John Farrell pledged to create "an up-tempo, aggressive style of play" after being formally introduced as the 46th manager of the Boston Red Sox at Fenway Park on Tuesday.
A Red Sox pitching coach from 2007-10, Farrell returns to Fenway Park after spending the last two seasons in charge of the Toronto Blue Jays, where he compiled a 154-170 record.
"As far as what you can expect from us on the field, I truly believe in an up-tempo, aggressive style of play," Farrell told a news conference. "It will certainly take into account the strengths of our roster, that's a given.
"To play that style of game, it does create an attitude which I think is critical to win at the major league level.
"And that's to be relentless - with our effort, with our preparation, with our work and the competitiveness that we take to the field every night. That's a non-negotiable as far as I look at it."
The 50-year-old takes over from Bobby Valentine, who was fired by the Red Sox earlier this month after just one season in which Boston went 69-93 to finish bottom of the division.
World Series champions twice in the last eight years, the Red Sox finished 26 wins behind the division champion and rival New York Yankees.
Farrell, who along with right-handed pitcher David Carpenter joined the Red Sox from Toronto in exchange for shortstop Mike Aviles, was delighted to be back at Fenway Park.
"This is an incredible privilege to be standing here today," he said. "Boston is, in my mind, the epicenter of the game."
