Youngsters Azeem Rafiq and Gary Ballance have new signed contracts with Yorkshire.
Off-spinner Rafiq, 20, and batsman 21-year-old Ballance have committed to the county for another two years.
"We are delighted to offer contract extensions to these very talented youngsters who have shown such promise in an otherwise disappointing season," said club chief Martyn Moxon.
Yorkshire have also confirmed that new deals have been offered to Moin Ashraf and Joe Root, but the duo have yet to make a decision on their futures.
