Lukas basically is mediocre in general, and on clay he's a disaster, like fellow Slovak Beck. Hrbaty was average on clay also. Frank obviously isn't a clay player, but his mentality was probably better here while Lacko I'm guessing gave no effort.
Stop the hate, brotha. Lacko is a shotmaker and a pretty decent one, Top50 potential so this is a pretty bad defeat. This is RG, not some challenger in the middle of nowhere.
Dancevic is in decent form but he is barely Top100 with his game, as aesthetic as it may be.
