I don't think he's in line for helping the big club, but as it stands right now, we only have one what I would call legitimate 1B prospect in the entire system (McCabe at Rome). If Olson were to go down, we'd have nothing.
If Olson were to go down, TDA or Murphy need to get a 1b mitt until we make a trade. Honestly I'm surprised they haven't entertained the idea of Ozuna taking some reps at 1B for emergency use.
That, or send Riley to 1b and call up Grissom to play 3b. I prefer option A though, because Grissom's bat just ain't there yet.
