David, 23, was voted Glamorgan's young player of the year for the second successive time last summer after taking 57 first-class wickets. His brother, Adam, who is four years younger, has played for England U-19s, and has recently flown out to Malaysia for in preparation for their tour of India. Adam is yet to play for the Glamorgan first team, but he opened the bowling for MCC against Sussex in the opening first-class match of 2004.
"We're delighted that both David and Adam have committed to the Club for the next three seasons," said Mike Fatkin, Glamorgan's chief executive. "Both are highly regarded within the game and it's great news for us that they have agreed to sign new contracts. Glamorgan remains strongly committed to the development of home-grown players and with an excellent Academy, a team of very capable coaches and a group of very talented emerging players just below the full time staff we are confident that this policy will continue to bear dividends."
