So here it is, the draw for the semifinal weekend. As you can see the journalists' impressions turned out to be correct - Jaite and Zabaleta have picked Leo Mayer as Argentina's second singles player while Charly and Horacio will contest the doubles rubber on Saturday - though not against Rosol and Vesely.
Here's a look at the match-ups and the schedule for the weekend:
Friday (3pm local)
Radek Stepanek vs Juan Monaco
Pico won two of their six encounters. The one time they met on clay and two years ago at the US Open when Stepanek had to retire. All other matches, all on faster surfaces, were won by the Czech.
Tomas Berdych vs Leonardo Mayer
On the Argentine team Leo has the best record against Berdych - for the sole reason that he has never played him before. The others all have but without any success (Pico 0-6, Charly 0-3, Horacio 0-2).
Saturday (2.30pm local)
Lukas Rosol & Jiri Vesely vs Carlos Berlocq & Horacio Zeballos
That's the theoretical version (and a little game the Czechs like to play). On court Charly and Horacio will be up against Berdych and Stepanek, a doubles team that can be summed up by a single stat - 91.7%. Their winning percentage in Davis Cup. Also with David this would've been an exceptionally difficult match.
Sunday (2pm local)
Tomas Berdych vs Juan Monaco
As mentioned above it's not exactly a promising record that Pico has against Berdych. But those two occasions where he managed to get close and take Berdych to five sets both took place in Davis Cup.
Radek Stepanek vs Leonardo Mayer
If this tie is really going to end with a live fifth rubber remains to be seen. In any case, as far as the match record goes Leo and Stepanek are tied at 1-1.
For Czech Davis Cup heroes Berdych and Stepanek this will be their homecoming - it's the team's first home tie since their triumph over Spain in last year's final. They're the reigning champions and the clear favourites to win this tie. On a surface that suits them - but not their opponents.
Will Pico, Leo, Charly and Horacio be able to rain on their parade? Will there be a miracle?
We'll find out this weekend.
