Nadal won in Barcelona and since it was a title defense he didn't improve his ranking and remains No. 5. Rosol scored his first ATP tournament victory in Bucharest and moved up to 35th.
Rosol grabbed headlines last summer when he posted a huge upset over Nadal in the second round at the Wimbledon Championships. That match turned out to be the last for Nadal until this February's tournament in Chile.
Since beating Nadal, Rosol was just 14-13 in ATP main draws until last week when he swept through the Bucharest field.
Since his return Nadal is 26-2 -- both losses in finals -- and Sunday defeated Nicolas Almagro for his fourth championship of 2013 and 54th overall. It was his 39th on clay, which is third-most all-time -- one behind Thomas Muster and six off the record held by Guillermo Villas.
Novak Djokovic is No. 1 for a 79th week overall. That's 10th most all-time and he'll catch No. 9 Lleyton Hewitt next Monday. Djokovic has 12,900 points, more than 4,000 ahead of No. 2-ranked Roger Federer.
Tipsarevic is the top seed at the BMW Open this week. Ferrer is seeded first in Portugal.
