CROMWELL, Connecticut – Sweden's Fredrik Jacobson prolonged his love affair with the Travelers Championship when the title-holder grabbed the lead in a rain-hit second round Friday. Jacobson picked up four birdies and an eagle in a four-under 66 for a nine-under total of 131, his sixth straight round of 66 or better on the TPC River Highlands layout. US Open champion Webb Simpson shot a 69 to remain within striking distance, four strokes behind the Swede on 135. Rain stopped play for the day in mid-afternoon and 77 players must return on Saturday morning to complete their rounds. Jacobson went out in the early groups and after opening with a par on the 10th, his first hole, went birdie-birdie-eagle to soar up the leaderboard, the run highlighted by a 40-foot putt for eagle on the par-five 13th. Americans Blake Adams (64) and Roland Thatcher (67), and Australian Stuart Appleby (65), were a shot further adrift at seven-under 133. Park leads at Waterloo South Korean Inbee Park fired a seven-under par 64 Friday to seize a one-stroke lead in the second round of the storm-interrupted $1.3 million Manulife Financial LPGA Classic at Waterloo, Canada. Needing only 22 putts, Park made eight birdies against a lone bogey to stand on nine-under par 133 after 36 holes, one stroke ahead of American Brittany Lang, South Korean Hee Kyung Seo and China's Feng Shanshan. A storm Thursday forced the first round to be completed Friday morning and the second round nearly beat the darkness, but seven players will have to return to Grey Silo Golf Course Saturday morning to complete their final one or two holes. None was within seven strokes of the lead. Willett ahead England's Danny Willett remained in pursuit of his first Tour victory after shooting 69 Saturday and leading by a shot at 12-under after three rounds of the BMW International Open at Pulheim, Germany. The 24-year-old Willett moved clear of England's Chris Wood (70) and Chilean-born Swede Joel Sjoholm (72) on the Gut Larcenhof course in Pulheim. Willett has only returned to form in the past three months after he tore a rib muscle in 2010. While Willett chases a first Tour win, so too do Wood and Sjoholm. Wood burst onto the international stage in finishing tied with England's Lee Westwood and capturing the ‘Low Amateur' award at the 2009 British Open at Turnberry. Scotland's Colin Montgomerie marked his 49th birthday with a par 72 that included three bogeys over his closing five holes to remain at 1-under.— Agencies
