PORTRUSH, Northern Ireland -- The Latest on first round of The British Tiger Woods says he was "sore" during his round of 78 at the British Open and wasn't moving as well as he did in winning the Masters in April.
The 15-time major champion says there are certain shots he can't hit the way he used to because of "Father Time and some procedures I've had over time."
Woods had four back surgeries in a span of about three years to 2017.
Woods, who made six bogeys and a double bogey, said his warmup wasn't very good and that he was "just trying to piece together a swing that will get me around a golf course."
Woods puffed out his cheeks and looked glum after bogeying the last hole for a 7-over 78, his worst opening round at a British Open.
His highest first-round score at golf's oldest major before this year was 76 at St. Andrews in 2015.
Woods' rough patch at Royal Portrush came around the turn, when he made four bogeys and a double bogey in a span of six holes. His only birdie came at the par-4 15th hole - and he reacted by spreading out his arms and licking his finger.
With Rory McIlroy shooting 79, two of the biggest names in golf are struggling to make the weekend.
