MARTYN Moxon believes Yorkshire’s fielding cost them the chance of making it two wins from two in the NatWest T20 Blast at Chesterfield on Saturday.

The Vikings lost a thriller by three runs against Derbyshire Falcons, failing to chase down a target of 166, including four off the last ball.

It was a frustration after such a dominant performance against Notts on Friday, although Derby look like they will challenge having won their first two.

Adam Lyth’s 68 off 54 balls at the top of the order represented his second successive half-century, but he fell in the penultimate over.

Derbyshire recovered from 48-4 to post 165-8, with Wayne Madsen top-scoring with 42 off 28.

In truth, the Falcons got more than they should have done, with 35 coming off the last three overs.

And a part of that was Yorkshire’s sloppy ground-fielding.

They did not drop a catch, but they let a couple of balls slip through their grasp, including a couple of early boundaries.

On Friday, Alex Hales was dropped on 30 in the deep. It looked like being costly, but Azeem Rafiq atoned for his error to dismiss him for 47.

“Against Notts, it was an outstanding performance,” said Moxon, Yorkshire’s director of cricket. “The batting was excellent throughout, and everybody clicked.

“This game, we weren't quite as fluent, and it was a slightly different pitch.

"We said on Friday the only slight blip was our fielding, and I think overall the difference was the fielding here. Derby made some outstanding saves, whereas we made some errors.

"You can look at overs here and there where we went for a few runs, but they did as well.

“I'm trying to summarise, and I think they out-fielded us.

“We've made too many errors, and in Twenty20 cricket you can't afford too many.”

This was only Yorkshire’s second ever away defeat to Derby in 12 T20 matches, both of which have come here in the last three seasons.

Madsen and New Zealand seamer Matt Henry gave the Falcons impetus from 48-4 in the ninth with a 57-run stand in 4.2 overs for the fifth wicket.

Henry hit Rafiq for two sixes and four in the eleventh over, taking 20 off it after the off-spinner had earlier taken two wickets.

Steve Patterson was Yorkshire’s standout bowler with 2-19 from four overs.

The Vikings chase got off to a bad start as Madsen’s part-time off-spin bowled Tom Kohler-Cadmore for a second-ball duck, but David Willey also hit 42 off 28 and shared 55 with Lyth.

Left-handed Lyth struggled to get out of the blocks like he had against Notts and was dropped on five and 30. But he managed to get going in the second half of the innings.

Unfortunately, South Africa leg-spinner Imran Tahir took 3-18 from four overs, including the key wickets of Willey, Peter Handscomb and Jack Leaning.

Yorkshire needed 47 off the last five overs and 18 off the last, by which time Lyth had holed out to long-off.

Seamer Henry bowled the last, and Tim Bresnan and Matt Waite got it down to five off the last ball, which became four following a wide.

Unfortunately, Bresnan holed out to cover as Yorkshire head into Tuesday’s clash with champions Northamptonshire at Wantage Road with a won one, lost one record.

Meanwhile, Moxon expects England limited overs seamer Liam Plunkett to be out for at least a total of five matches with a low grade groin strain.

* ADAM Lyth and Shaun Marsh starred with entertaining fifties as Yorkshire began their NatWest T20 Blast campaign with a record-breaking 48-run win over Nottinghamshire at Headingley on Friday.

The Vikings posted 227-5, their highest ever score in T20 cricket, before the Outlaws responded with 179-8.

Lyth hit 82 off 50 balls, including three of eleven sixes in the Vikings innings after they had opted to bat.

Marsh hit 60 not out off 37 with two sixes, and the pair shared 83 in 8.5 overs for the third wicket.

David Willey (25 off 13), Jack Leaning (17 off seven) and Peter Handscomb (21 off seven) all returned useful contributions.

England limited overs opener Alex Hales gave Yorkshire a scare with a fast start their chase. He hit 42 off the first 50 runs inside sixes overs and hit 47 off 26 balls in all.

Hales was dropped on 30 by Azeem Rafiq at deep square-leg before getting the key man caught at deep mid-wicket with his very first ball in the seventh over, leaving the score at 55-2.

Notts slipped to 84-4 in the eleventh over and failed to recover.

Rafiq finished with 2-38 from four and Rashid 1-22 from four in front of a 10,037 crowd – a Yorkshire home high outside a Roses match.
