I agree that Holt likely makes the opening day 25 man roster, but with a new manager, maybe he doesn't.
I'm not so sure Marrero is so good that we can't afford to DFA him, but then again, is Holt that good that we can't afford to keep infield depth by starting him in AAA and keeping Marrero around?
Same can be said about Swihart. His ability to catch makes him a worthy choice as a 25 man roster player. We can afford to PH for Vaz or Leon in the middle innings, if needed.
If Swihart can play LF, maybe he knocks Brentz off the roster. If he can play 1B, maybe trading HRam becomes an option.
Some interesting choices, but nothing earth-shattering, if we have to let Brentz, Marrero or Swihart go., of if we keep Holt in AAA a little while.
There's also the phantom DL in play.
