I have just finished looking in an on-line file that may, or may not, contain the baptism record for Granados. The file is an LDS file of baptism record images. So, you have to browse through every record to find what you want as there is no index for it.
To get there, go to https://familysearch.org
. When the main screen comes up scroll down to the bottom. There you will see a list of continents. Select the one including America and Mexico. At the next screen, a long list of LDS collections, select Mexico Catholic Church Records. At the next screen select Sinaloa. At the next screen select Mazatlan.
Now you will see a long list of files available for browsing. As it turns out, the one you are looking for is badly mislabeled. It is called Information Matrimonial 1885 - 1920. To contains baptism and burial records and even a few marriage records. It is chopped up jumping from one type to another and back and forth date-wise. It contains baptisms from Jan 1860 - Sept 1861. It has 188 images. Each image is of facing pages from a ledger book, so each contains multiple records.
When you select that file from the list you will get image 1, that shows the original LDS microfilm number for the data in the file. You can enter an image number in the image number box to jump around the file, or you can move forward and back using the arrows in the upper right corner of the screen.
I hope this helps you find Granados.
