Jose Soriano opens another big series for the Blue Jays, this time against the Tigers.

He'll face Troy Melton Monday, the start of yet another crucial series in a wild-card race that keeps producing must-win matchups.

Toronto hasn't announced a starter for Tuesday's game against Drew Anderson.

Max Scherzer closes out the series Wednesday, with Detroit's opponent still to be named.

Two unconfirmed matchups in a three-game series continues a pattern that's defined Toronto's rotation for weeks now.

Soriano has settled in as a genuine top-of-rotation force since arriving from the Angels at the deadline, giving Toronto real stability at the top of this series.

Scherzer, meanwhile, has been one of the more surprising performers in this rotation, turning back the clock since returning from his own injury issues earlier this season.

Why Tuesday's opening remains the key question

Toronto is dealing with a rotation stretched thin by injuries to Trey Yesavage, Shane Bieber, and Jameson Taillon, all currently on the IL.

That shortage is exactly why Tuesday's starter remains unnamed, likely depending on how the bullpen holds up across the first two games or whether a returning arm becomes available in time.

Spencer Arrighetti has recently found his footing in a bulk-relief role, giving Toronto at least one more reliable option to lean on if Tuesday turns into another improvised pitching day.

The Blue Jays sit right in the thick of the wild-card race, and every series at this point carries the label of "big" for good reason.

Whoever fills that Tuesday gap, whether a traditional starter or another bullpen-day arrangement, will need to hold the line against a Tigers lineup capable of making things difficult.

For a Blue Jays team with 13 games left and one game separating them from a playoff spot, every rotation decision this week carries real weight.
