However Harmon is less positive about the title chances of World No 13 Lee Westwood, even though the 40-year-old told Monday's Special Report that he is confident he can mount a serious challenge.
Westwood almost matched his best-placed Masters finish - second spot in 2010 - last year when he finished in a four-way tie for third spot.
The Worksop-born golfer admitted afterwards that his quest for a first Major had been undermined by a putting display that was not up to scratch and Harmon believes Westwood's form on the greens is still not good enough.
"I think Westwood's short game keeps him from winning Augusta, I think it's the one Achilles Heel there is in Lee's game.
"Tee to green he is as good as anybody there is in the world and has been for the last 10 or 15 years but I think his inability to get up and down around the greens really hurts him in Major Championships."
