EditorGUILayout.ObjectField redundant space between label and object field?

This pretty much says it all:

Look at all that redundant space between the label and the field. It looks so stupid. How to get rid of it? How to make it more compact?

Code:

 public override void OnInspectorGUI()
 {
     var use = target as SingleItemUse;

     GUILayout.Label("Item entry", EditorStyles.boldLabel);
     GUIHelper.HorizontalBlock(() =>
     {
         use.entry.placement = EditorGUILayout.ObjectField("Placement", use.entry.placement, typeof(Transform), false) as Transform;
         use.entry.item = EditorGUILayout.ObjectField("Item", use.entry.item, typeof(Item), false) as Item;
     });
 }

Thanks for any help.
