Here's the strike zone of tonight's home plate umpire, Gerry Davis.

These were provided by Jeff Zimmerman in his game one preview at FanGraphs. If you're unsure of what you're looking at, the box is the standardized strike zone and the colors denote how often a ball is called a strike. The more red, the more often it's called a strike, the more purple the more often it's called a ball (click for a larger image). As you can see, it's a very small strike zone, and he provides two other strike zones to compare it to at the site.
↵You pretty much have to throw it right down the middle to get a strike called more than about a fourth of the time, and the corners you can just forget about. He does seem to call low strikes, which is sadly rare, but he doesn't seem to like high strikes at all. He also has no interest in giving the inside pitch. Also, like most umpires, he'll call pitches well outside against lefties a strike around half the time. that's something Wilson should probably take advantage of against the lefties he'll be facing, and something that might help the Rangers, who may only be starting one lefty.
↵This might end up being frustrating. It might also be a long night, as both pitchers are prone to walk a few (especially the Texas one).
