Ross Taylor is glad his Sussex side are still in the top-four hunt.

But Sharks will need a favour from elsewhere if they are to reach the next stage of the NatWest T20 Blast.

Sharks went down by 17 runs to Surrey before a crowd of 13,229 at the Kia Oval.

Aaron Finch’s brutal 114 put the hosts out of sight and kept their own qualification hopes alive.

Sussex must beat Essex at Hove on Friday to have any chance of squeezing into the last four while Surrey will probably need to win both their remaining games.

Both are among five counties locked on 12 points in the table.

Sharks skipper Taylor said: “We’re still in with a shout of reaching the quarter-finals.

“A couple of results might have to go our way but going into the last game to still be in the hunt shows just how good a competition it’s been.

“Hopefully we can get the right result against Essex on Friday.

“You have to give credit to Aaron Finch who batted outstandingly well.

“If you look at the whole match it was pretty even until the 16th over but overs 18-20 were very big for Finch and from then the momentum was very much with Surrey.”

Finch equalled the Surrey record of seven sixes in a T20 innings held by Mark Ramprakash, striking four of them in a remarkable assault on David Wiese in the 18th over.

He cleared the ropes off four successive deliveries – two over mid-wicket and two over long-off – before hitting the last ball for four in an over which yielded 30 runs and transformed the Surrey innings.

Finch and Jason Roy, whose 50 was his highest score in this season’s Blast, had posted 91 in the first ten overs, but Surrey only added 31 in the next five as Chris Jordan, whose four overs cost just 19 runs, and leg-spinner Will Beer dragged Sussex back into contention.

Then Finch launched his withering assault on Wiese as Surrey plundered 71 off the last five overs.

A target of 194 was always going to be tough to get on a pitch already used twice this summer during the Champions Trophy but Chris Nash kept Sussex’s hopes alive with his fifth half-century in this season’s Blast.

The opener struck 53 off 38 balls, with five fours and two sixes, but after he was caught on the long-on boundary in the 14th over Sussex’s chase fizzled out, although Jordan and Jofra Archer added an unbeaten 39 at the end.

Nash played well without being able to match Finch’s power and while he and Stiaan van Zyl were adding 48 in 29 balls for the second wicket Sussex had a chance.

But van Zyl was caught at deep mid-wicket for 29 off Gareth Batty’s first ball and it turned into a profitable afternoon for Surrey’s captain.

Batty bowled his left-arm spin adroitly and took key wickets of Nash, Taylor, whose 11 continued a disappointing run of scores, and Laurie Evans.
