How viable is support Evelynn?

Hi.

I just had a ranked game in which we had Evelynn support and she did really well.

How viable is Evelynn support? Is it considered a sleeper pick?

According to Lolalytics website, she has 49.31% win rate in the support role, but the pick rate is very low (only 6K), so I'm not sure how trustworthy are those statistics.
