The baseball team fielded by Captain Solok from the all-Vulcan crew of the USS T'Kumbra, formed to prove Vulcan superiority over Benjamin Sisko at his own favourite game.
The Logicians are the opponents of the Niners in the Deep Space Nine episode Take Me Out to the Holosuite. They are drawn from the crew of the USS T'Kumbra, a Starfleet ship staffed entirely by Vulcans, which puts in at the station for repairs.
Their captain, Solok, has needled Sisko since their Academy days, when he beat him in a wrestling match and went on to cite the incident in papers on the limits of emotional species. Having learned baseball precisely because Sisko loves it, he arrives with a drilled team that is faster and stronger than its rivals.
The Logicians win easily, ten to one. Solok is nevertheless left baffled and irritated when the losing side toasts its one run as a triumph, and is ejected by the umpire Odo for touching him.
