World-number-three Jordan Spieth described his five-under-par opening round of 65 at The Open Championship as a “top five major round” of his.

On the back of a win at the Travelers Championship a month ago, Spieth headed to Royal Birkdale full of confidence and transferred that to a bogeyless opening round to take a share of the lead with Matt Kuchar and US Open champion Brooks Koepka.

“Given the forecast coming in, I thought you really needed to be in the red,” the 23-year-old said.

“Everything was strong. I would give it a nine across the board for everything: tee shots, ball-striking, short game and putting. Things are in check; it’s just about keeping it consistent.

Spieth will attempt to solidify his position atop the leaderboard as he tees off his second round on Friday at 14:48 GMT.
