Mendis 87 leads Sri Lanka's batting charge on day one

Stumps Sri Lanka 305 for 6 (Mendis 87, Karunaratne 50, Southee 3-44) vs New ZealandImpressive knocks from almost the entirety of the Sri Lankan top order, particularly Kusal Mendis, gave Sri Lanka a promising start in their pursuit of an unlikely World Test Championship final berth, as they put up 305 for 6 on the opening day of the first Test at Hagley Oval.

Henry and Neil Wagner were punished as they looked to test the diminutive Lankan with some short stuff, while Southee and Blair Tickner were whipped in front of square for deliveries that veered a little too full or straight.There were a few dicey cuts over gully as well, but Mendis' only genuine moment of peril came when he was yet to get off the mark.
