Guillermo Quiroz hit a pinch-hit, walk-off home run for the San Francisco Giants against the Los Angeles Dodgers on Saturday, the team's first in a long time.
Armando Rios was the last player to accomplish the feat for the Giants. He did so on July 18, 2000.
Quiroz had not played since April 24 and never had a walk-off hit in the Majors.
