Northamptonshire have confirmed that Ben Duckett and Rob Keogh have both agreed new contracts with the club.
The pair, who have come through the ranks at Northants, have committed their futures to the County Ground until at least the end of the 2017 campaign.
"We are delighted that both Ben and Rob will be with us going forwards," head coach David Ripley told the club's official website.
"Both came through our academy system and we've seen them grow as young players and young men during their time here. I'm looking forward to seeing that continue over the coming years as our academy consistently provides home grown, first-class talent."
News of the extensions has come on the same day that England international David Willey left Northants to join Yorkshire.
