Yachiru is really a complimentary character to Kenpachi. That is why we know very little about her abilities in combat. However like Godisme said her spiritual pressure is quite high. Only three characters have ever made the "face" when exerting their spiritual pressure. The first two, Ichigo and Kenpachi, have two of the highest spiritual pressures in all of Bleach. While there is no more evidence to support it, I wouldn't be surprised if Yachiru's spiritual pressure is on the same level as a captain.
