Tigers officially place Bruce Rondon on 15-day DL. That puts active roster at 25 ahead of 3pm ET deadline for Opening Day.

Rondon came down with some biceps tendinitis at the end of spring training and also battled some neck discomfort in early March. Neither are serious injuries, but the hard-throwing reliever is on his way back from Tommy John reconstructive elbow surgery and was unable to pitch on back-to-back days this spring. The hope is that he’ll be ready to join the Tigers’ bullpen next week. This disabled list stint is retroactive to March 28.
