‘Richie Lock batted beautifully but after he was caught at short fine-leg we lost our momentum.
‘Two silly run outs didn't help our cause.
‘In the end we didn't have enough runs on the board.
‘Bashley bowled well and looked a good side.
‘We will regroup and get ready to go again because nothing is won or lost in the first game of the season.’
