The Detroit Tigers have promoted top prospects Spencer Torkelson and Riley Greene to Triple-A Toledo.

They're expected to make their Mud Hens debuts Tuesday night.

The expectation had been that Torkelson and Greene would play out the season at Double-A Erie, waiting until next year to be tested against the veteran pitching in Triple-A. However, recent success pushed their development.

"Any time a big-time prospect has a good week or a good game or a good stretch, there’s always this curiosity whether or not they need to be challenged for the next level," A.J. Hinch said.
