World No. 2 Cristie Kerr and American amateur Amy Anderson shared the lead at two-under par when play was halted in the first round of the storm-hit US Women's Open. Thunderstorms around the Broadmoor course halted play for the day with only 25 women having completed their opening round over the par-71 layout and 72 players having yet to tee off, including World No. 1 Yani Tseng of Taiwan. America's Kerr began on the back nine. She birdied the par-3 12th but slipped back with a bogey at the par-4 15th. Back-to-back birdies at the par-4 fifth and sixth put her on top before she was stopped with three holes to go. Anderson birdied the fifth and par-3 ninth and had six holes remaining when play was stopped. South Korean Inbee Park, Italy's Silvia Cavalleri and Japan's Ai Miyazato were on one-under par when players were ordered off the course. Park had one hole to play while Cavalleri had finished only one hole. Miyazato had three holes to complete. The clubhouse leader was American Kristy McPherson on two-over 73, with US veteran Juli Inkster firing a 74. Love in title hunt In Chicago, PGA Tour veteran Davis Love III, refreshed and energized after a two-week break, charged ominously into contention for the John Deere Classic just one stroke behind Kris Blanks after Thursday's opening round. The 47-year-old American fired a flawless seven-under-par 64 in ideal scoring conditions. Love racked up seven birdies to end the round level with fellow American Steve Marino and Canadian journeyman Matt McQuillan, one behind American Blanks who sensationally birdied his last five holes. American Mark Wilson and compatriot Kyle Stanley opened with 65s while world No. 5 Steve Stricker, in pursuit of a third consecutive victory at Deere Run, was among a group of 12 players knotted on 66.
