Debutant Jon Rahm holds share of the lead at Quicken Loans National

Spanish debutant Jon Rahm showed his first round was no flash in the pan at Congressional as he kept a share of the lead in the Quicken Loans National.

The 21-year-old, who was the only amateur to make the cut in last week's US Open, followed up his opening 64 with a four-under second round of 67 in Bethesda.
