The choke wasn't THAT big I think, you have to give credit to Stebe as well. He played good return games when Andi served for the set/match.
Stebe played a very good match overall, and I think Beck was getting tired to the end. Stebe could have won the decider 6-4 when he had 4 BPs at 4-4.
Then in the TB Beck already led 4-2, but made one terrible UE earlier in the TB and another one and then Stebe played some great shots to win this thing.
Up to 89 in the rankings now, AO MD place is 100% sure now. Hopefully he won't be too tired for tomorrow's final (revenge) against Sela.
