MOSFET pin numbering - Electronic Circuits Projects Diagrams Free

I have a schematic (see attached) that shows connections to a ZXMN3A01F MOSFET as "pin 1, 2, 3". The datasheet only shows pins as "D,G, and S". How can I determine the correlation between pins 1,2,3 and D,G,S? It seems to me that it would be easy to figure out based on where the leads are coming in from other parts of the schematic, but I'm too inexperienced to do it myself. Googling didn't turn up any results so I'm not sure where to go from here. If I had to guess I would say that Pin 1=Gate, 2=Source, and 3=Drain. Can anyone give me a clue? Thanks, Chris

Here is the datasheet:

You can tell by the type of mosfet and how it's connected in the schematic.

1= gate
2= source
3= drain

That was fast! Thanks for the help!
