Kansas City manager Ned Yost is expecting pitching ace James Shields to bounce back Sunday when he takes the mound for the Royals in game five of the World Series. Shields' career post-season earned-run-average rose to 5.74 after he gave up five runs in three-plus innings against San Francisco in the first game of Major League Baseball's championship final on Tuesday. It was another sub-par playoff performance from Shields, who came off a stellar regular season in which he built a 14-8 record with a 3.21 ERA.
