Prior to Tuesday's game, manager Bruce Bochy had nothing new to report regarding his leadoff hitter. He expects that to change "in the next day or so."
Pagan has taken batting practice the past two days but said Monday night that he wasn't able to "swing 100 percent" because of the back problems.
"I'm all right," Pagan said after the game. "I wouldn't say great, but I'm OK."
Added Bochy on Tuesday: "There's a fine line between batting practice and playing in the game."
One injured Giant scheduled to soon be playing in games is first baseman Brandon Belt, who Bochy said would likely start a rehab assignment at Class A Advanced San Jose on Thursday.
"He feels good and he's ready to go," Bochy said of Belt, who has been fielding, running and has progressed from hitting off a tee to hitting off a pitching machine.
Belt broke his left thumb May 9. He's hitting .264 with nine home runs and 18 RBIs in 35 games this season.
In other injury-related news, Bochy said Ehire Adrianza's right hamstring strain is similar to the injury Matt Cain had earlier this season and Marco Scutaro, who has remained sidelined by back problems all season, will begin an injury rehabilitation assignment Tuesday with the Arizona League affiliate.
Scutaro, 38, is expected to play three innings. That would match the game activity he has accumulated all year. Scutaro's lone appearance in a Giants uniform was a three-inning stint in a Cactus League game on March 17.
The Giants had hoped that Scutaro, who played through a painful finger injury last year, would return healthy this year to anchor second base. Instead, San Francisco has used four different starters at that position.
