West Indies have secured the series after their back-to-back wins in Trinidad, one a last-ball thriller and the other a more comfortable success completed by the man-of-the-moment, Shivnarine Chanderpaul, and Marlon Samuels. It has been an uplifting couple of weeks for West Indies, following their series-levelling Test victory, and a whitewash of the one-dayers would set them up nicely for the ultimate challenge of facing Australia. For Sri Lanka it's about salvaging pride from a tour that started so promisingly before fading away. They have clearly missed some of their experienced players, but no one ever said rebuilding a side would be easy.
Form guide - West Indies
Last five matches: LLLWW
Player to watch: It hadn't been a happy home season for Marlon Samuels until Saturday's match-winning 54 off 49 balls. He seems to have been weighed down by the controversy over his bowling action, but showed a timely return to form in Trinidad. He has always been a batsman of immense talent and maybe forgetting about bowling completely is the way for him to go.
Form guide - Sri Lanka
Last five matches: LLWLL
Player to watch Chamara Kapugedera rescued Sri Lanka in the first ODI with a career-best 95 but didn't get a bat in the following game. Kaushalya Weeraratne was promoted to No. 4 as a pinch-hitter - and laboured to 15 off 20 balls - while Kapugedera kicked around the changing rooms. If Sri Lanka want to change their order he may as well be given a chance higher up to make the most of his form.
West Indies had a stronger bowling attack for the second match in Trinidad after drafting in Daren Powell who should keep his place. Darren Sammy could come under pressure if they decide to recall Sulieman Benn, the left-arm spinner, on what is usually a batsman-friendly surface.
Sri Lanka could decide to give some of their other squad players an outing. In the other matches two bowlers have been off the pace so Thilan Thushara, who impressed in the Test series, would provide a striking option. Chaminda Vaas may have earned a rest at the end of the tour.
West Indies (probable) Chris Gayle, Sewnarine Chattergoon, Ramnaresh Sarwan, Marlon Samuels, Shivnarine Chanderpaul, Dwayne Bravo, Denesh Ramdin (wk), Darren Sammy, Jerome Taylor, Daren Powell, Fidel Edwards
Sri Lanka (probable) Upul Tharanga, Mahela Udawatte, Kumar Sangakkara (wk), Mahela Jayawardene (capt), Tillakaratne Dilshan, Chamara Silva, Chamara Kapugedera, Nuwan Kulasekara, Chaminda Vaas, Ajantha Mendis, Thilan Thushara
Pitch and conditions
The St Lucia pitch is usually good for batting and 250 is the minimum a team needs to defend. With this being a day/night game the teams will have to adjust their tactics accordingly, although there is limited evidence as to the effect of the lights. The only other floodlit match finished with more than 22 overs to spare as a 10-wicket win for West Indies. There is a chance of showers during the game, so once again Duckworth-Lewis could play a role.
Stats and trivia

"Our group of guys has been working hard for some time and I'm really pleased for them that they've been able to put it together in front of their home crowd."
