Sandoval's hit off of Reds reliever Sam LeCure snapped a tie with Willie Mays for the all-time San Francisco Giants record and leaves Sandoval one game behind Johnny Rucker's franchise streak of 18 games that began the New York Giants' 1945 season. Alvin Dark had also hit in 16 straight games to begin the 1954 season.
Sandoval scored ahead of Buster Posey when Posey hit a home run to right field to account for the Giants' only runs.
Sandoval was 0-for-2 going into the ninth despite hitting the ball well his first two times at the plate. He flew out to center in the first inning and then to left leading off the third inning. He worked a walk with a nine-pitch at-bat in the sixth inning after falling behind, 0-2.
Sandoval had four RBIs as part of a 3-for-9 day in a doubleheader against the Mets on Monday. He is now hitting .333 for the season, with a team-high 23 hits and 13 RBIs.
"We were happy for Pablo," said Giants manager Bruce Bochy.
