Nadal and Federer advance in Miami

The Spaniard and the Swiss advance in Miami and look set to go for their first clash in 2011 (semifinals in Miami).
Nadal had a relatively easy victory over his close friend Feliciano Lopez. He did not concede any break point and he managed to break 3 times his opponent.
Federer had a more difficult task against the Argentine. The Swiss won the opener only at the tie break and then the second set finished 6-4 for the world nr.3
If we are lucky we may see another Federer-Nadal classic in a couple of rounds…
