I get all that, but my point is Liriano and Flores are both out of options and Santana has one. It was thought earlier that Flores wouldn't be ready to start the year. Liriano is only a year older than Santana, and has been rated high as #39, while Santana highest rating was #71 last year. It's now or never for Liriano more so than it is for Santana. Sure he could play CF, but that's not his best position either and there's multiple other guys in the hunt there too. If he has a strong spring, he'll have to be on roster or he'll be lost on waivers. Flores, too, if healthy is almost assured of roster spot, given his option status and his much needed LH bat. If they went with Liriano and optioned Santana, and Liriano struggles, then they stand a much better chance of getting him through waivers.
