Great Britain 2-1 Australia

Dominic Inglot was originally supposed to partner Jamie Murray in the doubles, but in a late change, captain Leon Smith opted to bring in the world No. 3 instead, per British Tennis:

Per the Daily Mail's Stuart Fraser, the match was only the second time the brothers had lined up together in their home country, and the pair took some time to find their rhythm, as the Australians broke them in the first set following some confused positioning to go 4-2 up.

From there, Hewitt and Groth remained in control thanks to some strong serving on their part.

The Scots soon became much more fluid in their play, though, and after initially following serve broke their opponents thanks largely to some outstanding volleys from Jamie. Fraser highlighted the older brother's performance at the net:

They did indeed hold in the next game to give them a commanding lead in the set and duly levelled the scores at 1-1.

Hewitt and Groth raced to a 4-1 lead in the third set, but some excellent alternate serving and volleying from the Murrays and some loose play from Groth saw the brothers win five consecutive games to put their noses in front for the first time.

Former British No. 1 Andrew Castle was among those leading the praise for the pair on social media:

Some poor serving from Jamie handed Australia an early break in the fourth, but two-time Grand Slam winner Andy really began to flex his muscles, his powerful and accurate returns inspiring GB to break back.

Hewitt and Groth were also battling hard, and it took some excellent serving from Jamie in the sixth game to save two break points and eventually hold. He did so again at 5-4 down as the Australians failed to see out three set points.

They showed remarkable resilience, though, and with the Murrays serving for the match, they broke the Scots to force a tiebreaker and then saved a match point before closing out the set, per one-time U.S. Open finalist Greg Rusedski:

The fifth set began much as the others did, this time with GB going an early break ahead before the Australians scrapped and fought their way back to 3-3. The match then followed serve, with Andy proving deadly with several powerful smashes.

Australia soon found themselves serving to stay in the match at 4-5, but the nervy Groth could not hold on as the Scots clinically took advantage of some poor serving before Hewitt hit a long return to hand them the match.

The win provides GB with a crucial point ahead of the final two rubbers on Sunday.

However, with this match lasting close to four hours, Andy could well find fatigue to be a problem after also playing a singles match on Friday, so it's all still to play for as far as Australia are concerned.

Belgium 1-2 Argentina

There were changes for both Argentina and Belgium's lineups on Saturday, with Mayer coming in for Diego Schwartzman and Steve Darcis replacing Kimmer Coppejans.

This match was somewhat less dramatic than the other, but nevertheless the Mayer and Berlocq played well on the way to securing a vital point for Argentina against a spirited Belgian pairing.

The pair raced through the first set, breaking Belgium twice and hitting 17 winners while their opponents made 16 unforced errors, according to the tournament's official website.

Berlocq and Mayer began the second set in a similar fashion to the first, and tennis writer Leigh Walsh was impressed with their display:

As the Davis Cup noted on Twitter however, Darcis and Bemelmans refused to lie down:

However, the Belgians' play at the net left something to be desired, as indicated by their 16 successes from 36 attempts in the set, per DavisCup.com.

Their profligacy in closing out points at the net allowed Argentina back into the match as they comfortably took the tiebreaker:

The Belgians were wasteful again as they failed to take their first four break points in the third, though their strong serving ensured the Argentinians failed to take their three.

As a result, the set duly followed serve until Belgium finally made a breakthrough late on, and despite some intense pressure they valiantly held their own serve one last time to see out the set.

An evenly contested fourth set followed, Argentina hitting more winners but also more unforced errors than their opponents as both pairs served reasonably well and broke each other once apiece.

The set and match ultimately went to a tiebreaker, with Berlocq and Mayer's more clinical play in the key moments eventually telling:

With both Mayer and Darcis emulating Murray and playing a singles match on Friday and a four-hour doubles match on Saturday, Sunday should be a fascinating final day as they take on David Goffin and Federico Delbonis respectively.

Goffin should be able to equalise for his team against the fatigued Mayer, so expect the tie to come down to the decisive fifth rubber.
