A player like Abreu who has had a track record of success in the majors will likely make adjustments and turn it around.
I think scouts have found a vulnerability in his swing or approach including perhaps his tendency to be late on outside high fastballs with 2 strikes on him.
Whatever the case, I think he will adjust. Maybe he is pressing now and swinging to hard to hit a home run. All he has to do is connect. His arms are like tree trunks. Meanwhile, he is gold glove quality D at first. The other problem now is that neither Mercedes nor Vaughn have been providing him with much protection. We need ALL of them to rake.
