Rain may have cut short yesterday's third One-Day International (ODI) between England and Sri Lanka but for Liam Plunkett, there was the satisfaction of taking his 50th wicket at this level - more than a decade after his first.
England's Jason Roy scored 162 to give his side a series-clinching six-wicket win over Sri Lanka in the fourth one-day worldwide.
The only lingering concern for England is Hales' fitness, and Morgan hinted he may be a doubt to face Sri Lanka again at the weekend.
England's easy victory came after Sri Lanka had provided its best batting performance of the series, with Danushka Gunathilaka, Kusal Mendis, Dinesh Chandimal and Mathews all making half-centuries after the Sri Lankans were put in to bat.
Kusal Mendis, Danushka Gunathilake, Dinesh Chandimal and captain Angelo Matthews all smashed half centuries as Sri Lanka made 305-5 in a rain-hit fourth one-day worldwide at The Oval on Wednesday.
England are hoping for an opportunity to rediscover stalled momentum in the Royal London Series at The Oval.
Sadly for Roy he fell just five runs short of overtaking the highest score by an England batsman with Robin Smith's 167 not out against Australia at Edgbaston in 1993 still holding firm.
It led England to 308, their second-highest successful ODI chase, with 11 balls to spare in a match reduced to 42 overs because of rain at The Oval.
England's target was revised up by just three runs but with Roy building up a full head of steam they cruised home comfortably. Dinesh Chandimal, Upul Tharanga and skipper Angelo Mathews aside, Sri Lanka were bad both with the bat and on the field.
The bowling department of Sri Lanka rarely looked settled especially in the second ODI where they hardly found their line and length and allowed the Hales and Roy to chased the target easily without losing a single wicket.
Sri Lanka captain Angelo Mathews: "I thought we had a good score on the board".
And they clinched the series 2-0 with just one game left in Cardiff on Saturday. I'll take second and a series win - that's pretty cool to me.
A minimum of 20 overs needed to be bowled in the second innings for a result to be declared under the Duckworth/Lewis method for rain-affected matches.
"I'll probably still want to play Test cricket when I'm 38". The opener hardly put a foot wrong and ensured England kept up with the required run rate.
The all-rounder has impressed in the series so far, Sunday's effort coming on the back of figures of 0-36 at Edgbaston and a crucial unbeaten 95 to secure England an unlikely tie in the opening contest.
