SAN DIEGO — The Giants flew into San Diego with the second-best record in baseball. They return to San Francisco with the third-best record in the division, suffering a two-game sweep at the hands of the Padres after losing, 5-3, on Wednesday at Petco Park.

Elias Díaz homered and scored twice for the Padres, and Fernando Tatis Jr. had three hits in a 5-3 win Wednesday over the Giants.

The Padres got off to a good start Tuesday night against one of the teams that recently supplanted them atop the National League West standings. A three-run first inning launched them to a 7-4 victory over the Giants that ended a losing streak at four games.
