Luis Alomá Barba (June 19, 1923 – April 7, 1997), nicknamed "Witto", was a Cuban-born relief pitcher in Major League Baseball who played for the Chicago White Sox from 1950 through 1953.

In 1947 Alomá split the season between the Lookouts and the Class B Charlotte Hornets of the Tri-State League.

He spent his last year in the Senators' farm system playing for his home town team, Havana Cubans of the Florida International League.

Alomá was again traded, this time on August 5, 1949, from the Tigers to Chicago White Sox in exchange for pitcher Alex Carrasquel.

Alomá was 26 years old when he broke into the big leagues on April 19, 1950, with the White Sox.

On June 17, he received a spot start due to a packed White Sox schedule (seven games in four days) and shut out the Philadelphia Athletics on five hits.

In 1954, Alomá spent his entire season with the Double-A Memphis Chickasaws of the Southern Association.
