PITTSBURGH -- After watching Sergio Romo lock down the save in Friday's 6-5 win, closer Santiago Casilla will likely watch Saturday's game from the bench, too.
Manager Bruce Bochy said the blister on Casilla's middle finger is just "a little better."
"With that said, though, we'll do all we can to stay away from him another day," Bochy said Saturday.
Casilla last made an appearance Thursday, blowing a save against Washington. In his last four outings, Casilla has blown three saves.
Romo, on the other hand, is 5-for-5 in save opportunities. He has pitched 25 innings this season and in that time has allowed just two runs and 11 hits. He's averaging 10.8 strikeouts per nine innings.
"Every time I'm in the game, I feel like that's my opportunity to save the game," Romo said after Friday's win. "I don't really look at it as a closer or whatever. I don't want that title. I don't need that title.
"We're a solid bullpen. Casilla's done a great job for us this year. ... Who doesn't have a rough patch during the season? We have all the confidence in the world in him. He's our closer. He is our closer. I'm just another guy in the 'pen that's trying to contribute."
Bumgarner to kick off Giants' second half
PITTSBURGH -- Madison Bumgarner. Tim Lincecum. Matt Cain. That's what the top of the Giants' rotation will look like for the second half of the season, manager Bruce Bochy announced Saturday.
Bochy said the Giants are still deciding whether to have Barry Zito or Ryan Vogelsong follow Cain, who is third in the rotation so he'll have "a chance to catch his breath" following the All-Star Game and all its baggage. Bumgarner gets to go first because he will have had the most time off.
Bumgarner and Zito are both lefties, but because their styles are so different, Bochy said, "It wouldn't be a big deal to [have them] go back to back."
When asked which of his starters needs the All-Streak break most, Bochy replied, "I don't think any of them do. I really don't. Vogey's fine. They're all fine. Really, Timmy's throwing well in his 'pens. 'Pens aren't what he needs right now. He needs to keep going out there."
San Francisco's second-half rotation will kick in July 13 for a three-game home set against the Astros.
Sandoval doesn't plan to catch in All-Star Game
PITTSBURGH -- With the news that Yadier Molina will not be attending this year's All-Star Game, leaving the National League with just two catchers, Pablo Sandoval might seem like a logical candidate to squat behind the dish if circumstances call for it.
After all, one of the two catchers on the squad is teammate Buster Posey, and Sandoval does have experience catching at the Major League level, having done so as recently as 2009.
But Sandoval lightly brushed aside the possibility Saturday before the Giants played the Pirates.
Sandoval said he's still got the skills, but admitted, "It's tough. It's a tough position."
In addition to Sandoval and Posey, the Giants will be represented by Melky Cabrera and Matt Cain in Kansas City.
Snubbed Vogelsong has impressive stats
PITTSBURGH -- Starter Ryan Vogelsong entered Saturday leading the National League with a 2.26 ERA. The last Giants pitcher to lead the league in ERA at the All-Star break was Atlee Hammaker, who did so in 1983 with a 1.70 mark.
Of course, Vogelsong is not an All-Star. The last pitcher to lead his league in ERA by the break and not make the All-Star team was the Marlins' Josh Johnson, who in 2006 paced the NL with a 2.21 ERA.
Vogelsong had thrown at least six innings in all 15 of his starts this season entering Saturday. It is the Giants' longest such streak since 1983, when Hammaker had 21 straight starts with six innings or more.
