With Spring Training fast approaching, MLB.com takes a look at a different aspect of this year's D-backs squad each day this week. Today's topic: Predicting the 25-man roster.
PHOENIX -- Predicting an Opening Day roster halfway through Spring Training is challenging enough. Trying to come up with one before pitchers and catchers even report? Nearly impossible.
With that being said, here's an early look at what the D-backs' 25-man roster could look like on Opening Day. We'll continue to do these periodically throughout Spring Training and see how they change.
Catchers:Jeff Mathis, Chris Herrmann, Chris Iannetta
The D-backs will likely carry three catchers because of Herrmann's versatility -- he can play left and right field, as well as in the infield.
Backup outfielder:Gregor Blanco
Assuming the D-backs carry 12 pitchers, three catchers and three backup infielders, that leaves room for just one backup outfielder, but Owings can play all three outfield spots and Herrmann can play the corners. Blanco might be the early front-runner, but also keep an eye on Socrates Brito and Jeremy Hazelbaker.
Bullpen:Fernando Rodney, Randall Delgado, Jake Barrett, Evan Marshall, Andrew Chafin and Enrique Burgos.
Honestly, this is way too early to even begin to sort out the bullpen. There will be a fierce battle for spots, with Rodney, Delgado and Barrett as the only ones very likely to make it at this point. The D-backs also have some veteran non-roster relievers who could sneak into a spot. There's also a chance one of the starters that doesn't make the rotation will slide to the bullpen, too.
