For the record, this is why I wasn't onboard as Cesar for a guy to immediately pick up his option. To say the least, there are a lot of 2bs possible, and it is unlikely you'll be left without a seat. He is a fine option though, but with so many infielders on the market there's a possibility to upgrade or get similar production for similar price - but why lock it in.
But it's not life or death and if they pick it up, it's fine. Even if they make a mistake there will be 2bs available next deadline and offseason etc, etc.
