Worcestershire director of cricket Steve Rhodes says that having a fully-fit Gareth Andrew operating in 2015 will be "like having a new signing".
The ex-Somerset all-rounder, 31, has shown up well in pre-season training after missing most of last summer following a fractured bone in his back.
And Rhodes is keen for him to recapture last summer's early season form.
"He bowled beautifully for the first four games, taking 20 wickets," Rhodes told BBC Hereford & Worcester.
"If he'd carried on in that sort of form, there's no telling where he'd have ended up.
"But he's fit, showing up well and having him out there bowling again it will be like having a new signing for us."

Andrew, who has been troubled by his back problem for the past year and a half, has had more than his fair share of injuries since arriving at New Road in 2008.
In his seven seasons with Worcestershire, he has managed only one full Championship campaign in 2011, when he helped the county stay in the top flight, the only time they have managed that feat in four attempts.
Worcestershire were promoted back to Division One for the fifth time in 12 seasons in 2014 and, having re-signed Pakistan spinner Saeed Ajmal, their chances of staying up again, as in 2011, look to have improved.
After returning to indoor training following the Christmas break, Worcestershire's players are concentrating on fitness work before heading off on a 10-day pre-season trip to Abu Dhabi next week.
Worcestershire's season back in Division One begins with a visit from county champions Yorkshire to New Road, starting on Sunday 12 April.
