It is never fun to talk about an injured guy's career in the past tense, but there is no real way to think about Adalberto Mondesi other than in that way. The Red Sox took a cheap flyer on him in the hopes that he would be able to recover from tearing his ACL and become a terror on the basepaths for them.
Unfortunately, that was not to be as his recovery was very, very slow and he experienced setbacks that basically shut down his rehab. At this point, it is fair to wonder if Mondesi will ever play baseball again given that the last word was that he still wasn't cleared to participate in baseball activities after two seasons on the shelf and about to hit the free agent market. Wherever he ends up, hopefully he can get healthy again as it would be a shame to see a guy that talented have his career completely torpedoed by an injury.
