Team Vince 109 for 4 (Banton 57*) beat Team Moeen 108 (Dawson 4-21, Gregory 3-29) by six wickets
Tom Banton showed his class in the field and with the bat after Lewis Gregory and Liam Dawson shone with the ball in England's second intra-squad match ahead of the start of their one-day series against Ireland.
Gregory snared Jonny Bairstow - following a sublime catch by Banton - en route to 3 for 29 while Dawson subdued the lower order in his 4 for 21 as a side led by Moeen Ali succumbed to a meagre 108 all out in 28.4 overs.
England captain Eoin Morgan was rested so James Vince led the other team, who slipped to 4 for 3 after eight balls of their chase, but Banton ushered them home with six wickets to spare in 17.4 overs with a stylish 57 not out from 56 deliveries at the Ageas Bowl, the venue of the ODI series which gets under way next Thursday.
Jason Roy was also absent from an encounter that was once again supposed to be 40 overs a side as he was nursing a sore back, but he and Morgan are set to feature for England Lions in Sunday's game against Ireland.
While Tuesday's first warm-up was a boundary-laden affair in which Bairstow and Moeen teed off with abandon, a more sluggish surface here was exploited by some clever bowling allied with some injudicious strokeplay.
With Phil Salt and Sam Hain failing to get out of single figures, attention fell on to Bairstow again. A centurion a few days ago, the Yorkshireman could not get into his groove and departed for 13 off 21 balls following a supreme catch from Banton diving full length to his right at backward point.
That handed Gregory a wicket in his first over and he would have two in two when Liam Livingstone shaped to run down to third man only to chop on. While Moeen nudged and nurdled his way to 17, his attempt to inject more urgency into proceedings fell flat as he charged down the wicket to Gregory and top-edged to long leg.
Salt was given another opportunity at the crease and clubbed Dawson for the first six of the innings over midwicket, but when going for another big mow he merely edged to slip for 25 off 37 balls.
From there, spin duo Dawson, on his home ground, and Adil Rashid squeezed the life out of the lower order, the former bowling Brydon Carse and Tom Curran, both attempting to cut, before trapping Saqib Mahmood in front to end the innings with 11.2 overs unused.
If there was any thought of a comfortable chase, it was snuffed out when David Willey gained a fraction of inward movement to bowl Ben Duckett and Sam Billings with the first two balls of the reply, before Vince departed in the next over after being adjudged lbw to Tom Curran.
But Banton and Laurie Evans rebuilt, slowly at first, the former taking the whip hand with crunching fours through the covers off Willey. Evans was happy to play the auxiliary role but still managed around a run a ball.
Willey could not cling on to a chance at deep midwicket that would have rivalled Banton's earlier grab as the batsman was spared on 32, and thereafter he put his foot down, emphasised when he swivel pulled Mahmood for six.
Evans chopped Henry Brookes on to his stumps for 25 to end a 67-run stand but it was of little consequence as Banton passed his 50 before Dawson sealed the win with two fours in three balls in the late evening sunshine.
