Lu would have won this in straights if his level didn't drop. Ryan is at this point in his career far too content to just grind matches out. He plays far too passively, just loops the ball and then runs everything down. He tried to play a bit more aggressively at the start of the second set, but the problem with that is his backhand is at this point too inconsistent for that. Luckily for him, though, Lu's level dropped considerably at the end of the second and Ryan snuck out the set. The third was more of the same, just back to retrieving behind the baseline until Lu coughed up some errors.
With all this being said, most of you are shortchanging him on some things. His second serve, which is already one of the best in the world, was invaluable today.
And at the end of the day, he won, is pushing up the rankings, and will have years to really develop his game to where it needs to get for him to realize his goals.
Did we watch the same match? Sure Lu dropped off a little, but it was because Ryan started giving him no rhythm and varying his shots a lot more.
It seems like he plays up/down to his level of competition, which isn't necessarily a good thing, he's got to keep a level of solid consistent tennis regardless of the opponent.
