The moves bring the Tigers' camp roster to 26 players, including the injured Justin Verlander and Bruce Rondon. Both will be placed on the 15-day disabled list, which leaves 24 active players still in camp. Who fills the last spot depends on Verlander's work in the coming days.
Verlander is tentatively on track to start next Sunday at Cleveland, but that depends on how he progresses with his right triceps strain. He's scheduled to stay in Florida and throw off a mound Saturday or Sunday, then face hitters on Tuesday.
If Verlander falls off that timetable, or feels lingering soreness, the Tigers will need a starting pitcher to take his place. That would most likely be left-hander Kyle Lobstein, who has been identified as the "sixth starter" and would have a favorable matchup against an Indians lineup loaded with left-handed hitters.
If Verlander progresses as hoped, the Tigers are expected to still place him on the DL and use the spot on an extra reliever for a few days. Since the DL move can be backdated to March 28, the day after Verlander left his start against the Blue Jays, he'd still be eligible to come off the DL on April 12.
Whichever way they decide, they have to do it when they place Verlander on the DL. By rule, a player sent down out of camp must have 10 days in the Minors from the start of the season before he can be called up, unless he's replacing a player who's going on the DL. By that rule, the Tigers could even recall Hardy or Ryan to fill Verlander's spot if they want.
The Tigers aren't expected to make their decision until Sunday at the earliest. Tigers president/general manager Dave Dombrowski said they could technically wait as late as Tuesday to make a move and still backdate it so Verlander is eligible to return for his tentatively scheduled start.
