Jason Vargas, Royals
Against the Giants
2014: 1 GS, 0-0, 3.60 ERA
Career: 3 GS, 0-1, 3.15 ERA
Loves to face: Michael Morse, 3-for-13, 4 K
Hates to face: Pablo Sandoval, 3-for-9, 1 BB
Why he'll win: Southpaw Vargas thrived away from Kauffman Stadium during the regular season, posting a 2.73 ERA in 14 road starts.
Pitcher beware: This is his first career appearance at AT&T Park, and it's been 10 days since his last start.
Bottom line: In his first two postseason starts, Vargas did precisely what the Royals asked of him: He got Kansas City into at least the sixth inning tied or in the lead. Expect the same on Saturday.
Ryan Vogelsong, Giants
Against the Royals
2014: Did not face the Royals
Career: 0 GS, 0-0, 18.00 ERA
Hates to face: Omar Infante, 7-for-11
Why he'll win: Whereas Vargas enjoyed his 2014 road starts, Vogelsong excelled at home. He had a 3.06 ERA at AT&T Park (compared with 5.10 on the road), and just two of the 18 regular-season homers he allowed were hit in San Francisco.
Pitcher beware: Vogelsong was hit hard in his most recent start, against the Cardinals, allowing four runs on seven hits in three innings. The task does not get any easier against a Royals offense that has been on point in the postseason.
Bottom line: Vogelsong and the majority of the players in the Royals' lineup are completely foreign to each other. Who can make quick adjustments to this dual unknown will be the determinant here.
