I believe the IL stint idea was killed in the last CBA negotiations when they also limited the number of times that a pitcher could be sent up and sent down to AAA. This is the exact situation that the PA would file a grievance if suddenly Alcala lands on the IL without showing some reasonable inference that Alcala is actually injured. Alcala will have a right to be released and choose free agency if he is DFA'd. I also believe he will be picked up by another team. That team may be the Rockies, Angels, White Sox, or Marlins, but another team.
As with SWR, I believe we are stuck with him for at least another start or two as likely need to see what he can actually deliver, if anything. Festa had a recent worse start than SWR, albeit in a worse situation, but we are not screaming that Festa has to be replaced right now. Another reason I say we are likely stuck with SWR is that we still don't know what kind of a team we have right now. We don't know what SP we may be available to trade for, if any that we can afford with prospects or salary. Finally, we need to look at pitchers in AAA on the 40-man. Adams, who was just sent down, I believe cannot come back for 15 days unless someone goes on the IL. Raya is pitching today trying to lower his 10.46 ERA in St. Paul, so I don't see him as a ready option. Funderburk is the last man on the 40-man, and we have already seen what he can do. I just don't see any logical options right now in replacing SWR.
