It has been a campaign to forget for Ireland as they slipped to their fourth loss of the ICC Women s World T20 to end the tournament winless. And with that, curtains have also been drawn on careers of Cecelia and Isobel, the Joyce sisters, as the twins decided to retire from international cricket. <p></p> <p></p>As New Zealand women thumped Ireland by eight wickets to bag a consolation win, Cecelia and Isobel announced their decision to the team in the dressing room after the game during a team hurdle. This leaves Ireland women without four of their most prolific cricketers, as Clare Shillington and Ciara Metcalfe had already announced earlier that the Women s World T20 was going to be their last. <p></p> <p></p>In a career that began in July of 2001, Cecelia went on to play 57 ODIs and 43 T20Is for Ireland. In the 50-over format, Cecelia scored 1172 runs from 54 innings at an average of 23.44 with a highest of 78 not out. Her sister Isobel represented the country for the first time in 1999, and then played another 79 times in ODIs and on 55 occasions in T20Is, scoring 995 and 955 runs in the two formats respectively. Allrounder Isobel also picked up 33 T20I wickets. <p></p> <p></p>"I can't thank them enough for what they've done for us. The next 10-12 months will be about transitioning the team as we don't have any international fixtures coming up," Laura Delany, the Ireland captain, said.
