Tommy controlled the position, but its hard for me to say that he dominated that round because even though he was in the position he wanted, he was also the only person that was in any trouble in round one. Ben did all the actual damage that round.
Controlled the first round? Sure. Dominated? Maybe in the letter of the law, but definetely not in the spirit of the law.
I give the round to Ben because he had Tommy in some serious trouble not once, but twice in the first round.
