Major League Baseball has dropped its 100-game suspension of Rockies catcher Eliezer Alfonzo for a positive drug test because of the same procedural issues that came up in the Ryan Braun case. Alfonzo is eligible to play immediately, according to a person familiar with the decision. Mostly a backup during six major league seasons, Alfonzo became the first player suspended twice for performance-enhancing drugs when the commissioner's office announced a 100-game penalty last September.
