He has been Auckland-based since July last year coaching at the Cockle Bay club. When Reynolds travels to Germany he will be based in Brenen.
"It's a good time of the year to go as our summer will be finishing. While the team I will play for will be second or third tier it will be a good opportunity to make some money. There's a lot of ATP ranked players in the competition and our No 1 player is ranked 200 on the ATP world rankings.
"I will aim to work my way into the top-tier interclub comp and after interclub play I intend to tackle some Futures tournaments on the men's professional circuit," Reynolds explained.
It will be his second overseas stint. In 2016 he had a three-month stint with the Ragin' Cajuns men's team at the University of Louisiana at Lafayette.
Recent results suggest Reynolds is more than ready for his next overseas trip. He reached the quarterfinals of the singles at the New Zealand championships where he and brother Finn, who is now on a tennis scholarship in the United States, were beaten finalists.
"That doubles placing has to be the highlight of my career to date," Reynolds said.
He finished sixth at the Te Anau Open which was an invitation-only event for the country's top eight players. Reynolds also reached the last qualifying round of an ATP tournament in Australia, helped his Cockle Bay team record a top-five finish in Auckland's Caro Bowl interclub competition and he won the under-23 title at the Hawke's Bay Junior Open.
