Marcus looks at the three Pokeballs, already envisioning the fights that would come to pass with the various opponents. Froakie was a quick Pokemon, focused on powerful strikes and ending the battle before the opponent can take part. In that regard, choosing Squirtle, a heavily defensive Pokemon, would be counterproductive. In the same vein, Snover was a Grass Type, likewise making it a poor choice to battle as it would have an advantage against his Water-Typed Froakie. All that left was the Spheal. It was from the Academy which, for some reason, Marcus felt meant the Pokemon was a fortuitous choice.

"I'd like to battle the Spheal, please," Marcus states, praying that he made the right decision.
