SAN FRANCISCO -- There's only so much the Giants can do to extricate themselves from the mess they created the first half of the season.
Yet, that isn't keeping them from trying new things. On Tuesday, that meant general manager Brian Sabean signing free-agent outfielder Jeff Francoeur and promoting Kensuke Tanaka from Triple-A Fresno.
The moves did little to slow the Giants' nose-dive. The New York Mets scored five times in the eighth inning to turn a tie game into a 10-6 rout before a sellout crowd at AT&T Park.
"We're getting tested like we've never been tested before," manager Bruce Bochy said after the Giants lost their third straight game, seventh of eight and 18th of 23.
There's no way
"They battled back," Bochy said. "We did a great job of moving guys, we manufactured runs. They did a lot of great things."
In the end, the Giants pitching didn't hold up well enough, Bochy said.
Bochy inserted Tanaka into the starting lineup in hopes the 32-year-old could provide a spark in his major league debut. Bochy also put Marco Scutaro into the No. 3 spot of the order for only the second time this season.
Tanaka responded by making a leaping catch of a fly ball at the top of the left field wall to end the second inning and twice being in the middle of game-tying rallies.
In the process, he earned another start Wednesday, Bochy said.
"He made a great catch in left field, he had some good at-bats," Bochy said. "It was a good debut for him. He looked comfortable."
Once again, Bochy said his players are united in their resolve to emerge from their prolonged funk. The key is stringing together a few good games.
"Sometimes these guys put a little too much (pressure) on themselves," Bochy said.
Scutaro added two singles and a sacrifice bunt. He, too, played a pivotal role in two Giants rallies.
All that got lost awash a five-run eighth by the Mets, a rally capped by a Marlon Byrd grand slam to put the game out of reach and send most of the fans toward the exits.
Francoeur, 29, batted .208 with three home runs and 13 RBIs for the Kansas City Royals before he was designated for assignment late last month.
Bochy likened the signing of Francoeur to the Giants adding veteran outfielder Pat Burrell during the 2010 season. Burrell played a key role in the Giants winning the World Series that season.
"Sometimes a change of scenery is good," Bochy said of Francoeur.
The Royals are on the hook for most of Francoeur's $6.75 million salary.
"We're struggling against right-handers, and he's been swinging the bat as well as anybody down there ...," Bochy said. "So, why not him?"
Bochy said Tanaka is here as a left fielder for now, given the Giants are set at second base.
