Full guess from the previews. He enjoys his dad, they eventually end up fighting, he finds out why he wants to pitch, gets motivated by April, comes back to the States re-invigorated and season finale ends up with April telling him she doesn't want to be with him anymore.
That is completely and utterly possible. Fairly accurate guess given the natural course of this show.
