The world number one from Holywood hit seven birdies to carry him into a tie for third place on 10 under, two shots behind leader Russell Henley of America.
McIlroy, who has won three of his last four competitions, made a fantastic start in Boston on Sunday with birdies on holes two and three.
The 25-year-old then went to three-under at the seventh after driving a 132-yard approach to nine feet and holding his nerve to make the putt.
More birdies followed on the 10th, 13th and 15th and Rory was inches away from acing the 16th - but was nevertheless able to tap in to go seven under for the day, leaving him well and truly in contention for a chance to add to his recent Open, WGC-Bridgestone and US PGA victories.
"I converted some more of the chances that I gave myself today," the Ulsterman told Sky Sports.
"I was pretty frustrated coming off the golf course in the last couple of days because I felt like I left a lot of shots out there.
"Even today, I felt like I might have left a couple out there, especially on the last. But I'm happy with how I converted those chances and I'm going to need to do the same tomorrow if I'm going to win."
