William Lamar Bethea (born January 1, 1942), nicknamed "Spot", is an American former professional baseball player who appeared in ten games in the Major Leagues as an infielder for the 1964 Minnesota Twins.

The native of Houston threw and batted right-handed, stood 6 feet (1.8 m) tall and weighed 175 pounds (79 kg).

Originally signed by the St. Louis Cardinals in 1963, Bethea batted .371 in the Pioneer League (then Class A) that season and was selected by the Twins in the first-year player draft then in effect.

In his first MLB at bat (in his fourth game played), on September 20, 1964, at Fenway Park, Bethea doubled off Ed Connolly of the Boston Red Sox, driving home Bob Allison from first base for his first run batted in in the Majors.

[1] In his brief big-league trial, however, Bethea collected only five total hits and two RBI in ten games played and 30 at bats.
