The Boston Red Sox won the World Series after a 6-1 win over the St Louis Cardinals in game six at Fenway Park.
Shane Victorino's three-run double in the third inning was followed by the hosts scoring three more in the fourth to comprehensively wrap up a 4-2 series win.
After a scoreless first inning, Red Sox pitcher John Lackey got out of a jam in the second, striking out Jon Jay with two runners on and having been moved up by catcher David Ross' error. Ross was then the third man out as Michael Wacha responded in kind.
Victorino's monster first hit of the series scored Jacoby Ellsbury, David Ortiz and Jonny Gomes to give the Sox a 3-0 lead after three.
Stephen Drew opened the fourth with a solo homer and visiting pitcher Michael Wacha was taken out of the game with two out and two on.
Replacement Lance Lynn allowed Mike Napoli to score Ellsbury and Victorino, again at bat with the bases loaded, to see in Ortiz, with both runs charged to Wacha.
The Cardinals' woes continued as Matt Carpenter fumbled Ellsbury's ground ball. The same runner then failed to steal second base but got back to first despite four fielders attempting to stop him.
Lackey was finally withdrawn with two out in the seventh, Carlos Beltran having scored Daniel Descalso for the Cards' only run, and was given a rapturous reception by the crowd. Junichi Tazawa took his place with the bases loaded and picked up the final out.
It remained 6-1 going into the ninth inning and Boston sent in closer Koji Uehara to finish the job, striking out Carpenter after Jay and Descalso both flied out to Gomes.
The win marks a stunning comeback for the Red Sox after they finished last in the American League East last season. The 1991 Minnesota Twins were the only previous team to go from "worst to first" in MLB.
It was also Boston's third World Series in 10 years and owner John W Henry, after lifting the trophy, told ESPN: "Wow.
"These are the most deserving players I've ever seen, they played with such heart and such desire."
The city's recovery from the bomb attacks which hit April's Boston Marathon was a recurring theme at the presentation, with Henry's co-owner Tom Werner adding: "We pay tribute tonight to all the families who suffered through the marathon bombings. This city showed great strength to battle back."
Second baseman Dustin Pedroia added that the team "wanted to do something special and make this city proud of the team in the toughest of times", but it was left to series MVP Ortiz to sum up feelings on the subject.
Ortiz memorably paid tribute to the city's law enforcement officers at a game against the Kansas City Royals days after the bombing and, handed the microphone again at the trophy presentation, the slugger known as 'Big Papi' jokingly recalled his strongly-worded message of defiance.
"Should I keep it clean?," he asked, before adding: "This is our - beeeep - city!
"I want to say: This is for you, Boston. You guys deserve it. We've been through a lot this year and for all of you and the families who struggled with the bombing earlier this year - this is for you.
"I want to thank God. We had a tough time, with the situation we all went through, and thanks to Him we kept ourselves together and here we are enjoying this time.
"I want to thank the best fans in the world. I'm so proud to play for this city.
"I want to thank my team-mates - you guys are legit. I knew it was going to be a special year and when we started rolling, nobody ever stopped the train."
Team manager John Farrell, reflecting on the six-game battle for the title, said: "I'd like to congratuate (manager) Mike Matheny and the St Louis Cardinals on a great series.
"We played against a great team and (wish them) all the best going forward.
"To all these guys in uniform, to see the work they put in and to share this with the greatest fans in the world, it's a special night."
