Yep. His best chance to take a big clay title had to be Monte Carlo 1995 against Thomas Muster.
Becker had a 2 set to love lead, but in those days Masters finals were best of 5 sets. It was on his racquet in the 4th set tiebreak. He had two match points at 6-4, double faulted, and Muster went on to take the rest to win the tiebreak 8-6, and Becker was crushed, getting bageled in the deciding 5th set.
Here is the full match...
Respectfully,
masterclass
Muster brought superior fitness and his relentless will to win that day.
Muster did not lose many finals.
He was a clutch performer at the big dance (finals).
