May 23: Lyles is working to improve the location of his pitches, the Houston Chronicle reports. According to his catcher, Carlos Corporan, Lyles's location is so good that he "doesn't know how to throw balls." Nine walks in 25 innings indicate there may be a bit of hyperbole with that statement, but the main point is that Lyles is still learning how to throw good waste pitches, while making sure that when he misses, he doesn't miss over the plate. He'll get the Rockies the next time he toes the rubber.
