I have built a photoshop/excel pairing that utilizes the data available to me to populate assets that I've created into a photoshop template. This allows me to make as many graphics as I want on a template in seconds. Whether its 1 game or the full 15 possible in the MLB on a given day, the graphics are built in the same amount of time.

Below is an example of an entire days slate of games, 15 in total, populated and exported using my excel document in under 1 minute.
