Defending Open champion Zach Johnson was upbeat over his first-round performance at Royal Troon despite a bogey-bogey finish.
Johnson had been six under through the first 16 holes on Thursday, but dropped a shot on each of the final two holes.
That disappointing conclusion to his round leaves Johnson four strokes off leader Phil Mickelson in tied fourth.
But, while he accepted he had no excuses for his poor finish, the two-time major champion was keen not to let it detract from a strong start to his defence of the Claret Jug.
"Quite honestly it's probably what I deserved. I mean, granted, to shoot in the mid-60s, you're going to make putts, but I don't know if it evened out or not," Johnson said.
"I hit really two errant shots coming in, and I hit some I guess you'd say approach shots, pitches, and misjudged the putts, misread the putts, but two really errant shots that cost me.
"And if anything, you know, you get to those situations and you're just trying to eliminate the big, big one, and I still had chance to make pars.
"Tough pin on 18, and I didn't hit a very good putt on 17. I mean, it's not going to take away from a really solid day.
"I think I hit the first 10 greens in regulation, so it wasn't like there was a whole lot of stress there. It wasn't like I was knocking down pins, but I put myself in position to certainly make some putts.
"I missed a couple there the first six, seven, eight holes, but I made a few, too, so probably evened out."
