|NatWest T20 Blast, Kia Oval|
|Surrey 137-7 (19.1ovs) beat Somerset 136-9 (20ovs) by three wickets|
Kevin Pietersen's highest score of the domestic season helped Surrey to a three-wicket win over Somerset.
The visitors made a positive start, with Nick Compton reaching 20 and Peter Trego hitting 30 off 23 balls.
But from 72-2 in the ninth over, Somerset could only post 136-9 as Matt Dunn took 3-9 in two overs.
Pietersen led Surrey's chase with 39 from 28 balls and, after a mid-order wobble, Zafar Ansari hit the winning runs with five balls to spare.
Surrey move up to second in the South Group table, four points behind leaders Essex, while Somerset remain fifth, two points behind fourth-placed Glamorgan.
After Jason Roy fell to Dirk Nannes (2-28) for four, Pietersen and Tillakaratne Dilshan (29) put on 66 for the second wicket.
But both fell in successive overs as Dilshan was caught by Trego off Nannes, while Max Waller (2-24) got Pietersen to chop onto his stumps when trying to cut.
Wickets continued to fall and the large Oval crowd were kept entertained, with 23 needed from 18 balls.
Twelve off Craig Overton's over reduced the target, before James Hildreth took a great catch in the deep off Alfonso Thomas to get rid of Azhar Mahmood (13).
But Ansari held his nerve to secure Surrey's seventh win of the T20 campaign.
