Second-division outfit Kaiserslautern started the encounter brightly with Leverkusen goalkeeper Lukas Hradecky tested in the early stages as Danny Hanslick fired home a dangerous effort.
Leverkusen were unimpressed and Jeremy Frimping, Patrik Schick and Florian Wurtz kept Kaiserslautern's defense busy as the match progressed and they took the lead, reports Xinhua news agency.
The undefeated Bundesliga champions showed no mercy and opened the scoring with 1 minute remaining in the final when Xhaka whipped a loose ball from 19 meters into the top left corner, leaving Kaiserslautern custodian Julian Krahl helpless.
Leverkusen took the momentum and should have doubled their advantage, but Schick couldn't make the most of Alejandro Grimaldo's good build-up work.
Kaiserslautern came alive in the closing stages of the first half when Leverkusen's Odilon Koussounou received marching orders for his second bookable offence.The second division side took almost full advantage of their numerical advantage, but despite all this, Tobias Rascal wasted a promising opportunity to restore parity.
After the restart, the outnumbered Leverkusen again assumed control but continued to be wasteful in front of goal as neither Djokhar Amin Adli nor Josip Stanisci could beat Krahl.
Kaiserslautern tried their luck with long-range efforts, but Hradecky was equal to Ragnar Ache's shots in quick succession on the hour mark.
Leverkusen's defense held strong, but Xabi Alonso's men failed to extend the lead as Wirtz and Frimpong went wide in the closing stages.
"We had to face a lot today," said Alonso.The red card made the second half very difficult for us. Although everyone struggled. It's an unforgiving end to the season after not winning against Atalanta Bergamo in Dublin."
