Jordan Spieth was locked in. Spieth shot a 5-under 65 to take and hang on to an early co-lead with U.S. Open champion Brooks Koepka at the 146th Open.

 

After making par at the first, Spieth pull-hooked his drive into some bumpy gorse off the second tee. From there, he hit an off-balanced approach that landed about 12 feet from the cup. He poured that in for birdie and never looked back.

 

Nobody shot a bogey-free round the last time the Open was here in 2008.

 

Bubba Watson, Hideki Matsuyama, and Ernie Els were in a group at two-under.

 

Adam Scott and Jason Day each finished the first round one-under while Dustin Johnson, Rickie Fowler and Rory McIlroy each finished at one-over after the first 18.
