Consider the Shannon twins, Joe and Red. On Oct. 7, 1915, 18-year-old Joe played his fifth game in the majors, logging a few innings at second base for the Boston Braves. His double-play partner? Brother Red, who was making his MLB debut. Red Shannon would play parts of seven seasons through 1926, but Joe never made it back to the majors.

Wednesday was moving day for the Rogers twins, as both Taylor and Tyler were dealt ahead of the MLB trade deadline. First up, Taylor Rogers was dealt from the Cincinnati Reds, along with shortstop prospect Sammy Stafura, to the Pittsburgh Pirates in exchange for third baseman Ke'Bryan Hayes.

The Chicago Cubs may not have made a big splash at the trade deadline, after missing out on Eugenio Suarez and failing to acquire another starting pitcher other than Mike Soroka. However, they added multiple pieces to the roster and snuck one final trade in before the trade deadline passed.
