Tommy Paul won a two-day match in Hamburg that required saving seven match points, then later reached the semifinals there alongside Aleksandar Kovacevic. The Hamburg run kept Paul alive deep in the tournament and put Kovacevic in the mix as the first American duo to reach the last four there since Pete Sampras in 1995. Ignacio Buse then went on to beat Paul for the Hamburg title, while Learner Tien won the Geneva trophy over Mariano Navone.
