Lim is much better than what his ranking suggests. He would be ranked at least top-250 without so many injuries. He's still young though, so hopefully he can keep climbing up the rankings.
Anyway, this easy win against Ito was really unexpected of course, especially considering the fact that Lim was 4-6 0-4 down against Nam H-W. in the first round and saved few mps serving at 4-5 and 5-6 in the 2nd set.
Can you say more about his injuries, has he already had surgery?
