Roger Federer’s retention of the No. 1 spot in the rankings headlined an otherwise slow week in the ATP rankings on Monday.

The only significant move inside the Top 20 came from Spain’s Marcel Granollers moving up four spots to No. 20 following his trip to the finals at Umag last week.

It’s a career-best ranking for Granollers, who was just 12-14 entering the Croatian field a week ago. The ascension also gives Spain a staggering five players ranked in the Top 20.

Colombia’s Alejandro Falla entered the Top 50 for the first time on Monday, following his win at Bogota on clay. He rose 10 spots to No. 48.

Plummeting the other direction was former No. 1 Juan Carlos Ferrero, who fell 19 spots to No. 56 after a first-round flameout at Umag against Croatia’s No. 547 Mate Pavic. Ferrero last appeared in the Top 10 in August of 2004.

There were few changes atop the WTA rankings either in the week after Wimbledon.

Slovaki’s Dominka Cilbukoa slipped past Russia’s Maria Kirilenko to take back No. 14 in the world, and Sabine Lisicki, Andrea Petkovic and Jelena Jankovic all moved past Flavia Pennetta, who dropped from 17th to 20th.

The Top 100’s biggest move came from 21-year-old American Coco Vandeweghe, who took an enormous step forward in her career, soaring from 120th to 69th by reaching the finals of the Bank of the West Classic at Stanford, where she lost to No. 4 Serena Williams.

Vandeweghe is quietly having an impressive season, now 32-18 on the year, even though most of her wins have come in ITF competition -- reaching the finals at Nottingham the week before Wimbledon, with wins over three players ranked between 64th and 81st.
