( CNN ) -- Fending off elimination for the third straight game , the San Francisco Giants thrashed the St. Louis Cardinals on Monday night to earn the right to battle for their second World Series title in three years . The Giants beat the Cardinals 9-0 Monday in a game that lacked the drama of some of the other games during the highly competitive series . San Francisco had been on the brink since last Thursday , when St. Louis jumped to a three games to one advantage in the best-of-seven National League Championship Series . But San Francisco has been on a roll since -- beating the Cardinals twice by five-run margins , before finishing off the reigning champs in convincing fashion Monday at AT & T Park , the northern California team 's home . With the victory , the Giants earned the right to face the Detroit Tigers in the World Series , which begins Wednesday . The Tigers handily swept the New York Yankees last week to become American League titlists and earn their shot at baseball 's top prize . On Monday night , San Francisco used the same formula that 's worked for them so well in recent days : timely hitting and exceptional pitching . Matt Cain was stellar on the mound , pitching 5 and 2/3 scoreless innings to start the game . He even helped his cause at the plate with a run-scoring single in the second inning . The next frame , the Giants exploded for five runs to build a comfortable 7-0 lead . They never looked back , fending off a St. Louis rally in the sixth inning and tacking on more runs in the seventh and eighth innings . Monday 's win also marked the second furious comeback the Giants had completed during the postseason . The team was able to come back from a 2-0 deficit and win a best-of-five series against the Cincinati Reds earlier in the playoffs . `` They did n't want to go home . They kept believing , '' said Giants manager Bruce Bochy . Giants catcher Buster Posey said it is the team 's attitude that helps them beat the odds . `` It is a lot of want and a lot of will power , '' Posey told reporters . `` You have to believe you can do it . '' The Giants easily finished the regular season atop the National League West with a 94-68 record , tied with Atlanta for fourth best in the league . Detroit , meanwhile , had an 88-74 mark in pulling past the Chicago White Sox in the final month to earn a ticket to the playoffs . That said , while their record is inferior , the Tigers feature two of the biggest weapons in baseball in pitcher and 2011 American League MVP Justin Verlander and this year 's Triple Crown winner Miguel Cabrera .
St. Louis led the National League series 3-1 just a few days ago . The Cardinals have won three of four games against the Cubs this season, including two in extra innings. They 'll face the Detroit Tigers , led by Justin Verlander and Miguel Cabrera .
