Pena was the second candidate to interview for the position left open when the team fired Bobby Valentine the day after the season. Los Angeles Dodgers third-base coach Tim Wallach talked to the club about the job on Friday in Boston.
The Yankees, who are down 0-2 to the Detroit Tigers in the American League Championship Series, were off Monday, which freed up Pena for the interview. The 55-year-old former catcher played 18 seasons in the majors, including four in Boston, and managed the Kansas City Royals from 2002-2005. In 2003, he was named AL Manager of the Year. He resigned midway through the 2005 season after his team started 8-25.
Pena joined the Yankees' staff in 2006 and interviewed for their managerial opening after Joe Torre's departure. The team named Joe Girardi as skipper, and Pena has been on his staff since, serving as first-base coach and in his current role as bench coach.
Hale, 51, who was on Terry Francona's staff in Boston from 2006-2011, was not granted an interview by the Red Sox in their managerial search last winter and was not retained on Valentine's staff. He joined the Orioles shortly thereafter.
Ausmus, 43, spent 18 years as a catcher in the majors before joining the Padres in 2010 as an assistant.
Wallach met with the Red Sox on Friday, had dinner with general manager Ben Cherington and his staff, and flew back to his home on the West Coast on Saturday.
"I thought it went well," said Wallach, a five-time All-Star as a third baseman who twice before has interviewed for big league managing jobs. His first was in 2006 with the Padres, and the second was in 2010 with the Milwaukee Brewers.
Wallach also said he doesn't know why the Red Sox did not ask to interview him last year before Valentine was hired.
"And I didn't ask them about it," he said.
The man widely considered the team's preferred candidate, Toronto manager John Farrell, is under contract with the Blue Jays for another year. As of Monday morning, Farrell had not been contacted regarding the Red Sox job, according to a baseball source.
Wallach said he was confident the Red Sox viewed him as a serious candidate for the job.
"I don't think they would have brought me here unless they were serious," he said. "But I understand the process that has to be gone through. I honestly believe they wouldn't waste their time."
