AKRON – Back at one of his happiest hunting grounds for this week’s WGC-Bridgestone Invitational, Tiger Woods has spelt out what would transform a successful season for him on the PGA Tour into a great one.The American world number two has triumphed three times on the U.S. circuit in 2012 but has yet to add another major title to his career haul of 14 with his most recent coming at the 2008 U.S. Open."Winning golf tournaments makes it successful, but winning a major makes it a great year,” Woods told reporters at Firestone Country Club on Wednesday."You can go from having a ‘so-so’ year to all of a sudden winning one major and ... it’s a great year because you’re part of history when you do something like that.Woods was in contention going into the weekend at the last two majors before fading, finishing joint 21st at the U.S. Open and tying for third at the British Open.The final major of the year, the PGA Championship, takes place next week at Kiawah Island in South Carolina and he would dearly love to take winning form there from Firestone where he has triumphed a record seven times.Best playersWoods has generally thrived at Firestone. In 12 appearances at the tree-lined venue, he has claimed seven titles while his only finishes outside the top four came in 2011 and last year.A year ago, a rusty Woods tied for 37th here after ending a 12-week injury layoff. This week, though, is a very different story following his wins this season at the Arnold Palmer Invitational, Memorial tournament and the AT&T National.Woods (was due to) tee off in Thursday’s opening round in the company of South African Branden Grace.
