Jamie Murray unaware of Grand Slam landmark as he reaches another final

Jamie Murray is one victory away from becoming Britain's most successful grand slam player of the Open era after he and partner Bethanie Mattek-Sands reached the mixed doubles final at the Australian Open.

If the British-American duo win on Saturday, Murray will claim his eighth slam title, moving him clear of Virginia Wade, with whom he currently holds the national record.

"I didn't know that," said the 33-year-old. "It's not something I'd ever thought about but I guess that's a cool record to have. But I've not done it yet."
