Juan Yasser Serrano is lanky Cuban righthander who defected to the United States in April 2009. Serrano gained some attention in the US when he helped the junior national team to a 2-1 defeat of the USA for at the Pan-Am Games, but that's the extent of his exposure in America. Back in Cuba, he posted a 16-23 'lifetime' record as a starter, and didn't look like much of a premium prospect in his final year with Villa Clara. We can forgive his mind being on his pending defection, but what we have trouble forgiving is the 6.46 ERA and .312 opponents' batting average across sixteen starts.

Yasser's fastball is a 92mph variety with some natural late movement. His breaking pitch, a slurvy slider, isn't major league quality and his changeup is undeveloped. A raw prospect, he belongs in some organization's rookie league, where instructors can break him down and build him up into a polished pitching machine.
