O’Sullivan, 36, resumed the day 10-7 ahead and wrapped up proceedings in under an hour.
Rocket Ronnie’s fellow Essex player Carter managed to win three frames in a row to take the match into a final session, however the 32-year-old couldn’t control the magnificence of O’Sullivan.
The fourth time World Champion took the first four frames, including a quick fire-break of 101 after resuming the day.
After this win O’Sullivan immediately announced he would be taking a six-month sabbatical from the sport. This break from the game comes at a time when O’Sullivan future in snooker is uncertain with rumours of his retirement circulating around the sport.
O’Sullivan said: “I am going to enjoy my time off with my family and then assess the situation, but it’s all good and I want to enjoy the moment.”
Ali Carter has now finished World Championship runner-up for a second concedes O’Sullivan was just simply unplayable.
Carter said: “The better man won. He’s a genius. It’s the Ronnie O’Sullivan show isn’t it?”
O’Sullivan adds this title to his 2001, 2004 and 2008 World Championships and we shall all have to wait and see what is next in store for Ronnie.
