Rory McIlroy, one of the most popular pre-tournament favorites, is atop the leaderboard after the first day of the 2014 British Open. McIlroy shot an impressive opening round of 66, but several other great golfers are still in hot pursuit.
McIlroy must now battle not only them, but also his own demons that in too many recent tournaments have risen up to bite him in the second round or later.
Among those still in the hunt after Day 1: Tiger Woods, who shot a three-under par 69 for by far his best round since returning after a three-month layoff brought on by back surgery. Other notables include Jim Furyk, Sergio Garcia, Adam Scott and Brooks Koepka, all of whom are tied for third just two shots behind McIlroy. There's also some lesser-known players vying for the top spot, such as Matteo Manassero of Italy who is alone in second place after firing an impressive opening round of 67.
On a day when the course at the Royal Liverpool Golf Club was conducive to low scores—with the sun shining and very little wind blowing in off the Irish Sea—lots of golfers took advantage. But not all of them.
Read on to see who were the biggest winners and losers from Day 1.
