The American concluded last season with back-to-back victories in the FedEx Play-Offs at the BMW Championship and season-ending Tour Championship.
Although his brace of wins came too late to qualify for the US Ryder Cup team, he ended the calendar year ranked 13th in the world.
The Florida-born player is in the field for this week???s Hyundai Tournament of Champions at Kapalua???s Plantation Course in Hawaii, an event restricted to those golfers who won official PGA Tour events during 2014.
And Horschel told a pre-tournament press conference: “Last season was unbelievable. Before the play-offs my season had not been going the way I would have liked.
???But I was able to find something at the Deutsche Bank in Boston where I was second and kept that momentum going at Denver and at the Tour Championship.
“And two wins back-to-back, I don’t think I’ve ever done that in my golfing career at whatever level. And obviously to win the FedEx Cup is life-changing.
Asked about his future ambitions, Horschel added: “I’m trying to see how great a player I can be, reach my level and my potential as a player, and I’ve got to keep getting better.
???One of the things I want to do is be a little more consistent this year.
“I think one reason I wasn’t very consistent last year is I putted really badly. I putted awful until those last three events and my short game can get better.
???And I think I made some strides this off-season in working and getting better technique-wise.”
Another pro among the 34 teeing-up in Friday???s opening round at Maui is Bae Sang-Moon.
The South Korean has vowed to take legal action after his government refused to extend his visa, meaning he is required to return home and face two years of compulsory military service.
The 28-year-old said: “I got the green card to work in the US. If I have a green card, I can extend five or six years more.
???I don’t know why they didn’t approve an extension. I will take legal action. I couldn’t understand why they denied it.”
