Hobart, Oct 21 : Leg-spinner Gareth Delany picked career-best figures of 3/16 while veteran opener Paul Stirling, playing in his seventh Men's T20 World Cup, stood up when it mattered the most, slamming a sensational 66 not out to take Ireland to the Super 12 stage of the ongoing tournament with a nine-wicket drubbing of West Indies in a decisive Group B match of the first round at Bellerive Oval on Friday. After Delany kept things tight, with other bowlers chipping in, to keep the West Indies to an under-par 146/5 in 20 overs, with Brandon King making an unbeaten 62, Stirling came out all guns blazing in his unbeaten 48-ball knock, hitting six fours and two sixes to make a mockery of the chase, hunting down the total with 15 balls remaining. He stitched a blazing 73-run opening stand with captain Andrew Balbirnie and then put on 77 runs for the unbroken second-wicket stand with Lorcan Tucker (45 not out) for Ireland to enter the Super 12 stage after failing to get past the first round in their last five T20 World Cup appearances and knock out the clueless two-time champions out of the competition. After getting off the mark with a top-edge flying over slip off Obed McCoy in the opening over, Stirling fiercely swept Akeal Hosein for four while Balbirnie swept the left-arm spinner for six to take 16 runs off the second over. While Stirling powerfully clobbered Alzarri Joseph for six over deep mid-wicket, Balbirnie upped the temp by hitting two fours and a six on the first three balls of Odean Smith. He then brought up the fifty of the opening partnership with an inside-out loft over cover-point for six. Stirling continued to feast on Joseph in the final over of power-play -- a top-edge flew over vacant slip cordon and on the very next ball, sliced through backward point to make it back-to-back fours. After Balbirnie fell while cutting hard to a diving backward point off Hosein, Stirling ensured Ireland didn't lose their way by dispatching Joseph for a six over deep square leg and got his 21st T20I fifty by placing a late dab past third man for four. He found an able ally in Tucker, who survived a caught-behind appeal off Smith on a no-ball. After getting off the mark with a sweep off Hosein, Tucker went one step further by slog-sweeping him for six and brought up fifty of his second wicket stand with Stirling with an authoritative six over long-on for six off McCoy. Stirling gave a glimpse of his innovative stroke-play, moving across and scooping Joseph over short fine leg for four. Tucker finished off the chase in style, dancing down the pitch and converting a half-volley from McCoy into a loft over cover for four to give Ireland the ticket to Super 12. Earlier, pushed into bowling first, Ireland drew first blood as Barry McCarthy foxed Kyle Mayers with his length ball, the left-hander completely mistiming the ball to mid-off. Johnson Charles feasted on Curtis Campher's short balls, taking two fours and a six on three consecutive deliveries in the fourth over. But just he was starting to take off, off-spinner Simi Singh took him out in his first over, as Charles sliced a short ball straight to backward point. King, coming into the playing eleven in place of Shamrah Brooks, was off the mark on the very first ball with a drive past mid-off off Singh. He then got going with three fours off the bowling of McCarthy and an off-colour Campher. But he didn't find much support from the other end as Evin Lewis was rusty in his 18-ball stay and departed when he miscued a Delany googly to deep mid-off. King continued to anchor the innings with back-to-back fours off McCarthy and get his sixth T20I fifty even as captain Nicholas Pooran fell while trying to clear the infield and Rovman Powell holed out to deep mid-wicket. With King unable to get the desired acceleration, Smith swung hard to hit a four and two sixes in his 19 not out off 12 balls, but was unable to push West Indies past 150-mark. Brief scores: West Indies 146/5 in 20 overs (Brandon King 62 not out, Johnson Charles 24; Gareth Delany 3/16, Simi Singh 1/11) lost to Ireland 150/1 in 17.3 overs (Paul Stirling 66 not out, Lorcan Tucker 45 not out; Akeal Hosein 1/38) by nine wickets. /IANS
