Jack Sock was beaten by the part-time Croatian tennis player Matija Pecotic at the Delray Beach Open. Pecotic had to qualify for the main draw but somehow managed to beat Sock 4-6 6-2 6-2.

The loss must hurt for Sock, who was once ranked in the top 10 in the world.  Pecotic works full-time as the director of Capital Markets for Wexford Real Estate Investors. He was ranked 206 in the world in 2015.

Pecotic joked that he will need to ask for another day at work to play the next round.

I had to leave work early today. I had to send an email to the whole team. My boss let me off. I’m going to have to ask for another day off tomorrow.

Despite working full-time, Matija Pecotic said that he trains five to six times a week before or after work. But his hitting partners are usually from work or friends, not professional tennis players.
