25-man roster announced: Ryan Rowland-Smith, Chris Owings, Tony Campana, Tuffy Gosewisch in

Your everyday shortstop: Chris Owings

Owings appears to have won the battle with Didi Gregorius for the shortstop position, Gregorius being optioned down to Reno. It seems that the gap in offense was just to big to ignore. This spring, Owings hit .288 with an OPS of .793 coming into today; he also showed decent plate discipline, drawing four walks (only Parra and Goldschmidt had more). In comparison, Gregorius hit .222, but with little beyond that (two walks, no home-runs), resulting in an OPS of .522. We'll see whether the team looks to trade Gregorius, or is happy to hold onto him as a backup plan, in case of injury or poor performance.

Your backup catcher: Tuffy Gosewisch

If Henry Blanco wants to play this year, seems it'll be with another team. It seems the Diamondbacks will try and trade him so he can get his wish, but if not, he'll likely be the assistant hitting coach. This had got to be an amazing day for Gosewisch, who made his major-league debut last year, sixteen days short of his 30th birthday, and is now an anointed part of an Opening Day roster. All credit to the man for persevering in the pursuit of his dreams, and it seems likely, barring injury, he'll be living the big league life for all of this season as Miggy's backup. No offense, but hopefully he doesn't see very much action!

Your fourth outfielder: Tony Campana

Speed kills. And with seven stolen bases in seven attempts this spring, Campana looks set to be a finely-honed weapon for late innings off the bench. He hit .261: though none of those were for extra bases, that matters less with him than others, since he can turn a single into a double much of the time anyway. I don't think he'll get that many starts, though may see the odd one against a right-hander. But I imagine he'll definitely get into his share of late games, particularly if his run becomes of great importance.

Your 25th man: Ryan Rowland-Smith

There were several ways the team could have gone for the final roster spot. They could have held on to both Owings and Gregorius. However, in the end, Kirk Gibson went for an extra bullpen arm, and Ryan Rowland-Smith - one of our winners this morning - was the recipient, giving us a veritable plethora of left-handed relief options. This is likely to be temporary, until Cody Ross is ready. On that front, Ross will start the season off on a rehab assignment at Reno, so it could be a week or more before he's back with the team.
