Left-handed pitcher Rube Marquard of the Giants won 19 decisions in a row to start the 1912 season. This tied a single-season mark set by Tim Keefe in 1888 and remains a record that stands to this day. Marquard’s first loss of the season came on July 8th, when the Cubs defeated New York, 7-2. Marquard went on to win a total of 26 decisions for the season, helping the Giants on their way to winning the NL pennant.
