Lowry's ball moved after a practice swing, but did he cause the movement? That's the question tournament officials were left to answer.

But, with 36 holes left, the Claret Jug is still very much up for grabs. Scheffler is paired up with Matt Fitzpatrick, who held a share of the lead after Thursday and then backed that up with a 5-under 66 on Friday. He's starting just a shot back from Scheffler. Brian Harman and Haotong Li are tied at 8-under to start the day, too.
