Corey Seager has been playing baseball of some sort since 1997, and Saturday night marked a surprising first for the Dodgers star. When Seager's ball eluded left fielder Scooter Gennett in the bottom of the ninth inning for a run-scoring double, it gave Los Angeles a 5-4 victory over the Cincinnati Reds - and a new accomplishment for Seager. ''No high school, no summer ball, no minor leagues, no nothing,'' Seager said.
