The San Francisco Giants brought Kansas City Royals' perfect postseason to a shuddering end with an emphatic 7-1 win in the opening game of the World Series.
Giants ace Madison Bumgarner delivered a sparkling seven innings of work and Hunter Pence slammed a first inning two-run homer that pushed the Royals into an early hole they were unable to claw out of at their Kauffman stadium home.
With the Royals back in the Fall Classic for the first time in 29 years, fans arrived early and filled the stadium ready to party and watch their team add to an unbeaten 8-0 playoff run.
But the Giants, bidding for a third title in five years, played party poopers by snapping an 11-game Royals postseason winning streak that stretches back to their 1985 World Series triumph.
Game Two of the best-of-seven series is set for Wednesday (local time) in Kansas City.
Making his first start since the American League championship series opener on October 10, rusty Royals righty James Shield could not find his rhythm and laboured through three plus innings in which he was pounded for five runs on seven hits.
In contrast, Bumgarner, the Most Valuable Player in the National League championship series, was dominant.
The big lefty putting himself into contention for similar MVP honours in the World Series by surrendering just one run on three hits, striking out five and walking one.
The Giants were quick out of the blocks in tagging a shaky Shields for five hits in the opening inning, including a line drive two-run shot from Pence and an RBI double from Pablo Sandoval to jump in front 3-0 and quieten the capacity crowd.
The Royals had the stadium rocking again in the bottom of the third when they loaded the bases but Bumgarner worked his way out of the jam and got Lorenzo Cain to ground out to end the threat.
Pence led off the fourth with a double and scored on a line drive single to centre from Michael Morse that chased an ineffective Shields from the game.
Reliever Danny Duffy issued a bases loaded walk to Gregor Blanco to push across another Giants run as the NL champions went up 5-0.
The Giants added to their advantage in the seventh with Joe Panik and Sandoval driving in runs before Kansas City finally got on the scoreboard in the bottom of inning.
Salvador Perez took Bumgarner over the wall in leftfield, the solo shot ending the lefthander's Major League Baseball postseason record of 32.2 scoreless innings pitched on the road.
