How to play against Singed?

Singed is a funky one, he is tanky and he also is very very fast. Don't forget his poison. Number one rule on league of legends is to not chase a singed. To answer your question on how to beat him is to ask for ganks from your jungler since singed would do something called proxying your lane where he goes behind the tower and kills minions, with your jungler you two should be able to get him.
