Our right hand bats are Cain who is a great all around player but not a power threat, Braun who is still a decent player but hurt a lot, Aguilar with his .304 slugging pct, Grandal who is better as a lefty, Hiura who will be great but maybe not this year, Arcia who is not a great offensive player and Perez with his sub .300 OBP. We can definitely use an upgrade at first base if Aguilar doesnt show major improvement. If Aguilar improves dramatically in the next month or so maybe we don't have to make a move like this but there is a good chance that he doesn't.
