Stenson has struggled to get the year off to a good start as he missed the cut in Abu Dhabi last week, but he is hoping to improve in Doha.
The Swede said: "I hope to improve on last week's performance this week here.
"It's early in the year and a work%u2011in%u2011progress but I felt like I played half decent at least 18 out there. It was slow and fairly hot. Not as bad as it was yesterday, still a bit of wind.
"I don't know what the forecast is (in Doha), but normally we get our fair share of wind here, which is part of the course defence and makes it play better.
"I feel okay. I certainly have played better than I am doing but I'm sure we can probably find a few times where we played worse, as well."
Stenson also cheekily backed defending champion Sergio Garcia to win.
He said: "He's played really well around here and played this tournament a lot of times as well.
"That (putting Garcia as favourite) takes all the pressure away from me so let's do that."
