It wasn’t quite Steve Harmison, Rory Burns or Zak Crawley.
But as first balls as indicators of what is to follow, Jacks easing David Willey’s first ball back down the ground for four wasn’t half bad.
There was a confidence to the shot, the opener backing his timing, not trying to smash it out of the park and still knowing it would get to the boundary.
The fireworks could come later – and they did.
After bludgeoning his 51st and 52nd sixes – the second most overall in the history of The Hundred – the only surprise was that Jacks did not kick on to get his century.
A strike-rate of 175.60 shows he was not holding back but the control he showed from the first ball was there throughout as he took down the Rockets attack.
Stoinis’ slower ball eventually did for him with 15 balls left in the innings and, despite Invincibles’ usual explosion of boundaries late on not coming, the damage to the Rockets was done.
This is an Invincibles side that is just used to winning, a few early boundaries for Banton were not going to bother them.
Sowter’s three-wicket spell knocked the stuffing out of the Rockets and from there, the Invincibles – for the third year running – were able to largely cruise to victory.
