Anirban finished in a share of third place with an impressive display at the CIMB Classic in Kuala Lumpur for his best performance at a PGA Tour event.
Having started with back to back rounds of 66, Anirban went one better with a stunning round of 65 on Saturday to lead by four strokes heading into the final day.
That advantage was wiped out when Anirban took a nine on the par-five third hole. He birdied the next and then eagled the sixth as he turned at one over par for the day.
With one more birdie on the back nine, he shot 72 and was beaten by Justin Thomas, who ended the week with a round of 64.
Anirban was frustrated at the way the final day panned out and said: “I’m disappointed obviously. It was obviously a harder start. I got unlucky with the tee shot and just compounded my errors, my short game again, coming up a little bit to bite me.
“But obviously I tried my best. I fought back as best I could, but I just couldn’t get the putts to fall on the back nine. I had numerous lipouts and then just really disappointed that I didn’t birdie 17 or 18 or even 16, for that matter. I just didn’t get the numbers right with my wedges. I didn’t hit them close. It’s very disappointing.
“I would have obviously liked to have gotten over the line, but it’s a tough pill to swallow.”
After a week's rest, Anirban is set to travel to Antalya for the Turkish Airlines Open before PGA Tour events – the OHL Classic at Mayakoba in Mexico, starting on November 10, and The RSM Classic at the Sea Island Resort the following week.
He moves up to 68th in the Official World Golf rankings and is eighth in the early season FedEx Cup points list.
Anirban’s solid week in KL follows on from his play-off defeat at the Venetian Macao Open and top-30 finishes at the Porsche European Open and the BNI Indonesian Masters presented by Zurich.
Despite being disappointed with his finish, Anirban is full of optimism for the season ahead.
He added: “There are lots of positives. Obviously I’ve made a lot of birdies over these last five rounds that I’ve played. I’m in a good place. I’m off to a decent start, good start I would say, on the PGA Tour but again, just missed out on a large number of FedExCup points, World Ranking points, just down the stretch in the end so I’m feeling a bit disappointed with that, yeah.
“Whenever I tee it up next, likely to be in Turkey, hopefully I can put myself in this situation again. The only thing I can look at, if I keep putting myself in contention, I’m bound to convert one sooner rather than later.
“I have the confidence. It’s not like I need additional confidence. But I need validation now. I need validation in terms of my game. I need to see that happen. It’s just not happened enough, and it’s been a year of near-misses so far.
“I mean, it’s a good problem to have I guess, but it’s something that I want to change obviously the rest of this season on the PGA Tour. It’s not the way I would like to play on a Sunday, not at all. It’s hard.”
