Kevin Sharp says Worcestershire opener Ollie Westbury is reaping the benefits of his high work ethic and is "only going to get better."
Westbury has celebrated signing a new contract by scoring back to back centuries in the Second Eleven Trophy against Derbyshire and MCC Young Cricketers.
He went through a winter programme designed to build up his physical strength and also to enhance his stroke play alongside his desire to bat for long periods.
Batting Coach-Second Eleven Coach Sharp, whose side have won their opening four Trophy games, said: "The lad has worked so hard. He has worked hard on both his cricket and his fitness.
"Credit to Ross Dewar (Strengthening and Conditioning Coach) and Ben Davies (Head of Sports Science) who have looked after him in the winter.
"His work ethic is very high. He came on the scene as more of a traditional longer form batsman.
"But he has worked so hard on his white ball skills and played a lovely knock the other day.
"He is a bit physically stronger now and he has got some good rewards for the work he has put in.
"The lads really do work hard on their game and practice and make the most of their abilities."
In terms of his new contract, Sharp said: "It is well deserved, he is an outstanding lad, he has worked so hard, he is a good player.
"He is only going to get better, he is a reliable sort of cricketer.
"You know what you are getting from Ollie and everyone is really, really pleased for him."
