'Harmy Desperate For Final Chance'
Harmison - disappointed to miss the final last year.
Steve Harmison is doubly determined to fire Durham into a second successive Friends Provident Trophy final, according to coach Geoff Cook.
The holders take on Kent at the Riverside today for a place in the Lord's showpiece on August 16.
Harmison was out injured as Durham beat Hampshire to claim their first piece of silverware last year.
Cook sees the paceman's determination not to miss out again, coupled with his fierce desire to regain his England place, as the reasons why he has shone in the competition this year.
Harmison has taken 16 wickets in his nine Trophy appearances this season, behind only Kent's Yasir Arafat, and level with Tim Bresnan of Yorkshire.
Cook said: "Stephen was really disappointed to miss the final last year.
"He hid his disappointment brilliantly and supported the lads fantastically during the two or three days we were in London, but I think missing that game hurt him.
"He has bowled like a champion in this competition this year, so in terms of his performances over the last two seasons, he definitely deserves to get his just rewards in terms of playing for Durham in a final."
Ashes winner Harmison is currently out of the England side after being dropped during the tour of New Zealand earlier this year.
The 29-year-old has often struggled on tour and his absence from the Test arena this summer has suggested patience has run thin.
But, according to Cook, he remains as keen as ever to represent his country.
Cook added: "I never cease to be amazed by how Steve continues to bounce back. His resilience is incredible, and his desire to come in and buckle down under a fair amount of scrutiny is amazing.
"He repeatedly says that he wants to play for England, and that's brilliant. He never loses the desire to play for his country, but that desire doesn't sidetrack or affect his desire to do well for Durham as well.
"How he combines those two constantly, and keeps bouncing back from reversals and adversity, is absolutely brilliant."
England one-day captain Paul Collingwood was cleared to play for his county after it was initially thought he would sit out the match against the Twenty20 Cup holders.
Collingwood was due to rest ahead of next week's first Test against South Africa but expressed a desire to take part after featuring in the LV County Championship against Yorkshire earlier this week.
The all-rounder struggled for form in the recent Tests against New Zealand and his one-day series ended in controversy after his failure to recall run-out batsman Grant Elliott and a ban for a slow over-rate.
Kent were due to welcome back former Pakistan all-rounder Azhar Mahmood after resting him in the win over Surrey this week.
