Well from what I saw last September Mullholland has a rubber arm and can pitch every day.

But on a more serious note... Mullholland is one of those special cases... a reliever that can also start. Those guys do not have to be at a BFA of 30 in order to be effective. Although I did think that the rules say there is no penalty as long as their BFA is 10 or more. Which means in the example given he should have had a little more trouble because his BFA was only 5.
