I understand that September numbers are taken with a grain of salt, but wouldn't it make sense to see him in the big leagues now, to get an idea before heading into the offseason whether they really want to look at getting another lefty in the bullpen? Spring training seems awfully late when most of the free agents are snatched up or if he looks good and they didn't need to sign someone else.
Could be the Giants are okay with him resting the rest of the season. No point in calling him up and having him stew on the bench.
I feel like even if they brought in Snelten, and he did well, they'd still be looking at add a veteran lefty in the offseason. And the Giants have a good idea of what Snelten is already. A few innings in September won't change that.
