Spain's Tommy Robredo jumped 29 spots in the rankings up to No. 43 in the world thanks to his tournament victory at Casablanca on Sunday.
The 30-year-old Robredo, at one time ranked No. 5 in the world, beat three players ranked higher than him in taking the tournament title, his first since winning Santiago in 2011 and his 11th overall - 10 of which have come on clay.
The last time Robredo was ranked this high was August of 2011.
Robredo's move into the top 50 was the only big jump in a ho-hum week as things gear up for the larger clay court tournaments.
At the other end of the spectrum, Spain's Pablo Andujar plummeted 39 spots to No. 96 after losing in the first round of Casblanca a year after winning the event.

The Czech Republic's Klara Zakopalova joined the WTA top 20 for the first time on Monday, following her second-round appearance at Katowice and fourth-round appearance at Miami in March.
Kakopalova climbed over Clara Suarez Navarro, who fell four spots this week.
All other changes in the women's Top 50 were minor.
