Essex head coach Paul Grayson:
"We kept our discipline and our skills levels when we bowled and that was pleasing.
"We are in really good form at the moment in white-ball cricket and always fancy our chances of chasing down a total."

"We didn't score enough runs, it's as simple as that. We needed more runs in the powerplay.
"But Essex played very well and fully deserved their victory."
