As MLB cracks down on spin rates, Orioles bring Mickey Jannis and his knuckleball into the fray

The same day veteran pitchers Max Scherzer and Sergio Romo nearly removed their pants on the field as umpires searched them for spin rate-increasing sticky substances, the Orioles made the most anti-spin roster move they could: promoting knuckleballer Mickey Jannis to the majors.

Jannis didn’t make it into Tuesday night’s 3-1 loss to the Houston Astros, but the 33-year-old has waited a long time for what will be his major league debut. It’ll be followed by a foreign substance check from umpires; he laughed Wednesday when asked whether they should even bother.

“I don’t believe so, but that’s gonna be part of the game so whatever they got to do,” Jannis said.
