Both of these sides are at the wrong end of League One but at the current odds, the home side look the better bet in Sunday's live lunchtime game.
Coventry have struggled on their return to the third tier, and they have been particularly poor away from home. The Sky Blues have only scored once in three games on the road in League One, and that makes them hard to back here.
Karl Robinson's Oxford are a limited side, but as Alan Dudman points out in his must-read League One Preview, they have suffered significant injury problems in the opening weeks of the campaign, and have also shown signs of improvement recently, beating Burton, then earning a point at the Stadium of Light. A repetition of that level of performance should be enough to see off Coventry this weekend.
Guyana have never won the Caribbean Premier League but they've never finished worse than third, and they're looking good for a play-off spot once again this year.
The Amazons have two games in hand on second-placed St Kitts and Nevis, who have played all of their Group games. That gives Guyana two bites of the cherry to snatch second and avoid the sudden-death Eliminator, and with their final game coming against leaders Trinbago, Sunday's match is their best chance of a win.
Jamaica are not a bad side but they've lost four of their last six and their bowling unit has struggled to contain most of their opponents. By contrast, Guyana have been economical with the ball, led by Imran Tahir, who has taken 13 wickets with an economy rate of 6.03. Back Guyana to stifle Jamaica and claim second spot.

Sale lost their opening Premiership match against Harlequins but Sunday's match looks a much easier task. Worcester won only twice on the road last season and haven't won at Sale since 2008, losing eight of their last nine against the Sharks.
The home side will be keen to pick up early points as they try to improve on last season's eighth-placed finish and they have a strong home record, their only defeats in their last seven at AJ Bell Stadium coming against Saracens and Leicester. Back Steve Diamond's side to pick up their first win of the season.
