The 2015 Open Championship was a men's major golf championship and the 144th Open Championship, held from 16 to 20 July at the Old Course at St Andrews in Fife, Scotland. It was the 29th Open Championship played at the course and Zach Johnson won in a four-hole playoff for his second major title. Inclement weather – which included heavy rain and very strong winds – forced play to be suspended twice, on Friday and Saturday, with the latter having play suspended for nearly most of the day. The third round was held on Sunday and the final round (and playoff) on Monday.
