Robert William "Red" Thomas (April 25, 1898 – March 22, 1962) was a center fielder in Major League Baseball.

In 1919, he joined a professional team in Little Rock, Arkansas that was part of minor league baseball's Southern Association.

Thomas' single in the last inning of the initial contest sent two runs home for a victory, and he started the rally in the last inning of the second contest with a double, and scored on a single...."[7]Interviewed in 1927 for a Fremont Messenger article, Thomas described his initial experience with the Cubs: "When I appeared on the field for my first major league game against Brooklyn I was the proudest fellow in the land.

According to the September 1, 2022 edition of The Springfield News: "Red Thomas ... center fielder with the Hens, who had a fling ... in the National league last season, when he was sold to the Chicago Cubs, had more to do with the victory than any other member of [the Henryetta] crew.

In addition to this, he made six nice catches in deep center field.... [After] a relief hurler [was called in] in the seventh inning and ... allowed but one hit ... 'Red' Thomas decided to connect for his home run....

The little guardian ... who went to Henryetta when Foster came here as manager of the Midgets, opened the first inning with a hard blow to center field for three bases.

Thomas drove out a horn run in the seventh inning to make the final Hen score.

Even though he hit .315 there, he was traded to the minor league team in Augusta, Georgia as part of a five-player deal, but still found no job security.
