With the Phillies in San Francisco to start a three-game series on Monday, Bochy is looking to make it up on the fly when it comes to deciding who will close for the Giants going forward.
For now, left-hander Javier Lopez and right-handers Sergio Romo and Santiago Casilla will share the duty, Bochy said.
"You can look at the way we've set up Lopez and Romo and how we've gone with matchups between those two, and we've ended up using Casilla in the ninth," Bochy said on Sunday. "For the last six outs, we'll use the best guys available."
It will be a world different from the one in which the Giants knew that if they could get the game to Wilson with a lead, they were generally in good shape.
"Ideally, you'd like to have one guy, but I don't know that we do have that one guy," Bochy said.
Lopez has a 21-11 career record with five saves, and is 1-0 in four games with 1 2/3 hitless innings.
Romo has a 16-7 career record and has appeared in two games this season, working two innings and giving up a hit and no runs.
Casilla is 15-8 in his Major League career, with 12 saves. He has appeared in three games this season (2 2/3 innings), and given up one hit and no runs.
Phillies: Thome nears another milestone
Jim Thome has 96 home runs with the Phillies. If he reaches 100, he will become the fourth player in Major League history to have 100 home runs with three teams. He hit 334 for Cleveland and 134 for the White Sox.
Alex Rodriguez (Mariners, Rangers, Yankees), Hall of Famer Reggie Jackson (A's, Yankees, Angels) and Darrell Evans (Braves, Giants, Tigers) are the others.
Giants: Sandoval streaking
Pablo Sandoval has hit safely in each of the first nine games after singling in the sixth inning on Sunday.
Monday's game will feature a matchup of two of the best starters in the National League in recent years, with Roy Halladay going for the Phillies and Tim Lincecum for the Giants. The two were pitted against each other twice during the 2010 NL Championship Series but will meet for the first time in a regular-season game on Monday. Lincecum earned the win and Halladay took the loss in Game 1 of that series in 2010, with the situations reversed in Game 5.
