DETROIT — The first Tigers player to get the day off after clinching is ... Rick Porcello.

Scheduled to start the series opener against the Marlins, the Tigers switched it to Jose Alvarez Friday morning. The team web site still lists Anibal Sanchez (Saturday) and Justin Verlander (Sunday) as the final two starters of the series.

Alvarez will be making his sixth start for the Tigers, after filling in earlier this season for the injured Sanchez. He's the only extra starter the Tigers have used this season, the lowest number in all of baseball.

Porcello is likely to be the odd man out of the four-man playoff rotation for the Tigers, so don’t be surprised if he gets some relief work in the series, considering he’d otherwise end up with 12 days off between appearances.

The Tigers are likely not done fiddling with the rotation, either, since Sunday’s starter, Verlander, would be the only one on normal rest for the Oct. 4 playoff opener. Max Scherzer, the odds-on favorite to start that game, would be on eight days rest, if he does not throw this weekend.
