Lewis Sidney Riggs (April 22, 1910 – August 12, 1975) was an American third baseman for the St. Louis Cardinals (1934), Cincinnati Reds (1935–40), and Brooklyn Dodgers (1941–42 and 1946).

His eighth-inning pinch single off Red Ruffing scored teammate Cookie Lavagetto in the opening game of the 1941 World Series, before Ruffing and the New York Yankees held on for a 3-2 victory.

Riggs never quite achieved the same level in his baseball career after leaving the Dodgers in 1942 in order to serve his country in the Army Air Force during World War II.

In 10 seasons he played in 760 Games and had 2,477 At Bats, 298 Runs, 650 Hits, 110 Doubles, 43 Triples, 28 Home Runs, 271 RBI, 22 Stolen Bases, 181 Walks, .262 Batting Average, .317 On-base percentage, .375 Slugging Percentage, 930 Total Bases and 37 Sacrifice Hits.
