Lu was choking like a maniac at the end. Lu served for the match in the third set at 5-4, hit a DF on his own MP, and then a DF on BP. Then in the tiebreak, when he lead 5-4 with the next two points on his serve, he immediately gave back the minibreak. Thankfully, on his six MP, he finally ended it with a FH winner.
Regardless of the choking, it was still a good win for Lu. He'll face Johnson in the second round.
He chok but at the same time was very clutch with 2 3 balls at the line.
