To the uninitiated, the first 2 days of a tennis tournament is usually for the qualifiers. Since the Malaysian Open is a relatively small tournament, there are only 4 qualifiers allowed.
These are usually players ranked just outside the top 100. Their final round will be tomorrow and I think the ranked players are going to make it - Yuichi Sugita, Luca Vanni, Michal Pryzsiesny and Mischa Zverev.
These are all talented guys. Luca has reached the final of an ATP tour while both Mischa and Michal are former top 70 players. Yuichi is a rising star and if he does well here, he should break into the top 100.
