CHICAGO -- Back stiffness forced Giants center fielder Angel Pagan from the lineup for the second straight game Tuesday as San Francisco opened its two-game Interleague series against the Chicago White Sox.
"He's making a little progress, but not as much as we hoped," said Giants manager Bruce Bochy, who rated Pagan's playing status as day to day.
Bochy said Pagan underwent an MRI that revealed inflammation, adding that he wanted to see the leadoff hitter's ailment "calm down" before he would rejoin the lineup.
Pagan also missed starts June 8-9 with a leg ailment. He entered Tuesday batting a team-best .307 with 11 stolen bases in 14 attempts.
