SAN FRANCISCO-Facing a possible 3-1 hole, the San Francisco Giants refused to give up and because of it, the 110th World Series is all tied up.

Pablo Sandoval hit a two-run single in the bottom of the sixth inning, as the Giants scored three runs in the inning on their way to a 11-4 victory over the Kansas City Royals before a sellout crowd of 43,066 at AT&T Park in Game Four of the World Series.

Brandon Belt then singled up the middle for the third run of the inning, and the Giants never looked back on this game.

Joaquin Arias led off the inning with a pinch-hit single while hitting for Yusmeiro Petit, then Gregor Blanco singled, before Joe Panik sacrificed the two an additional 90 feet and then Brandon Finnegan intentionally walked Buster Posey to load the bases.

Pence then grounded into a force play that retired Arias at home plate, and then Sandoval broke up the tie with his single to centerfield.

The Giants took a quick 1-0 lead in the top of the first inning, Blanco walked, went to second on a Jason Vargas wild pitch, then stole third and after a Posey walk, Pence grounded into a fielders’ choice to score Blanco.

The Royals took the lead in the top of the third inning, as they scored four runs, as Ryan Vogelsong was unable to make it of the inning.

Vargas led off the inning with a fly out to Blanco, then Alcides Escobar got the rally started with a single, but was forced out at second base on a ground ball by Alex Gordon.

With Lorenzo Cain at the plate, Gordon stole second base and then scored the tying run, when Erik Hosmer singled just beyond first base.

After a Mike Moustakas walk, Omar Infante singled thru the infield into centerfield to score Cain and Hosmer.

Salvador Perez then also singled to centerfield to score Moustakas and that was the end of the night for Vogelsong.

Jean Machi replaced Vogelsong, and promptly walked Jarrod Dyson; however he was able to get out of the inning by striking out Vargas.

The Giants cut the lead in half in the bottom of the frame, as Matt Duffy singled while batting for Machi, went to second on a Blanco groundout, then after Panik flew out for the second out of the inning, Posey singled to left and that was followed by a Pence single; however Vargas struck out Sandoval swinging to end the inning.

Petit, who entered the game going 5-for-103 at the plate in his career, singled to centerfield with two out in the bottom of the fourth inning.

Panik began the Giants rally in the bottom of the fifth inning as he doubled off of Vargas, which turned out to be Vargas’ last pitch of the night.

Jason Frasor then came on for Vargas, and after a Posey groundout, Pence cut the Royals lead down to 4-3.

Juan Perez tied up the game when hit a sacrifice fly to score Pence with the tying run, and both starting pitchers were off the hook.

Vogelsong went 2.2 innings, allowing three runs on six hits, while walking two and striking out three.

Vargas went four innings, allowing four rubs on seven hits, walking just one and striking out two in his first World Series start.

Petit continues to be masterful in the postseason, as he pitched three innings allowing two hits and a walk.

During the postseason, Petit extends his scoreless streak to 12, allowing just four hits, while walking four and striking out 13.

Jeremy Affeldt pitched one inning, and extended his scoreless inning streak up to 21, moving into second place all-time behind Mariano Rivera, who pitched 23 scoreless for the New York Yankees.

There were no home runs for the second consecutive game, as this was the first time since Games Two and Three of the 2012 World Series, which was the Giants and the Detroit Tigers.

Prior to that, the last time it happened was in Games 2, 5, and 6 of the 1996 World Series between the New York Yankees and the Atlanta Braves.
