The U.S. Open's most famous runner-up is once again blasting the USGA.
Phil Mickelson took U.S. golf's governing body to task on Friday over speculation that the USGA will place a limit length on drivers to 46 inches from the current maximum of 48 inches. Mickelson uses a 47-inch driver that's presumably helped him maintain distance off the tees into his 50s. Not surprisingly, he's less than stoked about the potential regulation.

He took to Twitter to vent his thoughts:
Word is USGA is soon rolling back driver length to 46inches.
