The 2017 baseball season calendar should be online very soon.

I expect the above link to be updated real soon. The opening day will be on Friday October 13, 2017. In Santo Domingo it will be Aguilas vs Licey Tigres. I am not sure if tickets will go on sale before game day but if you go to the stadium game day early morning you have a very good chance of getting good seats, at least I did last year.
