(Reuters) - Twenty-two time Grand Slam champion Rafa Nadal fell 7-5 6-4 to Czech Jiri Lehecka in the fourth round of the Madrid Open on Tuesday, marking his final appearance at a tournament he has won five times.

In just over two hours, a feisty Lehecka thwarted Nadal's hopes of reaching his 100th Masters 1000 quarter-final after a fairytale run in only his second tournament since January as the Spaniard struggled with injury.
