Just to give a brief example of the type of season Josh Hamilton is having, consider that he is in a mini-slump over the last week (.261 AVG, 0 HR, 3 RBI)—yet he still has a good lead in all three Triple Crown categories.
He'll need to get to back to where he was, or at least close to it, because the Triple Crown will not be easy to accomplish. This is pretty obvious, considering it hasn't been done in 45 years.
There are so many specialists today in baseball: guys who hit for average, drive in a lot of runs or hit a lot of homers.
Here are five players in each category who will threaten Hamilton's Triple Crown bid. There are probably a few players who deserve to be on this last who aren't, but I tried to focus on guys who are regulars in these categories as well as some surprising players having great seasons thus far.
