Hi Zvonka,
Grammatically, there isn�t anything wrong with the sentence, but it isn�t very elegant. Part of the reason is that she showed:
1. that she was an excellent team player
2. anticipation
3 hard work
As you can see, those are quite different kinds of things and therefore are perhaps better separated.
Also, �she showed hard work� sounds odd. Perhaps �she showed evidence of hard work�?
�Liabilities � is an odd word to use in this context. I think �weaknesses� might be better? I�d also change �projects� because it sounds too specific, but it depends on the original meaning. �Anticipation� is a skill that I�d associate with sport ( �anticipating the ball�), rather than management. So if this is about management skills, I might change �anticipation� to �initiative�.
If I rewrote it, it would look like this:
Mary proved not only that she is an excellent team player, but she also showed great initiative and evidence of hard work despite her weaknesses in other areas.
