Surrey have announced that batsman Tom Maynard has tragically died at the age of just 23.

The batsman, who was considered one of England's brightest prospects, is believed to have been killed in the early hours of this morning by a London Underground District Line train.

"BTP officers were called to the line near Wimbledon Park London Underground station on Monday, 18 June after a man was struck by a District line train," said a spokesman for the British Transport Police. "The incident was reported to BTP at 5.03am and was also attended by Metropolitan Police officers.

"London Ambulance Service medics attended but the man, believed to be 23 years old, was pronounced dead at the scene.

"The incident was reported to BTP at 5.03am and is currently being treated as non-suspicious. A file will be prepared for the coroner."

Meanwhile, Surrey chairman Richard Thompson has paid tribute to the former Glamorgan player.

"Our thoughts at this awful time are with Tom's family and friends and all those that were close to him," Thompson said in a statement.

"Tom Maynard was a prodigiously talented young batsman who had made an incredible start to his career and was clearly destined for far greater things. The impact Tom made in such a short period of time for Surrey CCC spoke for itself.

"There is a profound sense of loss at the passing of Tom. To lose anybody at such a young age is an utterly senseless tragedy."

Tom was the son of former batsman Matthew Maynard, who played for Glamorgan as well as competed in Test and one-day cricket for England.
