Opening Day of the 2015 Major League Baseball season is inching closer. In turn, teams are inching closer to “completing” their 25-man rosters.

Yes, the quotation marks on “completing” are necessary. Because while a complete roster technically means a roster without holes, every team is going to break camp with at least one notable hole on its roster.

But some holes will be more notable than most, and those are the ones we’re here to talk about.

Ahead is a list of 10 key roster holes that look destined to go unfixed by Opening Day. In arranging these, my focus was on positions that teams needed to figure out coming into camp and have so far failed to do so. Barring a last-minute trade or surge from an in-house option, things figure to stay that way.

We’ll go in order of how concerning each problem is. Step into the box whenever you’re ready.
