DETROIT — Robbie Ray will make his big-league debut on Tuesday.

That’s been known for nearly a week.

What was not obvious was how the Tigers were going to get him on the roster.

Now that’s known, too.

Detroit outrighted the contract of Jordan Lennerton to Triple-A Toledo to clear a spot on the 40-man roster early Monday afternoon, then opened a spot on the active roster by optioning reliever Jose Ortega to Toledo after Monday’s game.

The 25-year-old Ortega has a wicked-looking ERA of 27.00 after giving up four earned runs in 1 1/3 innings in his only appearance of the season on April 26, after being called up as reinforcement for a taxed bullpen that day.
