The Red Sox, after all, are emerging from the rubble of their worst season since 1965, when they lost 100 games. Bobby Valentine was dismissed after one season, the shortest tenure for a (non-interim) Boston manager in 78 years. The roster is punctuated by question marks. The fans, long past the euphoria of two World Series championships, are somewhere between apoplexy and apathy.

So why would Farrell, who spent four years here as Terry Francona’s pitching coach during better times, return now? “This is the epicenter of the game,” Farrell declared last week when he became Boston’s 46th manager, and third in as many seasons.

An epicenter is the point directly above the focus of an earthquake, and after two seismic seasons in the swampy Fens, the front office was looking for stability and familiarity amid the upheaval. So, the Red Sox went with the man they would like to have had a year ago, trading starting shortstop Mike Aviles to the Blue Jays for Farrell, who’d spent the previous two years as head man in Toronto.

“Put yourself in our position,” said Lucchino. “A guy comes in and says, this is a dream job for me, this is the epicenter of the baseball world. It makes you feel that the guy has a sense of the dimensions of the job and what he’s buying into.”

Farrell was in the dugout when the Sox swept the Rockies for the 2007 title. He was there when they lost the seventh game to the Rays the following year, when they were swept by the Angels in 2009, and when they missed the playoffs in 2010. Nobody had to walk him through the job description. “Not having sat in this seat but being close to it, to see the demands of the position, the passion of this region, the energy that is in this ballpark every single night . . . ” said Farrell.

Those who know the man well weren’t surprised he cycled back to Yawkey Way. “Johnny loved it there,” said Arizona Diamondbacks pitching coach Charles Nagy, who was Farrell’s teammate in Cleveland. “He enjoyed the city, enjoyed the team, enjoyed the organization. The fit was there for him.”

After the Valentine misfit, Sox officials were in no position for another risky relationship, so they went with John Wayne in sanitary socks, a straight shooter whose personality and professional profile they knew by heart. “It was very comfortable,” Lucchino said about their meeting. “You sit down, you don’t spend the first hour of an interview finding out background and family and personality. You hit the ground running, and we did. I didn’t know what kind of Chinese food John liked, but we do have a high degree of familiarity.”

General manager Ben Cherington has known Farrell since he was Cleveland’s farm director, a résumé point that the Sox, now in a reconstruction zone, found attractive. “It was one of those things that just bounced off the page,” said Lucchino. “Because player development is the rock on which you build the church.”

Had Farrell stayed on the front office path, he likely would have become a GM himself. But the lure of the uniform was irresistible. “When you track as an executive there comes a point where you can’t go back to the field,” observed Padres manager Bud Black, Farrell’s former Indians teammate who later spent four years with the club as a special assistant to the general manager.

Farrell had been on the field for a decade, pitching 116 games for the Indians, Angels, and Tigers before retiring in 1996. Had he not been betrayed by his right elbow, which twice required surgery, he likely would have played in two World Series. He was a tall, sturdy Jersey guy whose father, Tom, had played on the same Cleveland minor league club as Rocky Colavito and Herb Score in the ’50s and who’d been an overpowering figure on the mound at Shore Regional High School in Monmouth County.

“The reason why we were so successful was because of John,” recalled Fred Kampf, a former Oakland farmhand who coached at Shore for nearly three decades. “I had three nice high school pitchers and they could go five innings. He would come in and blow people away for two innings and we’d win.”
