The tournament will be played at the Jumeirah Golf Estates on Thursday.
When Garcia won the Omega Dubai Desert Classic last February at the Emirates Golf Course, with a three-stroke win over Henrik Stenson, he had said: "Hopefully it will be the beginning of a great year". "It's been a wonderful year".
Defending champion Matt Fitzpatrick is in the field this week after he won this tournament a year ago with a birdie at the 72nd hole.
After almost 12 months of hard work and toil - and the occasional slice of top notch golf - the European Tour campaign boils down to its curtain-call event: the DP World Tour Championship from Dubai. "Not at all, not at all", he shot back when asked if he regretted not winning the Race to Dubai crown.
"I'm not going to change the way I go out there", Garcia told a pre-tournament press conference.

The film had been cleared by the jury as had been another film, Nude , which did not meet with the approval of the I&B mandarins.
Rose will claim the title if he finishes first or solo second, and Fleetwood finishes third or lower.
It's all lush green rolling fairways, white sand bunkers (99 in total) and crystal-clear lakes (which patrol the last four holes in particular). They are not too firm at the moment but the course, a couple new lines.
"The US Amateur is also up there for me, it always will be one of my favourite wins, but to claim DP World Tour Championship in the way that I did, and the field I was up against, was very special and something I will never forget". "But other than that, it's good", he said about the 7,675-yard Greg Norman layout. "This is a place I've done well even before my win here last year - I finished fourth in 2015 - so I love the course and all being well I'll have a similar sort of result and end the year on a high". "What I'm going to do, I'm not going to change the way I go out there".
"What I'm going to do is I'm going to go out there and try to do what I do every week, which is to play the best I can play and give myself the best option of winning this week". I can't control what the other people do.
Rounds of 73 and 74 left Fleetwood off the pace through two rounds, but he shot 67 on Saturday to move into a tie for seventh at two under - six off the lead - and now has the opportunity to significantly enhance his current lead over Rose, which stands at 134,838 points. But I'm fine with it, I can live with it. "It's been a great year, and that's not going to change".
