Marte is scheduled to throw 45-50 pitches for the Mud Hens on Monday. If he gets through that fine, then the Tigers have a decision to make.
"If everything goes right, he would still probably not be available up here until Friday," Leyland said. "So I don't know how that's going to play out. But that's the course for him right now. His next step is Toledo, and that's a big step."
It's an aggressive track, but it's clearly one with the goal of getting Marte back to a struggling bullpen.
Marte was slated to make the Tigers' Opening Day roster before he strained his left hamstring in the final game of Spring Training. It was a bad enough strain that it basically sidelined him for a month before he could pick up his throwing program in earnest.
The 25-year-old has been lights out in his rehab outings. On Monday, he tossed two scoreless innings for Class A Lakeland, allowing one hit while striking out three batters.
