Former longtime Orioles starter Chris Tillman is making a comeback attempt, reports Britt Ghiroli of The Athletic. Tillman has been working with Dave Wallace, his former pitching coach in Baltimore, at Cressey Sports Performance in Florida since February, Wallace tells Ghiroli.

Tillman, who recently turned 33 years old, was a regular in the Orioles’ rotation for a good chunk of the last decade. He broke into the majors in 2009 and worked as up-and-down starting depth over the next couple seasons. By 2013, Tillman had locked down a permanent rotation spot, making at least 30 starts every year from 2013-16.
