Félix Pérez is looking for a second chance
Ex Isla player Félix Pérez earned great reviews when he hit the longest ball anyone has seen a player hit a ball at the Yankees complex. Pérez blasted the first pitch he saw sending the ball over the building in right field.
The next day, he led off with a home run at the Cubs complex
