Now, the roles are reversed as the Giants have won back-to-back games and the Padres have slumped to four consecutive defeats. Game 2 of this four-game set at Petco Park in San Diego starts at 9:40 p.

These two weeks in which the Padres are playing only the Giants and Dodgers have provided some mood swings. The Padres moved into first place in the National League West with a sweep in San Francisco last week and fell back into second place when they were swept in Los Angeles over the weekend.

Nick Pivetta allowed a leadoff homer by Jung Hoo Lee and then settled down to tie his season high with 10 strikeouts in six innings and lead the San Diego Padres to a 5-1 victory against the San Francisco Giants on Tuesday night.
