The 31-year-old Johnson gave an object lesson in big hitting as he bulldozed his way to a pacesetting seven-under-par 65 in becalmed early weather conditions.
Jordan Spieth got his Open campaign off to a promising start at St Andrews on Thursday, but in the end he had to bow to playing partner Dustin Johnson who leads after the first round.
Lahiri is getting Divecha to iron out glitches here and there to suit the Old Course.
There are intriguing subplots surrounding Spieth's bid for golf immortality. One is the possible emergence of an unlikely winner like Louis Oosthuizen.
"I'm still young. I'm not 40 yet," said Woods, who has five months left in his 30s.
"Total rupture of left ATFL (ankle ligament) and associated joint capsule damage in a soccer kickabout," McIlroy wrote on his Instagram account.
Star Indian golfer Anirban Lahiri is be looking to reap the benefits of having the support of his entire family at St Andrews when the British Open gets underway in a fortnight.
McIlroy is especially delighted with the state of his mental approach to the game, though he is wary of any media hype that the sport is entering a 'Rory era' of individual dominance.
McIlroy was 15 at the time of the wager and is now 25.
Rory McIlroy completed a wire-to-wire victory Sunday in the British Open to capture the third leg of the career Grand Slam.
McIlroy seemed in real danger of missing his share of the birdie feast which allowed 16 players to post sub-70 rounds.
Lahiri, who has won once this season and posted three more top-10s on the Asian Tour, said he wasn't sure if he would conclude his round under the steamy conditions.
Several second round blow-outs this season, the most recent at the Scottish Open, meant all eyes were on the 25-year-old Northern Irishman to see if he could capitalise on his one-stroke overnight lead rather than shoot himself in the foot.
As the mercury rose, Woods responded with a scorching back nine containing five birdies in six holes to card an ominous three-under par 69.
Anirban Lahiri stumbled to a couple of late bogeys to return a disappointing three-over 75 on the opening day of the Open Championships here today.
Among the morning starters at the Open was Tiger Woods who has just returned from back surgery.
Coming back to Hoylake for the first time since 2006, the question marks that surround Woods are as pertinent as ever before.
"Total chaos. Will have to make it up to the wife big time. Super excited," said Lahiri, a four-time winner in Asia.
Mickelson's win eclipsed his previous best British Open finish of tied second in 2011.
Mickelson shot a 5-under 66 Sunday to match the best round of the tournament and win his first claret jug.
