Lahiri said: "It is now time to put into action all that I have prepared for."
Lahiri, who is playing his fourth Major in a row, added, "It is now time to do well and a make a mark at this level."
While doing well at Majors is the big goal for Lahiri, he also nurses the dream of winning the Asian Tour Order of Merit, which has in the past been won by only three Indians - Jyoti Randhawa (2002), Arjun Atwal (2003) and Jeev Milkha Singh (2006 and 2008).
While Lahiri has two wins this year in co-sanctioned event, Thongchai Jaidee, has had two runner-up finishes in Thailand and England this season. Jaidee has two wins on European soil - in Wales (2012) and in Sweden (2014). He has been paired with South Africa's Brenden Grace and American Brendon Todd.

At the global level, there will be a lot of focus on Jordan SPieth, winner of the Masters this year and Rory McIlroy, who won the US Open in 2011. McIlroy won two Majors in 2014 and he was tied eighth at Masters and T-23 at PGA.
Tiger Woods, whose last Major was the US Open in 2008, is also in the field and despite his finishes way down in the field he himself feels he is slowly coming back to where he wants to be and it is a "work in progress".
