Alvin Lockhart 2007

From MLB Power Pros Wiki

Alvin is your rival from the beginning. He is a star player who mistook the Tulips to be an elite team (the Tulip's LADIES' softball team was the good one). He impresses everyone from the start. Unfortunately, most of the time he develops a shoulder injury that goes unnoticed (except by Peter). He leaves the team. The next time you meet him will be in the Championship game of Year 3, during which he will be a member of the opposition. Sometimes, if he becomes the Tulip's team captain, he will stay, making the game a lot easier because he such a phenomenal pitcher and can hit fairly well.

Alvin previously played with Patrick of The World Gatherings, possibly in high school; Patrick was an expert at catching Alvin's special mirage knuckler-pitch, but after getting beaten when Patrick missed a start, Alvin struck out on his own to prove that he could succeed without Patrick calling the game.

If Alvin leaves your team, you will see him playing for the Champion Rings later on.
