Charles William Smith (September 15, 1937 – November 29, 1994) was an American professional baseball third baseman.

In his first start of 1961, Smith took the St. Louis Cardinals' Curt Simmons to left center field for his first major league home run.

[2] He made his first major league start at short in the second game of an April 30 doubleheader with the Chicago Cubs, and committed a throwing error.

[3] Twenty games into the 1961 season, the Dodgers traded Smith and outfielder Don Demeter to the Philadelphia Phillies for relief pitcher Turk Farrell and infielder Joe Koppe.

During the off season, he and pitcher John Buzhardt were traded to the Chicago White Sox for slugging first baseman Roy Sievers.

Two games into the 1964 season, Smith was dealt to the New York Mets for shortstop Chico Fernández and minor league catcher Bobby Catton.

Though he went hitless in his first 25 at bats as a Met, Hall of Fame manager Casey Stengel stuck with Smith, and he soon emerged as the top slugger on the team.

His glove also improved substantially; he only made eighteen errors at third for a .957 fielding percentage (league average was .951).

After the season, he and pitcher Al Jackson were traded to the Cardinals for former National League Most Valuable Players Ken Boyer.

His performance was good enough to catch the eye of New York Yankees General Manager Lee MacPhail, who traded Roger Maris for Smith in a one-for-one swap on December 8, 1966.

[13] A little over a week before acquiring Smith, the Yankees traded away 1966 starting third baseman Clete Boyer.

Smith became a reserve, making just 77 plate appearances, and received most of his playing time as a pinch hitter.
