Rain Rain, GO AWAY!!

Well, after a short 3 hours at the US Open, play was suspended due to a down pour of rain. And there is no end of the continuing rain in sight!

Puddles formed on some fairways, too, most notably at the 18th hole, which is built on a swamp. The 18th green, which is elevated, was virtually underwater when play was suspended.
The poor drainage at No. 18 -- it has had to handle nearly 30 days of rain since the beginning of May -- could provide an interesting wrinkle at the end of this championship.

USGA rules do not allow for a U.S. Open champion to be crowned in fewer than 72 holes, so play will continue until all four rounds can be completed. That means a Tuesday or Wednesday finish is not out of the question, especially considering the USGA was expecting rain through the weekend and into next week.
