RHP Mitch White
This has always felt like an obvious choice, but yet Mitch White still remains on the roster.
After landing in Toronto via trade with the Dodgers at last year's deadline, White showed some occasional promise but never got a chance to branch off of that in the early goings of the 2023 campaign, as he sat on the shelf for the first few months of the year. On the road back to the big leagues, he struggled mightily in his rehab outings and has since proven to be an arm that is still unreliable.
The 28-year-old had pieced together a few solid outings in a row, throwing 6.1 innings of one-run ball with six strikeouts across five appearances from June 13 to June 30. On July 7 against the Tigers, he came in and threw 1.2 innings and seemed to be turning a corner before Sunday's game against the Diamondbacks.
In his July 16 outing against Arizona, White walked three batters and allowed three runs to score while failing to pitch in a full inning on the mound. This is in line with what we saw of him throughout the majority of last season and it's hard to see him remaining with the big league club for much longer. While there's been some positive signs here and there, a club with sights set on a playoff berth can't keep an arm like White’s around.
What complicates his situation even further is the fact that he is out of minor league options. White would need to be designated for assignment before the Blue Jays could even think about sending him to the minors. Perhaps he could be used as a filler piece in a potential trade around the deadline, as this experiment just doesn't seem to be working out.
