SCOTTSDALE, Ariz. -- Much can change before the D-backs set their season-opening roster, but as it stands right now, it looks like the team will carry five outfielders, six infielders and two catchers.
As far as the infield goes, Paul Goldschmidt, Aaron Hill, Martin Prado, Eric Chavez and Cliff Pennington are all but locks, with Pennington set to back up either Didi Gregorius or Chris Owings at shortstop.
With outfielder Cody Ross looking like he might be healthy for Opening Day, and Gerardo Parra, Mark Trumbo and A.J. Pollock locks for the roster, it leaves one spot open, with Tony Campana, Alfredo Marte, Matt Tuiasosopo and Shelley Duncan among the candidates.
Given that Ross is coming back from a dislocated and fractured right hip, the D-backs are leaning toward carrying a fifth outfielder rather than another backup infielder.
"Probably more an outfielder than an infielder, just because Cody, I think if he is healthy and ready to go, we're not going to want to overdo it with him right off the bat," Towers said.
Tuiasosopo's versatility could work in his favor, as he can also play third base as well as first.
