The free-flowing Agathangelou went in pursuit of the challenging 173 for eight struck by the Nashua Phantoms in a gung-ho way.
He hammered a six over cover and a maximum over deep square leg off the first two deliveries he received.
The shell-shocked Phantoms did not recover and Agathangelou did not relent. He blasted 92 off 28 balls with eight fours and nine sixes. Pirates reached 178 for four in 16.4 overs to win by six wickets.
Eldred Hawken, who scored 31 off 39 balls, was an admiring spectator at the bowler’s end while Agathangelou produced mayhem.
“He played shots all around the wicket. My feeling is that it is great news for the Multiply Titans if Heino Kuhn, Aiden Markram and Dean Elgar are lost to the South African team. It means we have an opener in reserve,” said Nashua Tshwane Phantoms bowler, Shaun von Berg.
The leg-spinner nipped out 1-27 in 3.4 decent overs and earlier managed a solid 32 off 28 balls.
He assisted Danie Rossouw, who struck 49 off 25 balls to get the Phantoms to a presentable 173 for eight.
“I was very impressed with his performance at the top of the order,” added Von Berg.
Von Berg said losing the toss was a factor, because the wicket flattened out after 90 minutes and when the Pirates batted; it was much easier than in a testing early morning spell.
Vandiar was in prime form for the Mavericks, bludgeoning 109 off 58 balls with six fours and 10 sixes. They reached 195 for five.
The Quatro Cougars could only muster 166 for seven. They lost by 29 runs, despite the threatening presence of Albie Morkel.
Morkel conceded 10 runs in two overs while all the other bowlers suffered.
The all-rounder also hammered 58 off 28 balls at a strike-rate of 207, but did not receive enough support from the other end.
Ryk Eksteen contributed 55 off 44 balls.
Vandiar said one of the highlights for him was the bowling performance of a very young attack. They stuck to their task excellently.
Asked about his own knock, he said he spent the off-season in Holland and rarely took his eye off the proverbial ball. “I am getting back to the form I had before the few seasons at the Dolphins.
“It was a very good wicket, and the boundaries were short. I used the flick well over square leg or fine leg.
“I was also lucky, because I was bowled with a no-ball with my score on 71,” he said.
Vandiar was superb during the Momentum One Day Cup series last season. He scored 296 runs at an average of 42.28.
He fashioned an opening partnership of 313 with Henry Davids at PPC Newlands. His 153 was one of the highlights of the season which ended in a triumphant 236-run win in the final of the Momentum One Day Cup against an outclassed Warriors.
“My campaign was made easy for me by the way that Aiden Markram and Henry Davids batted at the other end in the 50-over series,” he said.
“I have liked working with Mark (Boucher) and Mandla (Mashimbyi) as coaches. I am a laid-back guy, and they haven’t tried to change me. That has been beneficial to me,” he concluded.
Day two will see the Phantoms take on the Mavericks from 10:30 before the Cougars take on the Pirates at 13:30.
