Re: Will Billy Hamilton get called up this year?
A couple of things to remember....unless they've changed since I learned them last year.
If he's brought up to the big leagues, but never sent back to AAA, he will not use an option. So in theory, they could call him up Sep 1 (give or take a day depending on injury and what you want to do w/ a potential playoff roster), keep him up the rest of the season (which you would do anyways) then still retain all 3 options.
If Billy needs to be optioned back down the minors each of the next 4 seasons, then we probably won't regret waiving him all the much in season 4. If he's not ready to be a full time player by then, then he's nothing more than a 5th outfielder/pinch runner buy with limited value.
I say yes, call him up on Sep 1 give or take a day each way depending on injuries/playoff roster implications then decide to start him off in the bigs next year, or option him back to AAA for more seasoning.
