"We know where we're at," Mattingly said. "This series is a lot more important for us than for them. We need to win the series -- bottom line. We can't be swept. We need to pick up games and go forward."
A sweep by the Giants is something the Dodgers' faithful won't allow themselves to think about right now. It would be hard to blame the Giants fans if a sweep is all they can think about, especially after Friday's 5-2 victory, a win that extended San Francisco's lead over the second-place Dodgers to 5 1/2 games in the National League West.
"It's always good to get the first one, and there's a lot of attention on these games," Giants manager Bruce Bochy said after Friday's victory. "It's pretty intense out there, and really both teams played well, and it's always good to get the first one, no getting around that. Now we have to be ready to go tomorrow."
What's more, the Giants have won four in a row against the Dodgers and now lead the season series 8-5.
It will be up to Matt Cain to keep the Giants' winning streak alive Saturday. Cain allowed five runs in five innings against the Cubs in his last start, marking only the fourth time he has not pitched at least six innings this season. Three of those four starts have come in the last five weeks.
The Dodgers will counter with Chris Capuano. The lefty started the season with a 7-1 record and a 2.14 ERA but has struggled lately, going 2-6 with a 4.91 ERA in his last 10 starts.
