Fognini notched his first ATP championship a week ago in Stuttgart and Sunday fought off three match points before winning the German Tennis Championships. That lifted him to No. 19 in the rankings.
He defeated qualifier Federico Delbonis in the Hamburg final, ending an impressive run by Delbonis. After winning two matches to qualify, Delbonis moved through the main draw, notably beating world No. 5 Roger Federer in the semifinals Saturday. He goes from 114th to No. 65 in the rankings.
Ivo Karlovic beat Alejandro Falla in the final at the Claro Open Colombia, Falla's home country. Karlovic returned last week after missing two months of play due to viral meningitis. The win in Colombia marked his fifth ATP title but first since June 2008. His first four titles came within a 14-month span.
He's up 68 places this week to 87th.
Falla also makes a substantial move up, getting to No. 83 after starting last week at 122nd.
There were no changes in the Top 10. Federer was the only player from the top tier in action.
