Bautista Agut played a great match against Rublev and hit the Russian's corners better. Yet, the few close misses when Rublev sidestepped to his forehand aiming for Agut's backhand corner seemed as a hangover from the Russian's doubles' competition. In the second set alone, in some crucial moments Rublev put about 4-5 balls out, which were in the doubles area ok, at Agut's backhand side. So, were those unforced errors a hangover from the Russian's doubles matches? Can playing doubles be detrimental for the singles?
