SURREY put a significant dent in Glamorgan's hopes of reaching the quarter finals of the NatWest T20 Blast with a 19-run victory at the Swalec Stadium, writes Graham Clutton.

Having come into the game, glued to the foot of the South Group, Surrey not only won for only the second time in the competition this season, but left Glamorgan to lament a second successive home defeat and a fifth in nine games.

Batting first, Surrey made a decent start courtesy of England opener Jason Roy and South African Dean Elgar. Without ever cutting loose, on a difficult surface, they added 76 for the first wicket before the latter holed out to David Lloyd off Andrew Salter in the 10th over.

Thereafter, the early evening belonged to Glamorgan and evergreen spinner Dean Cosker. The 37-year-old left armer returned career best T20 figures of 4-25, off four overs, as Surrey went from 104-1 in the 14th over, to 146-8.

Roy, who hit three fours and as many sixes in a 39-ball half century, top scored with 61, but when he became Cosker's key scalp, at 104-2, Surrey capitulated.

Cosker sent back Gary Wilson, Azhar Mahmood and Ben Foakes, as the visitors lost their way and Colin Ingram returned to pick up the vital wickets of Vikram Solanki and James Burke.

Having reverse swept the first ball he faced for a boundary four, Jacques Rudolph became Glamorgan's first man out – caught behind by Wilson off an unplayable delivery from Azhar Mahmood.

Craig Meschede took up the challenge, thereafter, and dispatched Tim Linley for 18 in four balls, including a six over long on. However, the Somerset loanee lost partner Ingram at 41-2, off the final ball of the fourth over and then, played his part in the unfortunate dismissal of Chris Cooke, 11 balls later.

Having struck a firm drive back towards James Burke, he could scarcely believe his misfortune as the bowler deflected the ball onto the stumps, at the non-strikers' end, with Cooke stranded out of his crease.

An over later and Glamorgan were staring down the barrel of another disappointing reverse in front of a crowd of well over 6000. In-form Graham Wagg edged the impressive Mahmood to Wilson, at 45-4 , and then, off the final ball of the over, Meschede was trapped lbw for 31. Mahmood finished with 3-14 off four overs.

Mark Wallace and David Lloyd provided temporary respite, but when Elgar was introduced at the River End, Glamorgan lost their sixth wicket, at 60. Lloyd, having reached seven, misjudged a sweep and was trapped leg before by the 28-year-old slow left armer.

Wayne Parnell produced one or two fireworks, but when Wallace picked out Roy at deep mid wicket, at 94-7, Glamorgan were heading towards a fifth T20 loss of the summer. They eventually fell 20 runs short of their target, reaching 127 all out, with Andrew Salter unbeaten on 17.
