While the Arizona Diamondbacks have been busy signing free-agent pitchers, they just let one go who was once a huge prospect.
In the first round of the Triple-A phase, the Athletics ended up selecting Abel Mercedes from the Houston Astros. In the second round of the Triple-A phase, the A's added a similar pitcher in Darlin Pinales, a 23-year-old right-hander that had been in the Arizona Diamondbacks system.
