Royals manager Ned Yost announced Tuesday before Game 1 in Kansas City against the San Francisco Giants that right-hander Jeremy Guthrie will start Game 3 and left-hander Jason Vargas will pitch Game 4 on Saturday and Sunday in San Francisco. - - The Royals made a minor last-minute change to their World Series roster before Game 1 on Tuesday, adding Jayson Nix in place of Christian Colon. The swap of utility players is the only alteration to the Royals' roster from the American League Championship Series. - - The Philadelphia Phillies signed right-hander Jerome Williams on Tuesday to a one-year, $2.15 million contract for 2015 that could be worth up to $4 million with incentives. The Phillies claimed Williams off waivers in August after he struggled with the Houston Astros and Texas Rangers. (Editing by Frank Pingue)
