Ishikawa hit a walk-off three-run home run Thursday to win Game 5 of the NLCS and send the Giants to the World Series. It is the first home run to end an NLCS and fourth to end an LCS. Ishikawa started the year with the Pirates before being designated for assignment in mid-April. The Giants signed him to a minor-league deal but did not call him up from Triple-A until late July. Ishikawa jumped on a 2-0 fastball from St. Louis' Michael Wacha and sent it into the right-field seats.
