For "highest level of his sport", tennis gets messy as there are multiple levels of professional tours.   represents the the consensus for cut-off with respect to what competing at the highest level means.  Mertl has not made an appearance in the main draw of any Grand Slam event. http://www.atpworldtour.com/Tennis/Players/Me/J/Jan-Mertl.aspx?t=pa&y=0&m=s&e=gs# This summary shows that he has competed in the qualifiers and got as far as the third round in the 2008 Australian Open before losing.  Nor is there any other indication of competing the world tour event main draws.  As for the ATP Challenger series, he has not won at title in that tour, and the remaininf competition appear to be part of the ITF Futures which isn't sufficiently high level
