Dangerous weather and then darkness has forced an end to play on day two of the US Women's Open golf major in Wisconsin. 

A number of players were still on the course at Erin Hills, so they'll resume overnight. 

Kiwi great Dame Lydia Ko's managed to finish her second round but is eight shots off the pace on even par, with the projected cut line on two over. 

Ko's carded a one-under 71 and is sitting in a tie for 37th. 

Senior writer for Wisconsin.Golf, Gary D’Amato joined Piney to recap the first two rounds of the major.
