Summoned in a tough spot, Royals rookie Brandon Finnegan trotted in from the bullpen, threw his warmup pitches and then did something curious. With a rollicking crowd at AT&T Park ready to erupt, Finnegan made it all look routine. Only four months after he pitched in the College World Series, the 21-year-old lefty got two key outs in the seventh inning and helped Kansas City hold off the San Francisco Giants 3-2 on Friday night to take a 2-1 edge. Just like that, the Royals were halfway to the championship, boosted by a dominant bullpen, several nice defensive plays and barely enough hitting.
