As bouncers rolled by infielders and bloops dropped in front of outfielders, it became clear this World Series was headed to a climactic Game 7 - just like the one 29 years ago when the Kansas City Royals won their only title. Lorenzo Cain looped a two-run single - one of eight Royals to get hits in a seven-run second inning - and Eric Hosmer chopped a two-run double over shortstop as the Royals battered the San Francisco Giants 10-0 Tuesday night to tie the Series at three games apiece. Pitching with the initials of late St. Louis outfielder Oscar Taveras on his cap, 23-year-old rookie Yordano Ventura allowed three hits over seven innings for his first Series win. Jeremy Guthrie starts Wednesday night for Kansas City and Tim Hudson for San Francisco in a rematch of Game 3, won by Kansas City 3-2.
