Clase is on leave until the end of August for possible gambling. Looks like Ortiz might have pointed the finger at him.

apparently they are friends in the locker room and out. And share some risky behaviors.

We don't need to speculate on trade value for Clase any more.

According to Hoynes:

Luis Ortiz was placed on leave on July 3. His investigation was supposed to end on July 17 but was extended to Aug. 31 to match Clase’s. “It’s believed MLB’s investigation into Ortiz uncovered information about Clase that led to him being removed from the active roster.

On the theory that the Guardians have to trade someone the rumor mongers are now suggesting:
Santana is too old and too much past his prime to be tradeable
So, Bieber could be moved like Cobb was to Cleveland last summer [netting the Giants an impressive 18 year old pitcher from Cleveland]
And since Sewald is on the IL. and Thomas is on the IL, there's no one anyone might conceivably want
ERGO: Cleveland must be offering Kwan.
They'd better not be. He's one of only a handful of long-term pieces for a remotely potential contender.
