I have been hearing Perez fans screaming potential for years and it hasn't happened yet. He will never be one of the elite starters of the game. He is 27 but this will be his 8th season with no signs of curing his control problems. Jonathan Sanchez is going down the exact same path as Oliver Perez which is why I don't have much faith in Sanchez. Lowe might regress but most likely not to the 4.39 ERA that Perez has for a career.
