For a professional sports team, playing better in a season's late stages is more important than doing so at the beginning.

The expansion Yokohama B-Corsairs are doing precisely that, making improvements that enable them to play their best ball when it matters most and be a factor in the hunt for a title.

The B-Corsairs extended their winning streak to seven games, beating the Sendai 89ers 63-54 on Saturday at Hiratsuka Gymnasium.
