Sri Lanka's Kaushal Silva and Kumar Sangakkara offered stubborn resistance on the second day of the opening cricket Test at Lord's after Joe Root put England in control by hitting his maiden Test double ton.
The 23-year-old Root, dropped for the final Ashes Test during England's 5-0 whitewash Down Under, brought up his 200 with a dab behind square after a well compiled innings that featured 16 boundaries from 298 balls.
Alastair Cook immediately declared the innings on 575 for nine once Root had reached his milestone, leaving Sri Lanka openers Silva and Dimuth Karunaratne to negotiate a tricky spell before tea.
Karunaratne, who successfully overturned an lbw appeal off James Anderson in the first over and offered a chance to the slips soon after, fell to Chris Jordan's third ball in test cricket when on 38, edging to Prior behind the stumps.
However Silva (62) and Sangakkara (32) battled their way through to 140 for one at the close, although the former was lucky to survive a caught behind appeal off Stuart Broad on his way to his fourth half-century, with the third umpire ruling Prior had not claimed the catch cleanly.
