Hi Jeff,
Don't completely discount Melville. We have not been beaten in our last 12 matches (and have won 10 of them), we have a young Welsh striker who arrived mid-season and has now scored 11 in 11 games (in what is a very good Div 1 this year), and back on the Melville No 1 pitch (now reopened) we have only lost once (to Roy Krishna in last year's semi) since 2012.
Aaron Scott is playing out of his skin in defence
Onehunga have lost Stuart Holthusen, their only goalscorer of note, who has gone to the US, and got humped 3-0 last week.
At the same stage last year we were hopeless underdogs to a much vaunted Birkenehad who led the premier league at the time, but managed to tuck them away at home, 3-2.
I concede that the betting money is obviously going on Onehunga - they have shortened from $1.75 opening - but in my view Melville are well worth a lazy $5 at those odds.
Hope this helps.
