Herbert hits the front at Birkdale after dramatic second round

Lucas Herbert grabbed hold of a two-shot lead after an action-packed second round at The 154th Open Championship, which saw two players equal major history and Bryson DeChambeau being involved in a controversial rules decision.
DeChambeau had his strategy of playing the majors questioned before he arrived at Royal Birkdale after missing the cut at the Masters, The PGA Championship and the US Open, with the two-time major champion responding by following an opening-round 67 with a four-under 66.
