Dilshan Madushanka, Dunith Wellalage and Sahan Arachchige are set to link up with the senior squad on June 23, after Sri Lanka Cricket announced that the trio would be flown in to Zimbabwe for the World Cup Qualifiers as “standby options”.The inclusion of Madushanka, a left-armer able to swing the ball at pace, follows impressive recent outings against South Africa A, where he picked up nine wickets across three 50-over games and then another four in a four-day encounter, and comes on the back of him becoming the most expensive signing at $92,000 at the inaugural LPL auction. It also makes sense considering the fragility of Sri Lanka’s seamers. Lahiru Kumara has a recent history of breaking down mid-game, while Dushmantha Chameera’s work load is being carefully managed. This leaves just Kasun Rajitha and the raw Matheesha Pathirana as reliable seam-bowling options.In Wellalage, meanwhile, Sri Lanka cover several bases, with the Under-19 captain a capable left-arm spinner – an option currently missing in the squad – while also offering an extra batting option lower down the order. He is also one of the better fielders in the Lankan setup.As for Arachchige, he was another that sparked a bidding war at the LPL auction, eventually being sold for $28,000. It was an impressive fee for a player that has yet to make his debut for the national side, but the aggressive 27-year-old is highly rated, has recent performances in the bank – three fifties in his last five one-dayers, including two against South Africa A – and looks on the cusp of making the step-up to the international stage.Sri Lanka won their opening game in the World Cup Qualifier against UAE by 175 runs. They next play Oman on June 23 in Bulawayo.
