Zunaed Siddique and Mashrafe Mortaza scripted Bangladesh's first-ever victory over New Zealand in one-day cricket with a comfortable seven-wicket win in the opening match on Thursday. Left-hander Siddique scored a brilliant 85 for his maiden half-century to anchor his team's successful chase of a 202-run target in 45.3 overs at Shere Bangla National Stadium after paceman Mortaza took 4-44 to jolt the tourists.
