The Rangers stadium is awful when it is hot. Because of the office building along the LF wall, there is no opening in the OF for air to flow through. The park is oppressively stagnant when it is hot there, which is pretty much from May to October.
Last I checked, Thompson has been about 50 OPS points WORSE than Engel, which is just scary. I don't think that he is THAT bad, but he sure hasn't shown otherwise at the major league level for quite some time now.
