Tigers manager Brad Ausmus is undecided on who will start opening day, according to MLB.com.

Justin Verlander has been the team's opening day starter in the past, but faces competition from both Max Scherzer and Anibal Sanchez. Ausmus mentioned all three members of his rotation will be considered for the opening day start. "You really have three legitimate Opening Day starter type pitchers on the roster," Ausmus said. 

Verlander is likely the favorite considering his track record, but he's expected to take it easy early in camp. If he can't ramp up his activities as the season nears, Sanchez or Scherzer could sneak in and take the role.
