Stanley Cayasso

Oliver Stanley Livingstone Cayasso Guerrero (September 17, 1906 – August 4, 1986) was a Nicaraguan baseball player active from the 1930s to the 1950s. Along with Dennis Martínez, he is commonly cited as one of the best Nicaraguan baseball players of all time.

Born in Bluefields in eastern Nicaragua, Cayasso's "Navy" team played a barnstorming tour of the country's Pacific coast in the early 1930s, which is cited as the catalyst for baseball's popularity in the country. Cayasso played the 1933 season for Managua, and later joined the "General Somoza" club, named after the country's dictator Anastasio Somoza García. In 1941, he joined the Cinco Estrellas club; technically part of the Nicaraguan National Guard, Cayasso's on-field performance saw him promoted to the rank of lieutenant. The former national stadium of Nicaragua, built in 1948, was renamed the Estadio Stanley Cayasso in 2018, after the construction of the nearby Estadio Nacional Dennis Martínez. Connie Marrero, who faced Cayasso in the Amateur World Series, commented that "I am sure that Cayasso would have been a bright light in whatever league. He is the best Nicaraguan player that I have seen."
