Miami - Russia put four women into the third round of the Miami Masters on Friday, with second seed Dinara Safina leading the way past France's Mathilde Johansson 6-1, 6-3.
Safina, who missed a chance to seize the number 1 WTA ranking from Serena Williams last week in Indian Wells when the American did not play, paced fourth-seeded compatriot Elena Dementieva, a winner over Anastasia Pivovarova 6-0, 3-6, 6-3.
