The Davis Cup semi-finals line-up pits some unfamiliar rivals against one another – country-wise – but there will be familiar faces on either side of the net in Glasgow.
Australia’s trip to Great Britain is the two nations’ second meeting since 1986, with British tennis – read Murray family – coming a long way since their most recent World Group clash in 2003.
The only remaining competitor from the tie in Sydney 12 years ago is Australian stalwart Lleyton Hewitt, who is expected to front up on Saturday in the all-important doubles rubber.
The doubles will have added spice if, as expected, world number three Andy Murray wins both his singles rubbers, making it a must-win situation for Wally Masur’s men.
Conversely, the Brits will be viewing it as a crucial rubber – as number two Kyle Edmund is in doubt to appear after a training mishap, and could be forced to blood world number 141 James Ward.
Meanwhile, Australia pack three top-75 players – led by world number 23 Bernard Tomic, booming server Sam Groth and Thanasi Kokkinakis.
Murray has a 2-0 record against Tomic, thrashing the Australian number one in both their meetings, but in terms of the ‘other’ singles clashes, they appear to favour the visitors.
Great Britain captain Leon Smith said no risks will be taken with Edmund if he is not fully fit come Friday, after putting Ward on standby.
“Once we have worked this hard to get to a semi-final stage, we are certainly not going to leave anything to chance,” Smith said via daviscup.com.
“If it was a serious injury and suddenly there was one more injury after that, which can happen in sport, then I would look pretty crazy if I did not have any back-up here.”
Andy’s brother Jamie has made the final of the past two majors in men’s doubles
In Brussels, Belgium host Argentina looking to make the final of the competition decider for the first time in 111 years.
Granted, their 5-0 loss to the British Isles in 1904 was in a three-nation competition – so Johan van Herck’s Belgium side are shooting for their first final since the World Group was formed.
Leading out the Belgians is world number 15 David Goffin, who is the highest-ranked singles player involved in the hard-court tie.
The Argentines are back in the semis having reached the stage from 2010-13 before a shock first-round loss to Italy last year.
They are without major winner Juan Martin del Potro and Juan Monaco (both wrist) due to injury – with Leonardo Mayer their only top-50 representative.
Federico Delbonis and Diego Schwartzman are other singles options for captain Daniel Orsanic, while Carlos Berlocq is likely to be in the doubles rubber.
Goffin thrashed Mayer in their only career meeting in 2014, while Belgian number two Steve Darcis also has a win over Argentina’s number one.
Belgium and Argentina have met once in the competition, when the Europeans claimed a 3-2 win in 1948.
