The award was announced on Wednesday and surprised no one.
McIlroy hit his stride in the summer and won the British Open and the PGA Championship, with a World Golf Championship in between. Those three straight wins catapulted him to No. 1 in the world.
McIlroy finished the PGA Tour season with three wins. He also led the tour with 12 finishes in the top 10, and he never finished worse than 25th. McIlroy also won the PGA Tour money title with $8.2 million, and he won the Vardon Trophy for the lowest adjusted scoring average.
McIlroy claimed 4th major title by age 25
With his two major championship titles this season, McIlroy doubled his career total to four just after his 25th birthday. This invites comparisons with Tiger Woods who has 14 majors, second only to Jack Nicklaus who has 18.
Woods won his first major in 1997 at age 21 with a dominant win at the Masters and compiled his total (4 Masters, 3 U.S. Opens, 3 The (British) Opens, and 4 PGA Championships) in a dozen-year stretch through 2008 when he topped the field at the U.S. Open to pull within four victories of Nicklaus. Injuries have plagued him the last few seasons.
McIlroy won the 2011 U.S Open at age 22, added his first PGA Championship the following year and secured his twin wins this year en route to his world No. 1 ranking.
Break-Up motivated McIlroy, Wozniacki
After announcing their engagement on New Year's Day 2014, McIlroy cancelled his wedding to tennis star Caroline Wozniacki, the former No. 1 ranked player from Denmark. Just after wedding invitations were sent out, McIlroy decided to call the whole thing off on May 21, shortly before the U.S. Open.
Since then both athletes have gone on to considerable success.
Wozniacki went to the fourth round at Wimbledon in July and followed with her first title of the year at the Istanbul Open over Roberta Vinci. She reached the final at the U.S. Open in September where she lost to Serena Williams but improved her World Tennis Association ranking, climbing back into the top 10.
In between his Grand slam titles in July and August, McIlroy won the World Golf Championship, returned to No. 1 status and then spearheaded Europe's winning Ryder Cup side at Gleneagles, Scotland last Friday through Sunday, as they trounced the United States for the eighth time in the last 10 match-ups.
