BOSTON -- Shane Victorino's motivation to sign as a free agent with the Boston Red Sox this offseason makes a lot of sense for both sides.

For the first time in a five-year span, Victorino missed the playoffs in 2012 after playing for a perennial winner with the Philadelphia Phillies. The Red Sox have failed to earn a postseason berth in the previous three seasons. Boston's general manager Ben Cherington believes Victorino can help turn things around here. Victorino agrees and that's why he signed a three-year deal worth $39 million to play for the Red Sox.

"It wasn't fun to be home at the beginning of October," said Victorino, who will wear No. 18. "I plan on being (in the playoffs) this October and beyond."

Red Sox manager John Farrell has explained the type of roster he and Cherington are trying to create this winter. Both want quality players that will excel on and off the field and believe Victorino will add to what the Red Sox are trying to do.

There's already a buzz among his new teammates about the addition of Victorino to the Red Sox. It didn't take long for players, including Jon Lester, Clay Buchholz, Jacoby Ellsbury and David Ortiz to make their positive feelings known on Twitter once news broke that Victorino had agreed to a deal during the winter meetings last week in Nashville.

When he arrived at Fenway Park on Thursday for his introductory news conference, Victorino walked in and appeared upbeat, wearing jeans, sneakers and a hoodie.

"I'm going to be fun. I'm going to be loud. I'm going to talk a lot. You're going to get what you get," he said. "It's going to be me. I'm going to go out there and play 100 percent."

Ever since the club's historic collapse in September 2011 when the team quickly dropped out of postseason contention with a 7-20 record, many stories about a lack of clubhouse discipline surfaced, and the team spoke openly about changing the culture.

So, Bobby Valentine was hired as the manager, but Boston finished in last place in the AL East, costing the manager his job.

Former Red Sox bench coach Farrell was hired from the Blue Jays this offseason to turn things around. Cherington then signed Ortiz to a two-year deal and added Jonny Gomes, Victorino and possibly Mike Napoli, all of whom are considered good clubhouse guys to complement the existing core of players in Boston.

"When you're winning, everybody's happy. You guys are happy. I'm happy. We're all happy we're winning," Victorino said. "But at the end of the day, when you're not doing well, people are going to find reasons to why you've got to change. I don't think there's a need to change the clubhouse. These guys have won. They've been there and they've been to big games. I'm just trying to fit in. I'm going to be myself and bring that energy, that excitement and have fun."

Victorino credited the Red Sox's rich history, tradition and the makeup of the team for signing.

"I always pay attention to my counterparts and the last couple of years have been definitely tough for Boston and the organization," he said. "At the end of the day, we look beyond that now and we look forward to 2013 and being the organization that we can be. The game of baseball is the game of baseball, it happens sometimes like that and you can't put a finger on it.
