That's right, z. here's the quote from CBS sports:
"Hammer has yet to start throwing during spring training, but said Monday that he isn't dealing with any sort of injury, Matt Gelb of The Athletic Philadelphia reports.
It appears the Phillies are simply taking it easy on the 23-year-old Hammer after he compiled 71.1 innings in his second professional season -- nearly double his total from 2016 -- before taking part in the Arizona Fall League."
My guess is they'll work him into shape in extended spring and bring him up in May to limit his innings. They might be doing the same thing with Fanti.
