The top of the sixth today against Tennessee is why Clark pulled Luna. With two out, she walked a batter, hit a batter, and walked a batter to force in a run that was there due to a leadoff walk. Luna does that. She gets into some sort of funk and just makes mistakes. We've seen Ricketts do that in the past. There was no reason to give Tennessee a run, especially since Texas is not hitting either Renfro. As the announcers have said, Texas just lets some very hittable pitches down the middle go, like they are surprised.
