Help with website code?

I've been looking for help with codes for my site for a very long time and I came across this site and thought there are some really intelligent people here so maybe someone here can help me out.

Basically, I'm kind of new in this field but I have a wordpress website for sports and I have a page with a list of baseball players names and at the end of every night I need to update this list with their statistics from the game they played that day/night.

For example (before they play their games)...
Player 1: Russell Martin
Player 2: Mark Texeira
Player 3: Derek Jeter
...and so on for like 50 other names.

At the end of every night, I have to go search for those players and find out what their statistics were for the night and then update the list by typing in all of those statistics.

For example (after they played their games)...
Player 1: Russell Martin - 2 singles, 1 home run
Player 2: Mark Texeira - 1 double
Player 3: Derek Jeter - 2 home runs
...and so on for like 50 other names.

Where or how can I find or create a script or plugin or something that will collect this specific data (stats) from another site and and display it on mine?

Maybe this resource would be useful but I don't know because I don't understand it when I try to read it:
Google - Yahoo fantasy sports API

Any help, feedback, anything will be greatly appreciated.

Regards,
Tony
