Rivalries grow in time, creating history, unique memories and storylines that extend beyond the current season.

The Chiba Jets-Yokohama B-Corsairs rivalry is all of two games, but already it's an intense one, as evidenced by the bj-league expansion teams' hard-nosed competition over the weekend at Funabashi Arena.

Yokohama, gritty, athletic and fast, bounced back from a series-opening loss and earned a series split, winning Sunday's rematch 81-61 before a lively crowd of 1,579.
