Day makes up ground in broken round
Former world number one Jason Day outshone playing partners Jordan Spieth and Rory McIlroy on a fragmented second day of the WGC-Bridgestone Invitational in Akron.
The start of play had been delayed due to a passing storm over Firestone Country Club and just over two hours' play was possible before the threat of lightning caused another 45-minute delay.
Day had managed to birdie the first hole in that time and carried on where he left off when play resumed, picking up shots on the second, third, fifth and ninth to cover the front nine in 30, despite appearing in some discomfort due to a back problem.
That took the 29-year-old Australian to four under par and just a shot off the lead shared by Jimmy Walker and Thomas Pieters, but as Day, Spieth and McIlroy prepared to play their second shots to the 10th, the siren sounded to suspend play once again.
Playing his first event since splitting from long-time caddie JP Fitzgerald, McIlroy had made the ideal start with a birdie on the second, but bogeyed the ninth following a wild drive to fall back to three-under.
Spieth, who is seeking his third win in succession after victories in the Travelers Championship and Open Championship, had also birdied the par-five second but carded three bogeys and a birdie in a four-hole stretch from the fourth to lie two under.
Before the first suspension Russell Knox had surged into a two-shot lead thanks to birdies on the first three holes, but the 32-year-old Scot bogeyed the fifth and seventh when play resumed.
A birdie on the ninth took Knox, who won the WGC-HSBC Champions in November 2015, out in 33, only for further dropped shots on the 11th and 12th to leave him alongside Day on four under.
Leona Maguire lies seven shots off the lead, held by South Korean In-Kyung Kim, after the second round of the Women's British Open at Kingsbarns in Scotland.
The Cavan girl, the current number one amateur in the world, carded a one-under-par 71 yesterday, which included three birdies and two bogeys.
Maguire posted an opening 69 on Thursday and is now four-under ahead of the final two rounds over the weekend.
Tandragee, Armagh amateur Olivia Mehaffey shot a 75 to end day two on three over, four shots short of the cut mark.
