Keynan Middleton doesn't deserve to make the White Sox right now.
Middleton, 29, is in camp as a non-roster invitee. The once-dominant Angels reliever has had some inconsistencies over the past few seasons, bouncing around the league and failing to find a long-term home in any one spot.
Last year, he made 18 appearances for the Arizona Diamondbacks, going 1-2 with a 5.29 ERA, 5.88 FIP, and 78 ERA+. While he did well at limiting walks, the numbers were down across the board for him.
Most of the White Sox's pitching staff has looked sharp in Spring Training (with a few exceptions, like Dylan Cease), but Middleton has not.
In eight appearances and nine innings pitched, he has a 6.00 ERA thanks to six earned runs on 10 hits allowed. He has not done enough to warrant his selection to the 40-man roster ahead of the regular season.
