SAN FRANCISCO -- Although Buster Posey reported Friday that the condition of his fractured right ring finger had improved, Giants manager Bruce Bochy said that his two-time All-Star catcher likely will rest for at least two more days "to get this thing to calm down."
Posey, who was injured on Tuesday in San Diego, took swings off a tee and was scheduled to play light catch. He wore a bandage and a small protective apparatus on his afflicted finger.
"It feels better today," Posey said. "Some of the swelling has gone down."
Posey felt certain that he must graduate from hitting off a tee to taking batting practice before he'll be cleared to play.
Bochy said that in Posey's absence, Hector Sanchez will remain San Francisco's primary catcher, though rookie Johnny Monell also is available. Bochy indicated that the 23-year-old Sanchez still has much to learn, saying, "The kid needs to play. ... This playing time can serve him well."
Bochy said that while Posey is sidelined, third baseman Pablo Sandoval, who caught 176 games in the Minor Leagues and 14 in the Majors, will serve as the team's emergency catcher.
Bochy backing off struggling reliever Mijares
SAN FRANCISCO -- Giants manager Bruce Bochy said Friday that he'll probably back off of using Jose Mijares as the first left-hander out of the bullpen, due to the reliever's recent struggles.
Mijares entered Friday having allowed 42.2 percent (19 of 45) of his inherited runners to score, an alarmingly high rate. That 19-run total is the highest in the Majors. Opponents are batting .322 off Mijares, the third-highest average among NL relievers. That includes a .593 (16-for-27) average with runners in scoring position in his last 12 appearances.
Consequently, Bochy said, "I might try to give Mijares a break."
Jeremy Affeldt's groin injury, which has sidelined him since July 21, has forced the Giants to rely excessively on Mijares. Affeldt continued his recovery Friday by throwing his second session of live batting practice, but Bochy didn't sound ready to activate the 12-year veteran from the disabled list.
"He looked a little rusty," Bochy said, adding that Affeldt will need to throw to hitters at least once more before being reinstated. "He looked a little hesitant, I thought, to let it go."
As a result, Bochy said that rookie left-hander Mike Kickham might receive more opportunities to pitch. Kickham, who started full-time this year with Triple-A Fresno, has made scoreless one-inning appearances in each of his last two outings.
• The Giants announced Friday that infielder Kensuke Tanaka cleared waivers and became a free agent, while left-hander Dan Runzler was outrighted to Triple-A Fresno. Both were designated for assignment on Tuesday to clear room on the 40-man roster.
• Entering Friday, the Giants had lost 36 home games, their highest total since finishing 37-44 at AT&T Park in 2008. That's the poorest home performance the Giants have sustained since AT&T opened in 2000. They also finished 37-44 in 2005. The Giants' worst home record since the franchise moved to San Francisco in 1958 was 35-46 in 1984.
• In his first 22 games at AT&T Park since breaking into the Majors in 2011, Arizona first baseman Paul Goldschmidt hit .333 (26-for-78) with five home runs and 20 RBIs. According to the Elias Sports Bureau, no other visiting player has driven in that many runs in San Francisco in that stretch.
