So I tried to ask this question in the other Holliday thread but no takers so I'll try a more direct approach.
Assumption: Holliday is clearly ready after ST for major league baseball. Its irrelevant what being ready means. Everybody can have their own metrics. Just assume that he's ready per your metrics.
Through the month of April the O's will play 29 games and its not too difficult set of opponents. So here's the question. How many more games would you need to project the O's to win with him in the lineup to warrant keeping him on the OD roster.
1. Irrelevant to me. If he's ready then he's on the OD roster.
2. 1 or 2 wins better or I would send him down.
3. If its not at least 3 wins better then I am sending him down.
3. Irrelevant to me. I am starting him in AAA no matter what. The extra year of service time is too valuable.
I am flip flopping between 2 and 3. April wins count just as much as September wins.
