They're on a 5 game losing streak with a below average (and unpredictable) pitcher on the mound. They're facing a hot Twins team and they're going against a guy making his first big league appearance which means anything is possible with the guy being an unknown at this level and his increased motivation.
Considering all that, who's laying -200+ on the Rangers?
BTW, my initial lean would be Rangers team total over but it looks like that's gonna around 6. It's a lot to ask a guy who's never pitched in the big leagues to up against the Rangers' line up in Texas (especially when you'd expect them to bring their A game to win here).
