Yankees planning to call up starter Cam Schlittler for MLB debut

The Yankees intend to promote Cam Schlittler to make his major league starting debut either Tuesday or Wednesday at home against the Mariners, The Post has learned.

The Yankees have not made a decision public or etched definitively. But it was their current plan to go with the 24-year-old Schlittler, who between Double- and Triple-A this season had produced a 3.52 ERA in 15 games (14 starts).

The Yanks are in at least a bit of a rotation crisis.

Max Fried, Carlos Rodon and Will Warren have made all their starts this season, but the other two spots have been in flux and became more of an issue with Aaron Boone announcing before Saturday’s Subway Series game that Clarke Schmidt will likely need Tommy John surgery, a procedure that not only will knock him out this season, but potentially all of next season as well.

Marcus Stroman is back for a rotation that was never going to have Gerrit Cole this year after this spring’s Tommy John surgery. Allan Winans will not have been down the requisite 15 days to come back and make a spot start on Tuesday or Wednesday unless an injury strikes and he can be promoted for that reason.

The Yankees believe that Luis Gil (lat), who has yet to pitch this year but is on an injury rehab now, will be a factor to return to the rotation somewhere between the beginning of the second half and the July 31 trade deadline.

Ryan Yarbrough (oblique) is considered more of an August possibility. Acquiring a starter before the deadline has now become more pertinent.

 For now, though, Schlittler appears as if he will get a shot.

The 6-foot-6 righty, a seventh-round pick in 2022, impressed Yankee officials with his work and stuff in spring training. That continued into the season as he excelled at Double-A and was promoted to Triple-A in early June.

He pitched very well in his first four starts before his worst outing of the year last Wednesday — seven runs (six earned) in 2 1/2 innings against the Phillies’ affiliate.
