Masters and U.S. Open champion Jordan Spieth fell one stroke short of adding The Open to his 2015 haul, ending hopes of a calendar Grand Slam.

The American came to St Andrews as overwhelming favourite after taking the year's first two majors and the pre-tournament withdrawal of world number one Rory McIlroy.

Solid first and third rounds were hampered by an even-par second round, which was spread over Friday and Saturday thanks to unpredictable Scottish weather.

Six birdies on Monday's rescheduled final round had Spieth right in contention, despite a double bogey at eight.

However, another dropped shot at the challenging par-four 17th left Spieth needing to birdie the last to join Marc Leishman and Zach Johnson on -15 for the tournament.

A poor tee shot was followed by an approach that rolled back down the slope, leaving Spieth needing a miracle put reminiscent of Costantino Rocca's 1995 play-off-forcing heroics.

However, the 21-year-old's effort fell just wide, though he can perhaps take solace from joining exalted company in the form of Arnold Palmer - a Masters and U.S. Open champion in 1960 who too fell a shot short at St Andrews.
