Cargo just isn't a good player anymore. His career wRC+ is 118, so its not like he has a long history as an elite hitter. Now after numerous injuries he's probably a liability defensively and on the bases.
Yeah. Gibby has been managing these people for years. He knows them pretty f***ing well. If he thinks Edwin needed a day off, it's absurd for a fan to think he knows better.
That's a perfectly valid reason to give reporters for giving someone a day off for one of the 11ty reasons why a professional athlete might require a day off.
