ATP - Top 15 Americans
Notable Changes
- Sam Querrey reclaims the No. 2 spot by reaching the semifinals of ATP Memphis.
- Despite dropping a spot, Stevie Johnson continues his strong 2015 campaign with back to back quarterfinal showings at Memphis and Delray Beach Open.
- Donald Young continues his rise with a semifinal at Memphis and second career ATP final at Delray Beach Open (l. Karlovic).
- Also in Memphis, Austin Krajicek reached first career ATP quarterfinal losing to top seed, Kei Nishikori, in 3 sets.
- Ryan Harrison jumps 56 spots since the last monthly ranking. The 22 year old qualified and made the semifinals of ATP Acapulco, a 500 level tournament. Along the way, he defeated Young, Grigor Dimitrov (1st Top 10 win in 23 tries), and Ivo Karlovic before falling to World No. 9 David Ferrer who went on to capture the title. Harrison attributes his resurgence to the rehiring of coach Grant Doyle and the mentorship of Andy Roddick.
