Chris Gayle hit the first Caribbean Premier League century as the Jamaica Tallawahs beat the St Lucia Zouks and there was also a win for the Trinidad & Tobago Red Steel over the Barbados Tridents.
Gayle blasted 111 in just 63 balls to hammer the reigning champions to a convincing seven-wicket win over the Zouks, who saw their score of 161 for five overhauled with an over to spare.
Gayle hit five fours and 10 sixes on the way to a 60-ball century - his 12th in Twenty20 cricket - as he smashed the Zouks bowling to all parts.
Chadwick Walton (23), Jermaine Blackwood (8) and Adam Voges (15) offered Gayle support but St Lucia's inability to dismiss him cost them dear.
While Sohail Tanvir (1-14) and Shane Shillingford (1-18) were outstanding, the others were savaged.
Henry Davids had earlier top scored with 56 in 38 balls to guide the Zouks to a competitive total. Johnson Charles (27), Andre Fletcher (27) and Darren Sammy (29 not out) also made useful contributions.
In the other match, half-centuries from Ross Taylor and Darren Bravo eased Red Steel past a modest target of 125 with more than two overs to spare.
Batting first, Barbados struggled after being given a good start by Shane Dowrich, who made 37. Dwayne Smith hit 13 and Shoaib Malik 21 but runs did not come quickly enough.
Jason Holder, who carved 17 in nine balls at the death, was the only player to score at a strike rate of more than 100.
Dwayne Bravo picked up two for 17 and Kevin O'Brien two for six.
In reply, Red Steel lost Nasir Jamshed for a golden duck and Even Lewis for four only for Taylor (62 in 51 balls) and Bravo (54 not out in 42 balls) to put on 95 together to take their side to the brink of victory.
Wicket-keeper Nicolas Pooran was unbeaten on one as the winning runs were hit.
The next round of matches see the Antigua Hawks host the Jamaica Tallawahs, the Barbados Tridents and the Red Steel while the Guyana Amazon Warriors host the Red Steel, the St Lucia Zouks and the Jamaica Tallawahs between 17th and 20th July.
