If Ireland win, they'll overtake Zimbabwe in the ODI rankings, and they're off to a reasonable start - Australia won the toss and opted to bat, and they're at 51/1 after 12 overs, with Ireland holding them back fairly well.
Have to admit I have my Ireland hat on for this one, and even though it wouldn't help Zim in the rankings I'm cheering with the Blarney Army for an Ireland win. GO IRELAND!
