I agree with Ed, don't battle the males, it's un-necessary. And it is WAY early in the season to even begin to stress.
Put him in when the girl is in shed, put another girl's shed in with the female you want him to breed to, put sperm plugs from another male on her back, pair when a weather front comes in - try all those - he'll get it.
I'm going to have to dig out my VPI book where the Barkers state that they never battle their males, because they've had too many defeated males go on to never breed. Not worth the risk.
