Martines established himself as a legitimate prospect in 2000. As impressive as his 2.26 ERA at High Desert was in 1999, his 2.81 mark last season may have been more impressive considering El Paso is one of the most hitter-friendly parks in the minors. Martines didn't appear to have much of a future until he followed the same path as Bret Prinz, learning to throw sidearm with the help former minor league pitching coordinator Gil Patterson and sidearm specialist Brad Clontz. Martines took to his new delivery quickly. He throws around 90 mph with nice command and has become more resilient. He'll need to develop a breaking pitch if he's able to take the final step toward reaching the majors. But he has a chance, based on how quickly he sparked a once-nondescript career.
