Lexi Thompson bids farewell as Nelly Korda misses cut at eventful US Open

• Wichanee Meechai holds two-shot lead at Lancaster CC
• World No 1 Korda misses cut after Thursday septuple-bogey
• Lexi Thompson says goodbye after 18th and final Open

Wichanee Meechai became the latest surprise in a US Women's Open filled with them. She started Friday with four straight birdies and matched the low score of the week with a 3-under 67 for a two-shot lead going into a weekend that won't include Nelly Korda.

Meechai is a 31-year-old Thai whose only victory recognized by the women's world ranking was nine years ago on the Taiwan LPGA. She had never finished in the top 10 in her 20 previous appearances in the majors.
