I fondly remember Matt Chico chucking a fastball 90 degrees off target over the dugout and into the stands. That was so bad it wasn't even a wild pitch since it didn't get anywhere close to the plate.
I remember the stories that the Nats had changed Chico's style, freeing him to be again the pitcher he had been in high school / college / minors. "This time, he's fixed".
For all that, I am looking forward to watching Gray and Gore, plus minor league pitchers like Cole Henry, Jackson Rutledge, and Jake Bennett. Maybe Seth Shuman, also.
