Since I started this, I'll clarify: last year, Mayer hit poorly upon his callup to AA and then was shut down with a shoulder injury (which, we presume, explained the bad hitting). As a result, I'd think the organization would want him to sustain some success at AA before calling him up, and I'd be surprised if they skipped him past AAA. That said, the hot start is encouraging, and if he can keep this up (well, maybe not this, but if he keeps hitting well), then maybe a Fenway appearance later this summer is on the table. But "if" and "maybe" are the key words there.
