OAKLAND, Calif. — Don Nelson had one message for Baron Davis at the morning shootaround: "dominate."

Davis had no problem obliging, despite the Dallas Mavericks' increased, more intense defensive pressure as they attempted to save face in their first-round playoff series with the Warriors.

Instead, the top-seeded Mavs are on the brink of an embarrassing early exit at the hands of eighth-seeded Golden State after a 103-99 loss Sunday night in Game 4 that gave the Warriors a commanding 3-1 lead in the best-of-seven series.

If Golden State can pull off the upset, the Warriors would join only the Denver Nuggets (1994) and the New York Knicks (1999) as teams that have won a playoff series as a No. 8 seed.

In other NBA playoff games Sunday, Chicago defeated defending champion Miami 92-79 to complete a sweep of their first-round series, Phoenix beat the Los Angeles Lakers 113-100 to a take a 3-1 series lead, and New Jersey routed Toronto 102-81 to go up 3-1.
