West Indies 114 for 2 (Matthews 50, Henry 22*, Delany 1-12) beat Ireland 113 for 7 (Hunter 33, Fraser 1-16) by eight wickets
"I think we're pretty happy with the result," Matthews was quoted as saying by Cricket West Indies after the match. "Coming into this tour, we wanted to be able to take home both series [West Indies won the ODIs 2-0], so just very happy that we were able to go out there and win convincingly today and secure the T20I series.
"We had more intent going out today and we noticed early on that the wicket was a bit better on today and we went out with the intent to chase down the runs quicker. What really helped us today was the fielding, the catches and run-outs we were able to take, kudos to the overall team for the bowling performance they put on and the fielders for backing them up."
Indeed, more than Matthews or any of the other West Indies bowlers - Shamilia Connell and Cherry-Ann Fraser took one wicket each, too - it was the run-outs that stymied Ireland after they had opted to bat. The first wicket, that of Gaby Lewis, was to a run-out, and the collapse from 77 for 3 in the 16th over to 113 for 7 by the end featured three more run-outs.
Matthews lost her opening partner Rashada Williams (16 in 20) off the first ball of the seventh over after a 40-run stand, which put them on the road to victory. And after Matthews fell, Henry and Gajnabi took West Indies home with lots to spare.
The tour-ending third T20I will be played on July 8, also in Gros Islet.
