Rafael Nadal reached his seventh consecutive final since returning from a knee injury, brushing aside wild-card entry Pablo Andujar, 6-0, 6-4, Saturday at the Madrid Open. Nadal had little trouble extending his winning streak in clay-court semifinals to 46 matches, quickly finishing his overmatched countryman from Spain. Nadal can win his fifth title since coming back from a seven-month layoff while recovering from a knee injury. He will play Stanislas Wawrinka, who beat Tomas Berdych, 6-3, 4-6, 6-4. Serena Williams and Maria Sharapova will meet for the No. 1 ranking and the women’s title after cruising in their semifinals. The top-ranked Williams will have a chance to win her 50th title after beating Sara Errani, 7-5, 6-2. No. 2 Sharapova got her 500th win by defeating Ana Ivanovic, 6-4, 6-3.
