It's crazy ... considering just a few months ago Sabathia was pushing 300 pounds -- but the 6-foot-6 future Hall of Famer (?) has clearly been putting in work during quarantine to get his bod right.
Of course, it's good for Sabathia to be carrying less weight now that his playing days are done ... he dealt with knee and shoulder issues the past few years as well as a scary angioplasty procedure in 2018.
As for how the dude's lost the lbs ... remember, he went vegan a couple years ago -- so seems plants and a lot of hard work!!
