User blog comment:Black Leg Sanji/Fight Prediction 2: Zoro vs Marco the Pheonix/@comment-3986064-20110529145659

Post time-skip they weren't able to defeat an admiral, but now They can do it and I think Zoro and Sanji learned how to use haki as well to do it. The strongest of the crew of the pirate king can surely beat admirals and if they could beat admirals they can beat the commanders of the WB crew as well.
