Graeme van Buuren posted his first Gloucestershire List-A hundred to guide his team to a hard-fought 23-run victory over Northants Steelbacks in the Metro Bank One-Day Cup at Cheltenham.Returning after a month recovering from injury, the South African top-scored with a pugnacious 108 and helped stage a stand of 104 with Anwar Ali for the eighth wicket as the home side recovered from 142 for 7 to make 278 in 48.4 overs.Recruited on a short-term overseas contract, Anwar weighed in with an entertaining 61 to redress the balance after seamer Ben Sanderson had claimed three wickets in 13 balls to make a mess of Gloucestershire’s top order.Ajeet Singh Dale then returned figures of 4 for 58, including a burst of three wickets in 11 deliveries, and Tom Price took 4 for 26 as Steelbacks, who never recovered from the wreckage of 30 for 5 in the tenth, were eventually dismissed for 255 in 48.1 overs. Tom Taylor at least put up a fight, making a valiant effort to turn the tide in a combative innings of 112 from 87 balls, while skipper Lewis McManus contributed 54 to put Gloucestershire celebrations on hold.Signing off from the Festival in style, Gloucestershire have now won their opening two games in the 50-over competition to lay down a marker at the top of Group B.A large College Ground audience of 4,000 roared their approval as Singh Dale and Price cooked up a storm with the new ball, five of Northamptonshire’s top six batsmen failing to make double figures as the reply ran into immediate trouble. Price had Emilio Gay caught at mid-on and then bowled Ricardo Vasconcelos in his next over from the College Lawn End to set nerves jangling in the away dressing room.Singh Dale bowled Sam Whiteman and Luke Procter with the last two deliveries of the sixth over and, although Rob Keogh survived the hat-trick ball, he did not last long thereafter, edging a catch behind to spark pandemonium in the marquees.Only new overseas signing Prithvi Shaw proved immune to the chaos all around him, the Mumbai batsman standing firm and hooking Singh Dale backward of square for a towering six to demonstrate his defiance. But not even he was up to a task of this magnitude, and he eventually perished for 33, attempting to hook Paul van Meekeren and conspiring to hit his wicket.
