Hampshire suffered a dissapointing loss at the Kia Oval on Wednesday as Surrey raced to a seven-wicket win in the final away .
They secured victory with 15 balls to spare after restricting Hampshire to 133 for 7, with Aaron Finch leading them home with an unbeaten 67.
Hampshire's hopes had been briefly raised when Afghanistan off-spinner Mujeeb Ur Rahman bowled Jason Roy round his legs for a duck in the first over. Dale Steyn then deceived Will Jacks (7) with a slower ball to leave Surrey 25 for 2 in the fourth over.
But Finch, back in the side after missing three games because of a family bereavement, continued his outstanding form in the Blast, taking his competition aggregate to 545 runs.
He had a reprieve on 18 but otherwise Finch was untroubled as he and fellow Australian Nic Maddinson put on 92 for the third wicket in 11.4 overs.
Rahman picked up his second wicket when Maddinson (41) was stumped aiming to leg but Surrey only needed 17 to win and Finch saw them home, his runs coming off 57 balls with seven fours.
Earlier, after deciding to bat first, Hampshire had been becalmed by a slow pitch and some disciplined bowling and their total of 133 for 7, which contained two sixes and nine boundaries, was unlikely to test Surrey’s powerful batting.
They started promisingly. Rilee Rossouw (23) and Sam Northeast took them to 49 for 1 in the sixth over but after Rossouw upper-cut a slower ball from Morne Morkel to point Hampshire struggled to pick up momentum.
Northeast battled through to the 19th over to top score with 37 but his runs came off 36 deliveries and only contained one boundary and whenever Hampshire attempted to accelerate they invariably lost a wicket.
Dawson (17) briefly flourished before picking out short fine-leg trying to repeat a scoop off Morkel which had brought him a boundary from the previous ball. Captain Jade Dernbach picked up two wickets in the penultimate over and was the pick of the seamers with 2 for 19 while Batty also enjoyed the conditions, getting the ball to grip and turn as he took 1 for 18. Having been 77 for 2 at halfway, Hampshire only added 60 runs in the second half of their innings.
