Mahela Jayawardene smashed a superb 98 as Sri Lanka defeated the West Indies by 57 runs in their Group F match of the World Twenty20 at the Kensington Oval here Friday.

Jayawardene's 56-ball innings was the centrepiece of the tournament's highest total of 195 for three. Jayawardene and Sri Lanka captain Kumar Sangakkara, who scored a 49-ball 68, shared a stand of 166 - the second highest in Twenty20 internationals surpassing the 170 put on by Loots Bosman and Graeme Smith for South Africa against England at Centurion last year.
