The 24-year-old has only played four times this season, all in the Bob Willis Trophy in which he has averaged 29.75
Northamptonshire have confirmed the retention of Ben Curran on a new two-year deal.
The 24-year-old has scored 1,013 runs across all formats during two seasons at Wantage Road.
He has featured just four times this term, with all outings coming in the Bob Willis Trophy.
Curran, brother of England and Surrey's Sam and Tom, averaged 29.75 but going forward wants to make more of an impact in limited-overs cricket.
"It’s an exciting time for Northamptonshire cricket and I’m really enjoying being a part of it," said Curran, who has signed up until 2022.
"We’ve got a good core group of young players and hopefully we can go on and win some trophies in the years to come.
"I worked hard on my game over the winter and made a few changes which I feel paid off. Hopefully next summer I can start converting my strong starts into match winning scores.
"Ultimately I want to help the team win as many games as possible.
He added: "I feel the work I have put into my game means I have the skills to succeed and perform consistently across all three formats, I haven’t got many opportunities in white-ball cricket yet but I feel my game is in good order to take my chance when I get it."
