Rockies reserve catcher Eliezer Alfonzo has become the first player suspended twice for performance-enhancing drugs under the Major League Baseball testing program. The commissioner's office announced a 100-game penalty on Wednesday. Alfonzo, 32, was suspended for 50 games in April 2008 while a member of the Giants. "I am surprised by this positive test," he said in a statement. "I learned my lesson in 2008 and have not taken any prohibited substances since then. With the union's help, I intend to fight this suspension and look forward to appearing before the arbitrator in the near future."
