This seems like a weird argument. As I recall, the Rangers acquired three pitchers at the deadline. One is injured and not on the roster. One hasn’t appeared in a game this series. One started yesterday, lasted four innings and gave up five runs, granted, one wasn’t earned. I’m going to bet, that’s not what the Rangers were going for.
While Eovaldi looked great against Tampa, let’s not forget Seattle tagged him for five runs in five innings and 7 runs in 3 1/3 innings in late September. So, he can be vulnerable.
