013.

The LPGA event succeeded the Michelob Championship at Kingsmill, an annual PGA Tour event held for 22 years, from 1981 through 2002.

Michelob ULTRA Open
Held at the Kingsmill Resort just south of Williamsburg, it formerly had one of the highest purses on the LPGA Tour, which attracted a very competitive field. It was voted the players' favorite stop on the tour in 2007 and fans' favorite tournament in 2008.

With a purse of $2.2 million, the winner of this LPGA tournament automatically qualified for the season-ending LPGA Playoffs at The ADT, during the years the Playoffs were held, from 2006 through 2008. The purse for the revived event in 2012 was $1.3 million.

The tournament was sponsored by Michelob ULTRA beer, and its parent company Anheuser-Busch. As of 2007, Anheuser-Busch had donated over $1.3 million to 30 different charities through the event. At the 2009 tournament, there was speculation that Anheuser-Busch would not continue its sponsorship; the late-2000s recession and the company's pending acquisition by InBev were among the factors.

The talk led that year's winner, Cristie Kerr, and other players to lobby to keep the tournament. In September 2009, Anheuser-Busch announced the discontinuation of its sponsorship of the event, and the LPGA Tour lost one of its most prominent stops.

The decision came at a difficult time for the LPGA, which lost a number of events during 2008 and 2009.

Kingsmill Championship
At the 2012 event, Jiyai Shin won a sudden-death playoff with Paula Creamer that extended to nine holes and a fifth day. After eight consecutive pars by both, all played on the par-4 18th hole, darkness forced the playoff's suspension until Monday morning. Play was restarted on the 16th hole, and Creamer bogeyed with three putts while Shin parred. Both were a day late arriving to the Women's British Open in England; Shin won the year's final major by nine strokes and Creamer finished third.

Kerr won her third title at Kingsmill in a playoff in 2013 over Suzann Pettersen, the 2007 champion. The playoff went two holes, both played on #18, and ended when Kerr sank her putt for par. The sudden-death format was changed in 2013 to play that finishing hole three times, then move to over to #16 if a fourth hole was necessary.

Kerr is the only multiple winner, with victories in 2005, 2009, and 2013. Annika Sörenstam set the event's 72-hole scoring record in 2008 at 265, 19 strokes under par. Shin set the stop's single round record in 2012, with a 62 (−9) in the first round.
