Ahead of Alexander Zverev and Felix Auger-Aliassime's first round matches in Cologne, Germany, the two met up with professional hockey player Leon Draisaitl and showed him a thing or two on the tennis court. Zverev and Auger-Aliassime also tried their hand at playing hockey.
The two seeded stars kicked off their day with a few light rallies with the Edmonton Oilers hockey forward. Draisaitl was all smiles, but decided in the end that it's best he stick to the ice rink.
