The Detroit Tigers appeared to have all of their major roster spots sewn up not so long ago. But things can change in a hurry.

The injury bug has bitten this franchise again, which will force some significant shake-ups in the weeks to come.

A knee injury to designated hitter Victor Martinez has put a giant monkey in Detroit’s wrench. Martinez’s recovery from meniscus surgery—due to take place next week—will almost certainly rule him out beyond Opening Day, and potentially as late as midseason.  

With Miguel Cabrera also rehabilitating this winter, Detroit’s two biggest offensive threats could both be watching from the sidelines when April rolls around.

Even if Cabrera is able to DH, it still leaves a big hole at first base. That leaves the Tigers with plenty to mull over.

Apart from this new dilemma, things seem pretty stable. The other position players look concrete in their starting roles, and the rotation is a done deal—notwithstanding a daring move for starter James Shields.

Any other battles waged will be for places on the bench or in the bullpen. The latter could be particularly intriguing with one or two sleepers getting a chance if they have a spectacular spring.

With a few openings available, let’s take a look at the contenders and what their chances are of grabbing one of the available spots.
