I'm pretty sure Laika is referring to Robertson as the OF that's a strong side platoon who might have plus power. There's no chance they believe Horwitz can play a passable LF or he'd have been out there for all of Spring Training. I think Horwitz takes over Vogelbach after his 45 day clause or whatever is about to reach. They're not gonna pay him his full season salary for a plug who can only hit RHP okay providing zero versatility on how to use him. Votto is a complete wildcard, if he looks alive then Horwitz is in tough luck, but more likely than not he's 40 years old and cooked.
