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 reinjured the thumb in Oakland Tuesday and will be placed on the disabled list before Friday’s game against the Yankees, according to team sources.

Pedroia was injured trying to make a diving catch. He said 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 were backdated 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 Sox used Mauro Gomez at third base Wednesday. He had not played the position since 2009 while in Single A.

The only infielder on the 40-man roster not in the major leagues is Pawtucket shortstop Jose Iglesias. The Sox could add PawSox infielder Pedro Ciriaco to the 40-man roster and call him up to replace Pedroia.

Ciriaco was not in the lineup for Pawtucket Thursday night at Rochester. He is hitting .301 this season.

Ortiz angry again

In the latest of what has been a series of rants about his one-year, $14.575 million contract, David Ortiz told USA Today he would be open to leaving the Red Sox.

“If you go crazy and give contracts to whoever comes along despite not knowing how they’re going to do, then you don’t give me my due consideration, even though I do my thing every year, [expletive] that. I’m going to be open to anything,” he said. “My mentality is not going to be, ‘I like it here.’ It’s going to be, ‘Bring it to the table, and we’ll see what happens.’ ”

Ortiz also called being offered arbitration last winter “humiliating” and “embarrassing.”

The comments came Wednesday before the Sox were swept in a three-game series by the Athletics and Ortiz hit his 400th career home run.

Ortiz is the highest-paid, full-time designated hitter in the game but has complained several times about playing on a one-year contract given his accomplishments.

Rough time

Daniel Bard had another rough night Thursday for Pawtucket. He faced four batters and did not record an out, giving up two hits and hitting two. He also threw two wild pitches. In 12 games since his demotion, Bard has an 8.78 earned run average over 13⅓ innings. He has walked 10, hit six, and thrown six wild pitches . . . In his last six appearances (three starts, three in relief), lefthander Franklin Morales has a 1.35 ERA over 26⅔ innings and has struck out 33 with three walks . . . The Red Sox and Yankees have played 188 regular-season games since the start of the 2002 season. The Yankees have won 95, the Sox 93.
