Injuries to Matthew Boyd and Spencer Turnbull have forced the Tigers to call up Matt Manning. He's Detroit's top pitching prospect. However, Manning's time hasn't come yet. He's being rushed to the lineup too far ahead of schedule. Manning still was learning the ropes in Triple-A where he had an 8.07 ERA for Toledo while surrendering 11 homers in 32 1/3 innings. 

This will be Manning's second big league start. He pitched five innings against the Angels this past Thursday giving up two runs on four hits in five innings. Now the Cardinals have a first-hand scouting report on Manning. They know for instance that he threw 70 percent fastball against the Angels. It's hard to rely solely on just one pitch in the big leagues. 

John Gant goes for St. Louis. He has a respectable 3.50 ERA and a 2.08 lifetime ERA against the Tigers in three appearances, including one start. 
The Cardinals own a huge bullpen edge especially at closer with Alex Reyes, who has 17 saves and a 0.82 ERA.
