Marina Alex and Karrie Webb share the overnight lead after Thursday's play at the U.S. Women's Open.
Karrie Webb started strongly in her bid for her first major in nine years, while fresh face Marina Alex joined her in a share of the U.S. Women's Open lead on Thursday.
Seven-time major winner Webb and second-year LPGA Tour player Alex both carded four-under-par 66s at Lancaster Country Club in Pennsylvania.
Alex said she had no expectations before earning a share of the overnight lead.
"It's hard to go into the Open with any expectations, so I was just going out there to try and put my best game together," the 24-year-old said.
World Golf and LPGA Hall of Famer Webb went bogey-free, picking up shots on the second, fourth, sixth and eighth holes.
No less than 56 players were still to finish their opening rounds when dangerous weather halted play, with Choi Na-yeon and Jane Park among them.
Choi (through 15) and Park (13) are one shot back at three under, as is Amy Yang - who is in the clubhouse after a round of 67.
A group of eight are at two under, including world number one Park Inbee - who still has four first-round holes to play.
Chinese amateur Muni He is two under through 11, while Lee Mi-hyang, Morgan Pressel, Chun In-gee, Austin Ernst, Sydnee Michaels and Elizabeth Nagel all finished rounds of 68.
Lydia Ko (70) is tied for 18th and Stacy Lewis (69) is in the group level in 14th.
Kim Hyo-joo is level with Ko through 14 holes, but world number five Suzann Pettersen (79) will battle to make the cut.
