Former No. 1, Grand Slam champion, ex-Adam Scott squeeze and Sports Illustrated swimsuit model Ana Ivanovic made an inauspicious debut on Twitter this week, when her social media debut consisted of a single letter.

With that post — if you can call it that — and the blue check mark that later accompanied her name, Ivanovic became one of the last WTA holdouts to join Twitter. Ben Rothenberg of the New York Times notes that Sam Stosur is the only top-20 player now without an account.

That “a” post was taken down Thursday night, soon after Ivanovic made her official, much-improved start on Twitter.

Hey guys, nice to join you! :) pic.twitter.com/QJgd8idFOs — Ana Ivanovic (@AnaIvanovic) August 22, 2013

Most of the tennis world quickly welcomed Ivanovic, but none more awkwardly than Twitter’s most-followed tennis player, Rafael Nadal. The world No. 2, who has nearly 5 million Twitter fans, wrote a 140-character message that sounded like the introduction to one of those e-mails from a Nigerian prince.

@anaivanovic welcome to this mean of communication. Looking forward to exchanging tweets with you. — Rafa Nadal (@RafaelNadal) August 23, 2013

Well, it probably won’t be the last time a man tries to uncomfortably engage with Ivanovic via Twitter.

Ivanovic is seeded No. 13 at next week’s U.S. Open.
