Assistant coach Matt Mason felt Worcestershire failed to post a substantial enough total as they suffered a five wicket defeat in the Royal London One-Day Cup clash with Gloucestershire at New Road.
Worcestershire looked set for a total approaching 300 after reaching 171-2 in the 35th over with Tom Fell (89) and Alexei Kervezee (80) batting well but the last eight wickets fell for 58 runs in 14 pvers.
Gloucestershire were set a revised target of 214 in 41 overs under the Duckworth-Lewis system and triumphed with 2.5 overs to spare.
Mason said: "I thought after a pretty tough start, losing two wickets quickly, we did really well to get to the powerplay stage of the game like we did and, after the powerplay, I thought we were in a fantastic position to probably get 300 again.
"Then unfortunately all I can say is there were some very poor decisions by our batters. Some of the shots were questionable at best and it (the score) wasn't good enough in the end and we left our bowlers with too much to do.
"If the guys reflect, as they will do, on the way they got out, a few of them will be disappointed.
"We've got set ideas as to how to play this 50 over competition and it's all about wickets in hand so you can post big runs at the end of the innings.
"When you lose wickets like we did, we weren't able to kick on and get that 300 plus score.
"The pitch didn't do that much early on but even if it did, you've just got to ride the storm knowing if you can get through that first period one or two wickets down at best, you've got that platform to get big runs."
Mason added: "We had to fight really hard with the ball, the guys threw everything they could at it. But we did not have enough to defend.
"It was a good shout at 10-3 but the two guys who came together (Ian Cockbain and Gareth Roderick) showed that if you bat properly, bat time and stop the fall of wickets, any score is really chaseable in this competition.
"I thought when we got the early wickets, if we could keep on taking wickets, that we had a chance to defend that total but once they got that big partnership, it was starting to look a little bit bleak I'm afraid.
"Credit to big Mitchell McClenaghan, for example, who came in and tried really hard, got us the important wicket late in the game of Will Gidman and gave us a little chance.
"But Ian Cockbain (98 not out) did a fantastc job to bat through the innings for them like he did."
Worcestershire opted not to play a spinner and operate with an all-seam attack.
Mason said: "I think we've noticed in the last couple of games that the new ball has nipped around.
"We sort pf hedged our bets a little that we might win the toss and our four seamers could do the job for us.
"Again if we had 300 on the board, I think that would have been the right selection. The four quicks have done the job for us all year so why not try them in this form of the game."
