What our Post expert thinks about the Open Championship
One of the great things about the Open Championship is that conditions can change on a dime.
The coastal, links-style courses on offer are at the mercy of Mother Nature, and we could see some wind and precipitation throughout the afternoon in Southport.
Keep an eye on the conditions and get ready for chaos.
Must be 18 years or older and have a legal, U.S. residential address within the applicable state, D.C., or U.S. territories. Not available in AZ, IL, MA, MD, MI, MT, NV, and OH.
