The Nagoya Diamond Dolphins have opened the new season with a strong overall showing over the first three weeks.

Second-year coach Reggie Geary's team has won four straight games and shares the league lead for the best record (5-1) through Sunday. Four other teams — the Alvark Tokyo, Tochigi Brex, Sunrockers Shibuya and San-en NeoPhoenix — have identical records.

Geary credits his team's solid defense as a key element in its success to date.
