premise: Cloyd Victor Boyer Jr. (born September 1, 1927) is a former right-handed pitcher and pitching coach in Major League Baseball who played between 1949 and 1955 for the St. Louis Cardinals (1949–52) and Kansas City Athletics (1955). He was born in Alba, Missouri. Boyer is the older brother of star major league third basemen Ken Boyer (1931–1982) and Clete Boyer (1937–2007).
hypothesis: Clete Boyer is a former right-handed pitcher and pitching coach in Major League Baseball who played between 1949 and 1955 for the St. Louis Cardinals.
reason: Cloyd Victor Boyer Jr. fits the description of my statement per the context, not his brother Ken. The system failed to see that I switched the bothers and their careers around.
