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.

World number one Rory McIlroy withdrew prior to the tournament due to an off-course ankle injury; he was the first defending champion absent from the Open in over sixty years, since Ben Hogan opted not to participate in 1954. Masters and U.S. Open champion Jordan Spieth attempted to win a third consecutive major and take over the top ranking. He finished one stroke out of the playoff, in a tie for fourth.

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.

This was also the last Open Championship played under the then present TV deals with the BBC and ESPN each having their swan song. NBC and Sky Sports would take over coverage the following year at Royal Troon.

This was the final Open appearance for five-time champion Tom Watson and three-time champion Nick Faldo who played in his last major championship.

Venue

The 2015 event is the 29th Open Championship played at the Old Course at St Andrews. The most recent was in 2010 when Louis Oosthuizen won his only major title and became the second South African to win an Open Championship at St Andrews (Bobby Locke is the first, having won at St Andrews in 1957).

Second round Friday and Saturday, 17–18 July 2015

The first group teed-off at 6:32 am BST on Friday, but heavy rain caused localised flooding and play was suspended at 6:46 am. Restarted at 10 am; later tee times were delayed over three hours . The tee time for the 52nd and last group was delayed from the original 4:13 pm to 7:27 pm. The second round was not completed on Friday and 42 players returned early Saturday to finish their

Dustin Johnson was the overnight leader on 10-under-par after 13 holes, a stroke ahead of Danny Willett. The day marked the final Open appearance of five-time champion Tom Watson at age 65.

Play resumed on Saturday at 7 am, with the third round due to start at 11 am. However, play was soon suspended at 7:32 am because a strong wind was moving stationary balls on some of the greens. Because it was a non-dangerous situation, players were allowed to complete the hole they were playing. Dustin Johnson had bogeyed the 14th to move back to 9-under-par, tied for the lead with Willett.

After a delay of several hours, it was decided that only the remainder of the second round would be competed on Saturday, with the third round scheduled for Sunday and the fourth round for Monday. Play finally resumed at 6 pm, a 10½ hour delay, and was completed after 9 pm. The 36-hole cut was at even par 144 and eighty players advanced to the third round.
