OhMyIdiom (?) Rub Of The Green

Gosh It has been a while since I updated my idiom post. Been busy with stuffs, lots of them hohoh~ Anyway I was reading a post-match comment from a football game of Liverpool against United the other day, and I found this idiom, 'The Rub Of The Green'.

Meaning?
- if you have the rub of the green, you have good luck, especially in a sports competition

Example?
- Luis Suarez seemed to be having the rub of the green last night as he scored a hat-trick against Norwich City. WOHOOOO!!! We won 5-2 baby!!
