US Open 2015: Tiger Woods says he is on 'the right track'

Three-time winner Tiger Woods says he is lacking consistency and is still rusty following back surgery after making a "tough" start to the US Open.
Woods, 39, shot a 10-over-par 80 in the first round at Chambers Bay, and is already 15 shots behind  the leaders.
"It's one of those things, I've just got to work through it," the former world number one said.
"I'm trying as hard as I can to do it, I just can't get the consistency that I'd like to have out there."
Fourteen-time major winner Woods registered a triple bogey on the 14th and is well behind leaders Dustin Johnson of America and Sweden's Henrik Stenson who are on five under
.
Only Rich Berberian Jr, a club professional playing in his first US Open, and Rickie Fowler had worse rounds.
A birdie at the 16th was the lone bright spot before Woods finished with a bogey to leave him tied 152nd, one shot clear of Fowler and three in front of Berberian.

Woods has been hampered by a back problem for some time.
The American missed the 2014 Masters, a competition he has won four times, after having surgery on a pinched nerve in his back before withdrawing from the 2014 US Open.
Woods also withdrew from the Farmers Insurance Open at Torrey Pines in February because of it.
