The U.S. Open typically plays as a par 70, which requires converting a couple of par 5s into par 4s. There are a few par 71s, such as Torrey Pines, where USGA setup man Mike Davis wisely decided to leave the 18th as a par 5, leading to one of the most memorable finishes. Par has not been decided for Chambers Bay outside Seattle, site of the 2015 U.S. Open. It could be a par 70. It could be a par 71. It very likely will be both. "You can't change par in the middle of a tournament," Tiger Woods said, thinking aloud as he tried to process the possibility. Considering that Davis isn't afraid to break the unwritten rules, the possibility is very real. "One thing I'm absolutely positive we'll do in the future, perhaps in 2015 at Chambers Bay, is play a hole certain days as a par 4, and certain days as a par 5," Davis said in a telephone interview over the weekend. Davis mentioned the first and 18th holes at Chambers Bay, which he felt could be played as either a par 4 or a par 5.
