Since the SF Giants traded for slugger Rafael Devers, he has struggled to get going at the plate. Part of that may be due to the pressure of being on a new team, but it may also have to do with some nagging injuries he is dealing with.
Devers has been dealing with a groin injury, but it was recently revealed that he is also dealing with a disk injury in his lower back. Both of these things have to be affecting his performance at the plate and they have certainly prevented him from playing in the field at first base which was the plan initially.
