A further update, since it has been a while and Liv continues to climb the rankings
Liv is now at a career high WR57 and back to GB #1 ahead of Heather and will climb further in the next rankings. With a lowest counter of 85 points (x2) she will drop a maximum of 41 points by the end of the year
Since teaming up with Tereza Mihalikova they have reached
Wimbledon - 3rd round
WTA1000 - QF Cincinnati
WTA500 - SF at Monterrey (and still to play)
WTA250 - F at Hertogenbosch, SF at Palermo, QF at Birmingham
Just to add, Liv's current regular partner, Tereza Mihalikova also has a new CH this week of 41, just 92 points behind Liv and closing as their points align.
Following on from the above, Liv's new career high doubles ranking, now 29 on live rankings, may well be the highest ever for any British woman - for about 50 years or so anyway.
Among the current crop, only Heather comes close, and none of Baltacha, Keothavong, Durie, Barker, Wade - most of whom played very little doubles.
