Greg Maybury, the Somerset fast bowler, remains doubtful for his team’s crucial Premier Division Twenty20 clash with St David’s at Somerset Cricket Club tomorrow.The experienced new ball bowler has been plagued by a knee injury which will be assessed during a fitness test on the eve of tomorrow’s intriguing match-up to determine his availability.“Greg will more than likely be a decision we make probably the day of [the match],” Jordan DeSilva, the Somerset captain, said. “He did train last night [Thursday] but he was limited.”Maybury bowled just one over in Somerset’s previous match against St George’s at Lords.Somerset are expected to make at least two changes to their squad from the one that beat St George’s by 46 runs as DeSilva confirmed that all-rounders Isaiah Richardson and Dalin Richardson “are both available”, having been ruled out last weekend through “work and personal commitments”.Back-to-back victories have catapulted fourth-placed Somerset into the title chase and they will now look to keep the momentum going heading into their second meeting of the season with St David’s.“It’s a good mood around the camp right now, not just because of the last two games, but even after the Rangers game that we lost,” DeSilva said. “We thought that a lot of positives came out of that game too.”DeSilva said he and his team-mates are up for the challenge against St David’s, who won the first encounter between the two clubs by 38 runs at Somerset on July 12.“It’s a good camaraderie in the camp, everyone is enjoying the last couple of weeks and we are just looking forward to a new challenge,” he said.Ricky Brangman’s team are also going into the clash high on confidence having handed leaders Southampton Rangers their first loss of the season last weekend.“St David’s beat Rangers who were undefeated last week,” DeSilva added. “We felt that we should have beat St David’s the first time we played them so we have more confidence this week. “We have a couple of players that were not available for that first game and we’re just going look to go out there and continue to perform.”Somerset’s recent success can largely be attributed to the prolific batting of late addition Kamau Leverock, who is on a rare hat-trick having blasted back-to -back centuries against Willow Cuts (119) and St George’s (126 not out) in his team’s last two outings.“Kamau is just doing what we knew he was capable of,” DeSilva said. “Kamau is doing the bulk of the work right now. But we know that somebody else is going to have to step up sooner or later when the day comes that he doesn’t come off.”St David’s will again be without wicketkeeper Ricardo Brangman who is serving the final game of a two-game suspension after being found guilty of breaching the Bermuda Cricket Board’s Code of Conduct during his team’s August 2 match against Bailey’s Bay at Somerset Cricket Club.Somerset’s match with St David’s starts at 3pm and will be preceded by the First Division Twenty20 between Flatts and Devonshire Recreation Club to commence at 11am.Meanwhile, leaders Southampton Rangers will be looking to get their title defence back on track when they face third place Bailey’s Bay today at Lords (3pm). Janeiro Tucker’s team presently top the Premier Division T20 standings on net run rate over second- placed St David’s.Rangers regular captain, Malachi Jones, could be available today having missed the previous two outings against St George’s and St David’s due to personal commitments.Meanwhile, the Bermuda Under 19s and Western Stars will kick things off today at Lords in a First Division Twenty20 clash to commence at 11am.Tomorrow’s remaining Premier Division match-up will see bottom dwellers Willow Cuts and St George’s do battle at Wellington Oval (3pm), with Cleveland and Warwick to face off in the preceding First Division Twenty20 fixture (11am).First Division side Somerset Bridge have a bye this weekend.
