Roger Federer advanced into the semi-finals of the Sony Ericsson Open Thursday afternoon after his opponent, Gilles Simon, retired with a stiff neck trailing 0-3. Federer moves into the semi-finals in Miami for the second time in five years after reaching the final four stage in 2009.
A two-time winner here, the Swiss master has appeared in three finals at Crandon Park, and is looking to get back into the championship match for the first time since 2006, when he repeated as Miami champion by defeating Ivan Ljubicic in three tie-break sets.
