Seam bowler Jack Brooks and all-rounder David Willey have both signed new two-year contracts with Northamptonshire.
Brooks, 27, has taken 89 first-class wickets at 28.39 apiece since making his debut for the county in 2009.
His impressive form this season has been rewarded with a call-up to the England Lions squad for their match against Sri Lanka at Scarborough.
And despite interest from other counties, Brooks has committed himself to LV County Championship Division Two side Northants until the end of the 2013 season.
"I'm very happy to know that my future lies here at Northants for the next two years," he told the county's official website.
"The club has been great to me and I'm keen to repay their investment by helping Northants gain promotion to the top flight of the Championship and challenge for trophies across all competitions in the coming months and seasons.
"I also believe this is the best place for me to continue to develop my all-round game as I strive to further my career.
"It's very flattering to be courted by other clubs and I thank them for their interest but I've made this decision for purely cricketing reasons. I believe the club is going places.
"There are some talented youngsters here and I know that I'm one of the players the club is looking at to take the club forward. I'm looking forward to the challenge."
Northants head coach David Capel was delighted Brooks had agreed to extend his stay.
"This is an important signing for Northants and one that is mutually exciting for Northants supporters, and also for Jack himself," said Capel.
"He's done very well for us this year and it's good that he is marrying his own ambitions with those of the club. It's very pleasing that he has chosen to sign on for another two year period."
All-rounder Willey has also signed a two-year extension to his contract and will remain at the County Ground until 2013.
The Northampton-born all-rounder broke into the 1st XI in 2009, playing a crucial role in t20 and one day cricket. Willey has featured in 39 t20 matches, taking 27 wickets at an average of 16.
After signing the extension, Willey said: "I'm very happy, I've had three years at the club already and to be able to extend for another two years is brilliant. I'm Northants through and through, so this is fantastic news.
