Sprinklers in front-yard with tree in the middle - looking for advice

[misuszatek]

Is it a problem to set 90° rotor sprinklers in corners of area with tree in the middle?
The area is 20ft x 20ft, sprinkler range is about 15-25ft while distance from the corner to trunk is 10ft.
Slightly clay soil, tree in the center is River Birch.

I understand that watering trunk might increase possibility of fungus infection but river birch usually likes moist soil. 
Should I be worried or its perfectly fine?

Thank you for any advice
