Durban - The Sunfoil Dolphins enjoyed one of their best days of the season as they racked up 323 for three on the first day of their Sunfoil Series encounter against the Nashua Titans at Sahara Stadium Kingsmead on Thursday.Vaughn van Jaarsveld's sparkling 140 not out was the jewel in the crown for the home side, while opener Divan van Wyk fell eight, agonising runs short of what would have been an equally deserved ton, too.The Nashua Titans had won the toss and elected to bowl first, a decision that paid almost immediate dividends, when Imraan Khan was castled by Ethy Mbhalathi in the fifth over. From 12 for one, the Sunfoil Dolphins started their re-building in earnest, with Jonathan Vandiar (50) and Van Wyk adding 90 for the second wicket.Vandiar, cutting and driving with his customary ease, reached his half-century off 79 balls, but then fell just six balls later, caught by skipper Henry Davids off David Wiese for exactly 50.Van Jaarsveld then entered the fray, making his way to two before lunch, with Van Wyk holding firm on 38 not out.After lunch, the two southpaws upped the ante, with Van Jaarsveld going to a brutal half-century off just 47 balls, his knock studded by several, meaty blows to the fence. He also pulled Wiese over the square-leg boundary, as he hovered around a run-a-ball during the afternoon session.Van Wyk, steadily becoming a stalwart for the KZN franchise, reached his 50 with just his third boundary of the day, not that he was fazed by his deliberate pace. He was denied what would have been a stout ton when he was run out for 92, ending an imperious stand of 156 runs, which was put together in just under 40 overs.Van Jaarsveld, still playing his full range of strokes, reached his eleventh first-class ton, and carried on the onslaught, though he slowed somewhat towards the end of the day's play.Khaya Zondo played himself in and was sitting on 26 not out when stumps were drawn on a day that belonged to the Sunfoil Dolphins. Mbhalathi and Wiese took a wicket apiece for the weary Nashua Titans, and they will be bracing themselves for another tough day at the office on day two, with Van Jaarsveld holding the key for the hosts.
