Jörn Renzenbrink (born 17 July 1972) is a retired professional tennis player from Germany.
Career
A right hander, Renzenbrink had his best Grand Slam performance in the 1994 US Open, when he made it into the fourth round. He started his campaign with a straight sets victory over South African Grant Stafford, followed by a four-sets defeat of Morocco's Karim Alami and then a win over Italian Andrea Gaudenzi. In the fourth round he met Jonas Björkman and took him to five sets, but lost.
Renzenbrink never won a singles tournament on the ATP Tour but was runner-up on one occasion, at the 1994 KAL Cup Korea Open. He did however win a doubles title, with fellow German Markus Zoecke, as qualifiers, at the 1995 Hall of Fame Tennis Championships in Newport, Rhode Island.[1]
He won two ATP Challenger Series tournaments during his career, the first in Andorra in 1993 and the other at Aachen in his home country.[2]
