It sounds like he wasn't tested twice, his sample was.
Rahm has tested negative every day, but his most recent test – which was performed after the conclusion of his second round (rain delayed) and before the start of his third round – returned positive at approximately 4:20 p.m. ET while Rahm was on the golf course. The PGA TOUR’s medical advisor requested a confirmatory test on the original sample, which came back at 6:05 p.m. ET, and was also positive.
I can't say whether it was a tainted sample and a new sample would test otherwise, or it was a good sample that was positive for COVID-19. I would think that Rahm would want a fresh sample tested, just to be sure.

You are correct. I wasn’t clear in what I was trying to say.
