This "two appearances since 2013" may be written in the rules, but I refuse to believe it.
Yes crazy how basically every former DC singles player is so far behind their best right now and therefore no serious option (Mayer, Gojowczyk, Haas, Brands, Struff, Becker, Kamke).
Hopefully you're right.
It's crazy how many Top 100 Player are or were struggling with injuries or bad form. Mischa Zverev is another one. But in some cases it has to do with age.
The Davis Cup squad is nice.
