They also lost in the quarterfinals at both Winston-Salem and the US Open, the latter to top seeds and defending champions Juan Sebastián Cabal and Robert Farah. Their next tournament was in Metz, where they lost to eventual champions Struff and Robert Lindstedt in the first round. Again they were on the wrong end of a huge tie-break, losing 4–6, 6–7(15) on Struff and Lindstedt's fifth match point. A run of first and second round losses continued for the next month, their last event together for 2019 being in Vienna, where they had to qualify before eventually losing in the quarterfinals to Rajeev Ram and Joe Salisbury, the latter going on to defend the title he had won the previous year with Neal Skupski.
