( CNN ) -- Tiger Woods sizzled at the WGC-Bridgestone Invitational . With the season 's final major a week away , his timing is good . Woods equaled his career-best round on the PGA Tour and matched his own course record in Ohio by shooting a 61 , hitting an eagle , seven birdies and not dropping a shot . He also shot a nine-under-par 61 in the second round of the tournament in 2000 -- the year he outclassed his rivals and claimed three majors . But Woods has n't won a major in five years now , stuck on 14 , and struggled on the final day of the British Open last month when he was in contention . The Bridgestone Invitational was the world No . 1 's first tournament since Muirfield , and he began with an impressive 66 . He bettered that on Friday at a tournament he has captured seven times , beginning with a birdie , eagle and birdie to set the tone . Woods shot the first nine in 30 . `` I just let the round build from there , '' Woods said in a television interview aired by Sky Sports . `` I made a couple of key putts for pars . Things like that happen today . '' The back nine started just as well , with Woods registering four straight birdies . He was nine under through 13 holes . With a sub 60 round in his sights , though , Woods shot at par the rest of the way , narrowly missing a birdie on the 17th but then avoiding a bogey on the 18th with a stunning putt . He leads defending champion Keegan Bradley and England 's Chris Wood by seven shots . `` It put me in a nice position going into the weekend , '' said Woods . The last time Woods shot a 61 at any tournament was at the 2005 Buick Open . Before looking ahead to the PGA Championship , Woods was focusing on finishing the job at the Bridgestone Invitational . Thunderstorms are expected Saturday . `` We got a long way to go , '' said Woods . `` The golf course will be certainly a lot different than it is now with the weather coming in so we 're going to have to make a few adjustments and see how it goes . '' British Open winner Phil Mickelson was tied for 43rd . The slumping Rory McIlroy was tied for 25th alongside U.S. Open winner Justin Rose , 14 shots behind Woods . Park eight shots behind at St. Andrews . At the women 's British Open at St. Andrews in Scotland , meanwhile , Inbee Park has work to do if she wants to become the first golfer in 83 years to claim four majors in a single season . Through two rounds on the Old Course , Park trails fellow South Korean Na Yeon Choi by eight shots after registering a 1-over-par 73 in blustery conditions . She is tied for 22nd . `` A little bit of everything was n't really working well out there today , '' Park told reporters . `` I think I grinded ( it out ) really well out there . `` I was a bit unlucky with the draw , getting afternoon today , not playing in the morning when it 's lovely . '' Choi , last year 's U.S. Open winner , leads Japan 's Miki Saiki by a shot , with overnight leader Morgan Pressel of the U.S. a further shot behind .
