I'm a Royals fan and wouldn't want to see it, but I think, if I'm SF, I start Bum and let him go as long as he is effective. For them, the strategy has to be to shut the Royals down for three or four inning, get the lead, and hold it into the seventh. Personally, I'm giddy over the Guthrie/Hudson matchup. I think that by the time the Giants get around to using Bumgarner, it may be too late. If I'm the Royals, though, I don't start Shields. Right now, Guthrie is as good as or better than Shields in this spot.
