A rejuvenated Brooks Koepka took a three-shot lead into the weekend of the 87th Masters as Jon Rahm hoped the weather would not hinder his pursuit of the four-time major winner.

Koepka added a bogey-free 67 to his opening 65 at Augusta National for a halfway total of 12 under par, the joint-third lowest in tournament history alongside LIV Golf CEO Greg Norman.
