Pace bowler Russell also handed new contract by Pears
Gareth Andrew has committed his future to Worcestershire by signing a new one-year deal.
The all-rounder is remaining at New Road despite an approach from Sussex - the side that were promoted alongside Worcestershire from Division Two of the LV= County Championship.
Having arrived from Somerset primarily as a seamer bowler, Andrew has developed his batting during his time with the Pears.
He scored a century off just 60 balls in a Clydesdale Bank 40 game against Surrey and also managed four half-centuries in first-class cricket.
Potential
"Gareth showed what he can achieve with his excellent 60 ball 100 against Surrey in the Clydesdale Bank 40 League," Worcestershire's director of cricket Steve Rhodes said.
"With some further progression with the ball he has the potential to be a quality all-rounder.
Meanwhile, the county have also handed a new two-year contract to promising pace bowler Chris Russell.
The 21-year-old made his senior debut in the two-day tour game against Pakistan and also played in two CB40 fixtures during the 2010 campaign.
Rhodes added: "Chris has worked really hard this summer and has done everything we have asked him to do.
"We are developing a young squad and feel Chris has a bright future as part of this process."
