Tom Curran followed in brother Sam's footsteps by leading England's attack as Sri Lanka were dismissed for just 166 in the third one-day international at Bristol on Sunday.

The older of the two Currans in the England XI, Tom took 4-35 in his maximum 10 overs.

That followed Sam's return of 5-48 during an eight-wicket win at the Oval -- the brothers' Surrey home ground -- on Thursday that put the hosts an unassailable 2-0 up in this three-match series.

Tom's wickets represented the right-arm paceman's first for England in six white-ball appearances. He had previously bowled 34 overs in T20s and ODIs without success.

Only Dasun Shanaka, with a 48 not out that included a fine straight six off leg-spinner Adil Rashid, offered significant resistance with the bat.

Sri Lanka's top order have struggled during the past fortnight, repeatedly losing wickets to the new ball.

And it was an all-too familiar story at the County Ground as they suffered another collapse to 63-5 inside 15 overs after losing the toss as Chris Woakes and David Willey made early inroads.

Woakes, the only change to the England side, struck in his second over when he had Sri Lanka captain Kusal Perera chopping into his stumps for nine.

Willey took the new ball ahead of Sam Curran, despite his fellow left-arm swing bowler's success at the Oval, and, after conceding 17 runs in his first two overs, had Aviskha Fernando lbw on review.  

When Willey had Pathum Nissanka caught behind, Sri Lanka were 33-3.

Dhananjaya de Silva, who made a fine 91 at the Oval, then fell for just four when a miscued hook off Woakes was caught by Rashid at fine leg -- the latest example of a Sri Lanka batsman falling to the short ball.

Oshada Fernando then chipped Tom Curran, at 26 three years older than Sam, to Woakes at mid-off.

Wanindu Hasaranga had made 20 when a pull off Tom Curran lobbed gently to Willey, jogging in from deep square leg to leave Sri Lanka 87-6.

There was a brief respite until Chamika Karunaratne was well caught by Bairstow, diving to his right, to give Tom Curran his third wicket.

Sri Lanka's running between the wickets has been poor all tour and the innings ended with nearly nine overs to spare when Asitha Fernando was run out after a huge mix-up with Shanaka. 

England bowl against Sri Lanka in third ODI

England captain Eoin Morgan won the toss and elected to field in the third one-day international against Sri Lanka at Bristol on Sunday as the hosts eyed a 3-0 series  sweep. 

Despite leading 2-0 in the series, after wins at Chester-le-Street and the Oval, England resisted the temptation to give left-arm quick George Garton a debut or recall batsman Tom Banton or spinner Liam Dawson.

Instead, they made just the one change, with pace-bowling all-rounder Chris Woakes replacing fellow World Cup-winner Mark Wood.

Sri Lanka also made one change, with Oshada Fernando replacing Charith Asalanka.

With rain delaying the toss by a few minutes, Morgan said his decision to field was partly influenced by bad weather.

As for, fielding a largely unchanged team, the captain added: "There's always a temptation to look at young guys. Tom (Banton) has played for us before and George (Garton) is new to the squad, so every time we look at selection we do keep an eye on the long-term plan for that player.

"So we don't necessarily want to chuck them in a one-off game that has little context, we'd rather them be around the squad and start to feel more comfortable and then introduce them when opportunities present themselves."

Sri Lanka's batting has been their weakness in both this series and a preceding T20 campaign loss to England. 

"We are expecting swing and bounce but we need a positive approach but follow the basics too," said Sri Lanka captain Kusal Perera.
