he's made the DC team for next week
Great achievement for him, he must be happy.
If these doubles result in a 61 62 loss against Kubot, I wouldn't be so happy with it. Screw those doubles, focus on singles! Finally things were clicking and then such a loss...
It's not all about singles, and besides you may not give importance to it only Horacio can decide whether it's important or not for him. I suppose he likes playing it, so it's important for him. He won a trophy at his home tournament last week partnering Sebastian Prieto who is a great doubles player and this week he already won a match together with Pico Monaco. He is a talented doubles player and likes playing it, so what.
Also he was called for DC as said before, which may be a result of both his singles and doubles success, so it's paying off for him.
Stop complaining a little bit, not only here.
