Padraig Harrington insists he is in optimistic mood ahead of his USPGA Championship defense despite his indifferent form thus far this year.

Having remodelled his swing, the Dubliner has struggled for results in 2009 following two years of unprecedented success.
However, he remains confident his work will ultimately pay dividends and is upbeat about his chances, starting at this week's WGC-Bridgestone Invitational at Firestone Country Club.
""Very positive,"" Harrington responded when asked to assess his mood ahead of two very important weeks.
