Walter Herrmann Heinrich is a professional basketball player from Argentina and plays as a forward. Heinrich was pulled into the professional basketball structure in Argentina in 1996. Signing with Olimpia Venado Tuerto, Heinrich stayed with the team for 4 years during which he won two slam dunk contests held by the Argentine Basketball League.
Shifting clubs in 2000, Heinrich continued to stay on and play in Argentina, although he shifted clubs to Atenas Cordoba. In 2002, Heinrich was named as the MVP for the finals of the Argentine League, a trophy that his team won.
Heinrich moved to Spain, following his triumph in his home land, and joined Baloncesto Fuenlabrada in 2002-03. Continuing from where he left off in Argentina, Heinrich was named as the ACB League MVP of the year before deciding to move to Unicaja Malaga. From 2004 – 2006, Heinrich stayed with the team before deciding to move the USA and try his hand at the biggest Basketball League in the world, the NBA.
In 2006-07, Heinrich began his NBA career with a single year deal with the Charlotte Bobcats while getting an option for the 2nd year. Impressive in his game at the top level, Heinrich ran away with the rookie of the month title for the Eastern Conference, in March 2007. Averaging 9.2 points per game with 2.9 rebounds, Heinrich was named to the NBA All-Rookie Second Team by the end of the season. The Bobcats decided to keep him on for the 2007-08 season as well.
In December 2007, despite his contract extension, Heinrich was traded out to the Detroit Pistons in a move that saw Nazr Mohammed go the other way.
After a productive first year for the Pistons, Heinrich earned a contract extension for another season, keeping him in Detroit.
At the International level, Heinrich represented Argentina at the 2001 Americas Championships as well as at the 2004 Athens Summer Olympic games. In both cases, Heinrich was key to Argentina grabbing the gold medal in each of the competitions. However, at the 2006 FIBA World Championships, the team had no such luck and Heinrich returned empty handed.
