I just saw Rafael Nadal defeat Donald Young in the 2nd round of Wimbledon, 6-4, 6-2, 7-5, and Young was *right there* in the 3rd set, breaking Nadal to get to 5-5, before the pressure got to him, and he hesitated on some really important shots. You can see this because there's a slight loss of intensity, and as so often happens, a player "pulls up" on their shots, instead of driving through them. When they're down, and their backs are up against the wall, players play like there's nothing to lose, and usually hit out with much more fluency.
Still, Young taking Nadal to 5-5 at Wimbledon is an accomplishment - like so many players of today, Young has a tremendous serve and forehand, but his backhand is just too much of a weakness ever to crack the top 10 (not that this is any sort of failing).
Donald Young and Mexican Santiago González got to the finals of this year's French Open Men's Doubles championships, falling to fellow American Ryan Harrison and New Zealander Michael Venus in a tight match, 6-7 (5-7), 7-6 (7-4), 3-6.
