I don't see the Padres sweeping the Nationals at home. Washington has had its ups and downs, but has not lost four in a row all season.

Padres starter Joey Lucchesi is helped by pitching at spacious Petco Park. He had a losing road record last season with a 4.24 ERA. San Diego is 1-4 in his last five road starts.

Nationals starter Jeremy Hellickson had an 0.75 ERA in two starts against the Padres last season.
