"I think I will have more for you when he comes in tomorrow," manager Bruce Bochy said after Saturday's 10-2 loss to the Reds.
Enter Hall, who becomes the latest piece of patchwork the Giants are using to stem the tide of injuries to position players that has engulfed the team in recent weeks.
The 31-year-old Hall hit .224 with a .272 on-base percentage in 46 games this season before being released by the Astros on June 4. A veteran of parts of 10 seasons in the Majors who has played second base, third base, shortstop and all three outfield positions, Hall has a .249 career average and batted .247 in 120 games with the Red Sox last year.
Bochy said he and Sabean talked during and again after Friday's game and agreed that Hall was their best option at the moment.
"That's a good name to have available because of his versatility, and he's very athletic," said Bochy, who worked with Hall on an all-star tour of Japan several years ago.
For Hall, getting the call from the Giants just days after the Astros let him go was as good a call as he could get. He was just back at his house in Arizona, playing video games when he got the call.
"This is a good option for me," Hall said Saturday. "I've heard this is a good clubhouse. I'm ready to contribute whatever they need from me. I can help this team win."
Exactly how and when remains to be seen, somewhat. Hall hadn't played in more than a week, but he did enter Saturday's game on a double-switch in the fifth inning. Manny Burriss was the starter at second base Saturday, shifting to shortstop when Hall entered, and he figures to see his name on the lineup card going forward.
"Manny's going to get his time out there, too," Bochy said.
With Pablo Sandoval a few more days away from returning to the active roster following surgery to remove a fractured hamate bone in his right hand and Mike Fontenot (left groin) even further away from his return, Hall provides veteran help at a time when the Giants need it most.
"We need some depth right now, and he gives us that at every position in the infield and the outfield," Bochy said.
The Giants will pay less than $300,000 of the remaining portion of Hall's $3 million salary, while Houston remains responsible for the rest. It was previously reported that Hall had been drawing interest from the Orioles and Nationals.
Sanchez, the 33-year-old who has been perhaps the Giants' most consistent hitter this season, became the fifth member of San Francisco's Opening Day starting lineup to go on the disabled list and the 12th Giants player overall to hit the DL. The other starters were third baseman Sandoval, catcher Buster Posey (fracture and torn ankle ligaments in left leg), center fielder Andres Torres (strained left Achilles) and first baseman Brandon Belt (hairline fracture in left wrist). Outfielder Cody Ross (right calf), who likely would have been in the Opening Day lineup, and closer Brian Wilson (strained left side) began the season on the DL.
Bochy has tried to keep the mounting injuries from affecting his even-keel approach to the game, but he admitted Saturday that these incidents affect him just like they do fans who see their favorite players go down to injury.
"I hurt for these guys," Bochy said. "When I was standing over Buster Posey, that hurt. It really did to see him busted up. To go out and see Freddy with his shoulder out, it hurts. I'm not going to lie. It does bother me. For us to have major injuries like this, it bothers you, there's no getting around it."
But, as Bochy said, it goes with the territory and it's all about how you handle it.
"You move on because you have to," Bochy said.
