The 27-year-old Asian Tour number one is hoping that it will be a springboard that will end up making him his homeland's first major winner.
"It's quite amazing so much has changed," Lahiri said. "I didn't expect to be in this situation that I am now. I'm happy it has come and it's a fantastic time. I'm at a point in my career where I hope to move westward and the wins have helped. I'm excited."
Lahiri has won four titles in the last 10-months and his 34th world rankings puts him in position to play all four majors and grab a spot for the International team in this year's Presidents Cup.
This week will give Lahiri a test of how he stands against the US PGA elite.
"There will be a lot of firsts for me," Lahiri said.
"I'm really eager for all that. It's exciting times ahead and I will approach them in a similar manner. I'm trying to get better every day and will continue to work hard at improving my skills.
"One of the main things is to gain the experience of playing in the Majors and WGCs, playing well in them and in different conditions. It's all about learning as I go along and hopefully maybe I can get into the top-10 and vie for the number one spot.
"I just need to keep playing well and keep playing more in the big events to build up my confidence and ability to compete against the top players," he added.
