(CNN) -- World number one Lee Westwood has used his Twitter account to express his anger at Rory McIlroy being snubbed for the U.S. PGA Rookie of the Year award.
Speaking after his superb eight-stroke victory in the Sun City Challenge in South Africa, the 37-year-old criticized the decision to give the honor to American Rickie Fowler, rather than to Ryder Cup teammate McIlory.
Westwood wrote on Monday: "Sorry 140 letters is not going to be enough for this rant. Just seen Rickie Fowler has been given rookie of the year.
"Yes he has had a good year but Rory McIlroy was third in two majors and demolished the field at Quail Hollow...oh yes and he was on the winning Ryder Cup team as well."
Westwood, 21-year-old McIlroy and Race to Dubai winner Martin Kaymer all declined to take up PGA Tour membership in 2011.
And on that subject, Westwood added: "This decision wouldn't have something to do with Rory not joining the Tour next year?
"Maybe the PGA Tour just employs the same voting process as FIFA," he continued, referring to the controversial choices of Russia and Qatar as football World Cup soccer hosts in 2018 and 2022 respectively.
