Mick Newell remains confident the Notts Outlaws can quickly turn around their form in the Friends Provident Trophy - but warned his batsmen they need big scores to win matches.
Yorkshire Phoenix 280-4
Notts Outlaws 243 (Read 68, Wagh 56)
Yorkshire Phoenix won by 37 runs
Former Notts batsman Younis Khan hit 100 to help Yorkshire to victory and with the Outlaws top five unable to match his efforts, Chris Read's late 68 (pictured) came too late to make any impression.
But while Newell will be pushing his frontline batsmen to turn good starts into match winning totals, he also saw plenty of positives in the game.
He said: "The pitch was a good one for batting on and in the circumstances I thought we bowled and fielded well.
"We felt 280 was a par score and that if we applied ourselves we had a chance of hunting it down.
"But losing our top five without one of them batting through the innings meant we were never going to get close.
"Numbers three, four and five got in and then got out without winning it for us. Pretty 30s, 40s and 50s won't win matches and someone needed to do what Younis did."
David Hussey invited Yorkshire to bat after winning the toss in the hope of exploiting some early help from the wicket.
But while Ryan Sidebottom and AJ Harris kept things tight and tested out openers Jacques Rudolph and Craig White, it took a mix-up between the two and a run-out to break the partnership with Rudolph heading back to the pavilion.
Paul Franks quickly followed up to bowl White but Younis then combined with Gerard Brophy to keep the scoreboard ticking.
Good work in the field limited the number of boundaries but when Mark Ealham removed Brophy lbw, Andrew Gale came in and maintained the run-rate.
Tight bowling at the death from Franks and Sidebottom ensured there was no late flurry of runs but things looked more tricky after Notts lost two wickets in the first 10 overs.
Both Bilal Shafayat and Jason Gallian were bowled but Mark Wagh and Hussey recovered the situation from 22-2.
The pair's aggressive approach added 65 in nine overs until Hussey's attack on Deon Kruis - who conceded 21 in the over - saw the Aussie become too adventurous and hole out at cover.
Wagh was then bowled by Chris Gilbert, Samit Patel found long-on for 36 just when he seemed to be getting into action, leaving Read with too much to do as wickets fell regularly.
Newell was not too downbeat after the match and added: "We will need to get back on track and get a win quickly but we are capable of doing that and improvement is certainly possible.
"What lost us the game was some mistakes and poor shot-selection rather than things we can't put right.
"We did well in the field and some of the ball-striking was good for early in the season, so we must build on that and produce a more complete performance against Northants next weekend."
