This time, Dustin Pedroia is going on the disabled list.
The second baseman resisted the idea in May when he tore the adductor muscle at the base of his right thumb. He missed six games and hasn’t been the same since, hitting .210 with a .282 on-base percentage and one home run in 105 at-bats.
Pedroia re-injured his thumb in Oakland on Tuesday and will be placed on the disabled list before Friday’s game against the Yankees according to team sources.
Globe colleague Nick Cafardo reported earlier Thursday that Pedroia would not be available this weekend. Scott Lauber of the Herald then reported that Pedroia was headed to the DL.
Pedroia was injured trying to make a diving catch. He said on Wednesday that it was the other side of his thumb that was hurting this time.
“It’s pretty frustrating,” Pedroia said. “I have a high pain tolerance, but I don’t know.”
If Pedroia’s stint on the DL is back-dated to Wednesday, he would be eligible to return on July 19 and would miss 11 games. That assumes the injury is not more serious.
The Red Sox are running out of infielders. Rookie third baseman Will Middlebrooks has missed the last three games with a strained left hamstring. The Red Sox used Mauro Gomez at third base in Oakland on Wednesday. He had not played the position since 2009 when was in Single A ball.
The only infielder on the 40-man roster not in the major leagues is Triple A Pawtucket shortstop Jose Iglesias. The Red Sox could add Pawtucket infielder Pedro Ciriaco to the 40-man roster and call him up to replace Pedroia.
Ciriaco was not in the lineup for Pawtucket on Thursday night at Rochester. He is hitting .301 this season.
• Daniel Bard had another rough night for Pawtucket. He faced four batters and did not record an out, giving up two hits and hitting two. In 12 games since his demotion, Bard has an 8.78 earned run average over 13 1/3 innings. He has walked 10, hit six and thrown six wild pitches.
