Five key moments from the Giants' 7-1 win over the Royals in World Series Game 1

The World Series' return to Kansas City wasn't nearly as happy as Royals fans were hoping. The San Francisco Giants routed the Royals in Game 1 of the World Series, winning the game 7-1 and snapping K.C.'s eight-game winning streak this postseason.

Madison Bumgarner turned in another dominating playoff performance, pitching seven innings of three-hit ball. The Giants jumped on Royals starter James Shields early, scoring three in the first inning. Pablo Sandoval and Hunter Pence each had two hits and two RBIs for the Giants. The Kauffman Stadium crowd, loud and happy at the start, ended the night disappointed.

Here are five key moments from Game 1:

1. HUNTER PENCE'S FIRST INNING HOMER
Hunter Pence hadn't homered in the 2014 postseason, but he quickly changed that in Game 1 of the World Series, taking Shields deep in the first inning. The homer also scored Pablo Sandoval, who had just doubled in a run. Pence's two-run homer put the Giants up 3-0.

2. MADISON BUMGARNER WIGGLES OUT OF THE THIRD
The third inning was the only time the Royals mounted anything resembling a rally against Bumgarner. Omar Infante reached on an error to start the inning. Mike Moustakas followed with a double. Bumgarner then struck out the next two batters. He then walked Lorenzo Cain, loading the bases for Eric Hosmer. Kauffman Stadium was wishing it could come unglued by a big hit, but Hosmer bounced out to second base.

3. DANNY DUFFY COMES IN AND WALKS IN A RUN
The Royals called on Danny Duffy in the fourth inning, once Shields was lifted. Duffy was one of their best starters in the regular season, but had pitched only one inning as a reliever in the postseason. He had some late-season injury concerns. Anyhow, Duffy came in with two runners on. After a Juan Perez sacrifice bunt, Duffy walked Brandon Crawford to load the bases, then he walked Gregor Blanco to bring home a run. That made the score 5-0 and pretty much spelled the end for the Royals.

4. JOE PANIK DOES IT AGAIN
Rookie Joe Panik came through with another big hit for the Giants. In the seventh, with Blanco on first, Panik tripled past a diving/tumbling/falling Nori Aoki in right field. It was Panik's 12th hit and sixth RBI of the postseason. Not bad for a 23-year-old.

5. SALVADOR PEREZ GETS THE ROYALS ON THE BOARD
Salvador Perez — the sweet-smelling Royals catcher — got K.C. its first run of the World Series. It was too little, too late, but this post could use a Royals highlight, couldn't it? Perez took Bumgarner deep in the seventh inning for a solo homer that made the score 7-1.
