Chicago Cubs free-agent signing Shota Imanaga couldn't have drawn up a better start to his MLB career. The Japanese pitcher chalked up another scoreless start on Saturday, tossing five 1/3 innings with four strikeouts to pick up his second win of the season. Imanaga's outing against the Seattle Mariners marks the first time since at least 1913 that a Cubs hurler went four-plus innings and did not allow an earned run in each of his first three career games.
