Colin Munro produced a vintage show at FTZ grounds Katunayake ahead of the three-match T20I series against Sri Lanka, hitting 48 off 27 balls and having to retire as New Zealand won their warm-up T20 match against Sri Lanka Cricket President’s XI by 33 runs yesterday.New Zealand batting first totalled 168-6 and restricted the SLC President’s XI to 135-9.Munro’s was the first wicket to fall, but by then, he’d been responsible for nearly 70% of the New Zealanders’ total and had put them comfortably ahead of the game. That luxury eventually proved a necessity because, having opted to bat, the visitors slipped from 69 for 0 to 84 for 3 as legspinner Wanindu Hasaranga gave them a reminder of the kind of problems they will face when the T20I series begins in Pallekele on Sunday.
