The main cause for concern for the LA Angels’ Justin Upton is that he needs to stay healthy and have a positive mindset for the start of the season. Last season, Upton missed most spring training with tendinitis in his right knee and a sprained toe. He then missed finishing the regular season with patellar tendinitis, which really limited his offensive output; he only was able to finish batting to a .215 average, 12 home runs, and .724 OPS in only 219 at-bats.
In the past Upton has been able to put up many outstanding performances and I’m sure he is going to want to get back to that if he wants to live up the extension he signed with the Angels.
