Joe Root top-scored with 49 off 36 balls as he captained Yorkshire to a 39-run Vitality Blast win over Derbyshire Falcons at Emerald Headingley.

The England Test captain is back in Vikings colours prior to one-day international duty next week and contributed significantly, alongside Harry Brook’s unbeaten 48, to their 174 for six having been inserted.

Seamer George Scrimshaw claimed a career best three for 30 for the Falcons, who then fell well short of their target at 135 all out in 19 overs.

Dom Bess and Lockie Ferguson finished with three for 21 apiece as Yorkshire claimed a fourth win in six North Group games to move top of the group at time of victory. Derbyshire suffered their fifth defeat in seven.

Root missed out on a sixth half-century in his last seven Blast innings dating back to July 2018. But he still averages a fabulous 75.59 with 378 runs in that sequence.

He came into Yorkshire’s team as one of four changes from last Wednesday’s win at Worcestershire - Friday’s clash with Birmingham was rained off - with Jonny Bairstow, Dawid Malan, Adil Rashid and regular skipper David Willey all on T20 international duty.

Root was in after five balls of the game and navigated his side away from danger at eight for one and later 56 for three in the eighth over on a true pitch.

Typically busy, he shared 57 in six overs for the fourth wicket with Brook before being caught at mid-on off impressive Scrimshaw, who also removed Gary Ballance and Will Fraine.

Jordan Thompson twice, Brook and Matthew Waite shared four sixes in the last nine balls of the innings to boost Yorkshire’s total.

And Root, captaining his county for the first time in a limited overs game, struck 10 balls into Derbyshire’s chase when Luis Reece skewed his off-spin high to point - three for one.

New Zealand overseas quick Lockie Ferguson and seamer Matthew Waite also struck in their first overs to remove Harry Came and Billy Godleman.

And when Bess claimed a sharp return catch to remove Leus du Plooy, Derbyshire were in deep trouble at 49 for four after nine overs.

That was the outstanding moment of the fixture as the England Test spinner tumbled away to his right to complete the catch.

Bess had Matt Critchley caught at long-on and Brook Guest caught at long-off to secure career best figures in only his 10th T20 appearance - 84 for six in the 14th.

Fynn Hudson-Prentice hit 34 and Alex Thomson 28, but they only added respectability before falling to successive Thompson deliveries in the 18th over - 126 for eight.

Ferguson then cleaned up the tail in the penultimate.

Yorkshire face 2018 champions Worcestershire Rapids at Headingley on Wednesday evening (6.30pm).

They will be hoping to repeat last week’s 94-run success at New Road when they racked up 216 for six and comfortably defended it.

It marks the halfway point in the competition for the Vikings, and it will be their fifth home fixture of the campaign.

The plan is for Root to be available for the next two or three North Group matches ahead of the start of England’s ODI series against Sri Lanka at the end of the month.

Dom Bess said: “I haven’t played a lot of first-team T20. When I was at Somerset, it was mostly in the second team.

“It’s nice to get the opportunity and contribute to a really strong win. It was great fun. There’s still a long way to go. It’s really important we keep this momentum going.”
