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.

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