Edwin Jackson understands the fragile nature of being a Black player in Major League Baseball.
The former A's pitcher -- who also has suited up for 13 other franchises across the league -- believes being on the roster bubble is different when you are Black.
"Being on the bubble, a bubble player, where it's maybe myself and a white player, and myself not getting a job because I'm Black," Jackson told NBC Sports Bay Area's Monte Poole and Logan Murdock on the July 3 episode of "Race In America: A Candid Conversation."
"I've been in the office before where, I've been told that I needed to go back and work on my slider, I'm like 'My slider? That's what I came up on.' If you told me I need to go work on a changeup, then at least it wouldn't have been a slap in my face.
"You tell me I need to go work on my slider, and that's a better pitch for me than my fastball, it's clear and evident why I'm going back to Triple-A."

Jackson signed a minor-league contract with the A's in 2018, and ended up going 6-3 with a 3.33 ERA over 17 starts for Oakland after being called up on June 25. He was traded to the Toronto Blue Jays in May of 2019.
