Hey everyone, I have a question about RL prices!?

Why in some cases are the RL prices (I mean the actual price not the -1.5 or +1.5) same from one another even though the ML prices for the two teams are different????

I'll give an example (I use 5dimes, so these prices are from 5dimes) Comparing the Yankees line to the White Sox line:

The Yankees' ML is -175 while the White Sox ML is -138

But the Yankees' RL -1.5 price is +110 while the White Sox RL -1.5 price is +110 (the same).

Anyone have a clue why, one would thing that the Yankees' RL price would be a lot more than the White Sox RL price since their ML is much more? Anyone can explain this?
