The asymmetric wake is a byproduct of the location of the separation points on the third and 1st base sides and not the direct cause of the force. The force on the ball is due to the pressure distribution on the ball. Also turbulent flow is indeed faster than the laminar flow (when all other parameters are the same) but you are getting cause and effect wrong..it isn't faster because it is turbulent but turbulent because it is faster...There is still a lot of conjecture about the exact cause of the force that makes the ball break. There are more posts in the thread that I linked to that update the author's thinking. Turbulent air moves faster laminar flow air so is it Magnus Effect? The author thinks it is due to the differences in the wake on each side of ball that. The wake is affected by the seams.
