WI vs SL: Fabian Allen Leads Windies To 3-Wicket Win, T20I Series Triumph Over Sri Lanka

"I prepare for everything, including bowling in the powerplay," said Allen, who earlier took 1-13 opening the bowling.

"When I look in the dressing room we have a lot of batting power.

"I told (batting partner) Jason Holder that I'm not comfortable batting against (Wanindu) Hasaranga, so I told him to bat him out and I'll be finishing. I just backed myself in the end. It was a good performance overall."

The home side were cruising after limiting Sri Lanka to 131-4.

Openers Evin Lewis (21) and Lendl Simmons (26) gave them a solid start before Sri Lanka leg spinner Hasaranga (2-13) dismissed them both for a series haul of eight wickets.

Wrist spinner Lakshan Sandakan clean-bowled Gayle for 13, completing a poor international return for the 41-year-old who made just nought and 16 in the first two games.
