San Diego score their most runs at home since moving to PETCO Park in 2004, routing New York, 18 – 6. The last two runs are scored against Oliver Perez, who has pitched so poorly that manager Jerry Manuel has relegated him to the deepest reaches of the bullpen. Jerry Hairston hits a grand slam for the Padres, who remain two games ahead in the NL West.
