Surrey 155 for 3 (Stoneman 53) beat Glamorgan 152 for 6 (Ingram 41) by seven wickets
Glamorgan's abysmal season in the T20 Blast continued at Sophia Gardens where they were beaten by Surrey with six balls of an entertaining game remaining. The home team were some 30 runs short of a competitive total, with their top order batsmen - apart from Colin Ingram - again failing to lay foundations.
Despite losing Aaron Finch in the first over, the other batsmen contributed for Surrey, Man-of-the-Match Mark Stoneman top-scoring with 53. Surrey moved on to five points, some way adrift of the qualification spots, while Glamorgan remain bottom without a win in this season's competition.
With Surrey needing to score at seven-and-a-half runs an over, Ruaidhri Smith, playing his first Blast game of the season after injury, gave Glamorgan the perfect start by dismissing the dangerous Finch with the final ball of the opening over.
Will Jacks and Stoneman soon settled, however, with Jacks the more aggressive, and the second-wicket pair had taken Surrey to 70 for 1 by the halfway stage. After adding 82, Jacks then surrendered his wicket by edging to the wicketkeeper from a wild heave.
Stoneman was the next to go, caught on the long-on boundary after scoring 53 from 49 balls, with Smith taking his third wicket. Surrey required a further 46 from the remaining five overs, then 19 from two, but de Lange was struck for 21 by Ollie Pope and Ben Foakes to secure victory, Pope finishing things with his second six.
Glamorgan, who were put in, were soon in trouble, stumbling to 34 for 3 in the 6th over, which included the wicket of Australian batsman Shaun Marsh, playing his first game since breaking his arm during the World Cup. Marsh was out third ball, giving Imran Tahir a return catch, then the club's second overseas player Fakhar Zaman, who has contributed only 100 runs from six innings at an average of 16, poked a simple catch to short third man.
Much depended on Ingram and Chris Cooke. After adding 27, Cooke, who had been dropped earlier in his innings, holed out on the mid wicket boundary. Surrey's fielding was sloppy throughout with Finch letting a ball go through his legs for four, with others dropping three catches.
Ingram, who has also experienced a disappointing tournament by his standards, revived the innings by scoring 41 from 33 balls, which included two sixes, but with 5.3 with overs remaining Ingram was deceived by Tahir, giving Foakes a simple stumping.
Glamorgan were indebted to Dan Douthwaite and Graham Wagg at the end of the innings - Wagg striking three sixes in his unbeaten 36 - but the total still turned out to be below par.
