JOIN USGayle force blows Lanka away
The tall left-hander smashed the ball all around the ground, batting throughout the day to finish unbeaten on 219 off 247 balls.
Gayle's chanceless effort comprised eight sixes and 26 fours on a placid pitch. Shivnarine Chanderpaul was batting on 20 when stumps were drawn.
The opener, who has a top Test score of 317, reached his 13th century by hitting Ajantha Mendis for two consecutive sixes in an expensive over which cost the spinner 18 runs.
Gayle celebrated with arms raised, flashed a broad grin, took off his helmet and lay flat on the ground to milk the applause.
He was less exuberant upon reaching his double century with a single.
Gayle had a scare on 65 when Sri Lanka used the referral system for an lbw decision off Mendis and television replays showed he got an inside edge on to his pads.
The former skipper was particularly severe on Mendis and fellow spinner Suraj Randiv, who went for a combined total of 234 runs.
Gayle and Adrian Barath put on 110 for the first wicket after Darren Sammy won the toss on his debut as Test captain.
Barath was dropped by Randiv on 35 after offering a head-high return catch but the spinner eventually got his man when he was caught at slip by Mahela Jayawardene on 50.
Darren Bravo then helped Gayle in a second-wicket partnership of 196, a record for any wicket between the two countries.
Bravo made his maiden Test half-century and was then dropped at short leg by Tharanga Paranavitana on 50.
He finally fell eight runs later when he top-edged a pull off Mendis to square leg.
