Tyler Gilbert’s latest turn with the White Sox has ended the way so many roster moves do in September: quietly, and with a little less drama than the transaction itself suggested.
Chicago designated the left-hander for assignment earlier this week to make room on the 40-man roster for Tommy Pham. Gilbert cleared waivers, and the White Sox outrighted him to Triple-A Charlotte today.
Because he has already been outrighted twice in his career, he could have turned down the assignment. Instead, according to James Fegan of the Chicago Sun-Times, he is staying in the organization.
That makes sense at this point in the calendar, since he would not have been eligible to pitch in the postseason for a new team anyway.
Gilbert’s path has been a long one. The Phillies took him in the sixth round of the 2015 draft, and after years in the minors with Philadelphia and a short run in the Dodgers organization, he finally reached the majors with Arizona in 2021.
That debut became the stuff of instant baseball trivia: Gilbert threw a no-hitter in his first big league start. The rest of his time with the Diamondbacks was much more ordinary, as he logged a 4.32 ERA and 4.78 SIERA across 91 2/3 innings in 28 games, including 13 starts, from 2021-23.
After the 2023 season, Gilbert hit free agency and signed a minor league deal with Cincinnati. He never got a major league look with the Reds, but his work at Triple-A Louisville eventually brought him back to the Phillies, who traded for him and used him in a handful of late-season appearances in 2024.
That winter, Philadelphia designated him for assignment and sent him to the White Sox, where he turned in what was probably his best stretch in the majors. No no-hitter this time, but he did work a career-high 51 innings despite a couple of injured list stints.
He finished with a career-best four wins and five holds, and he picked up his first save as well. His 3.88 ERA outpaced a 4.31 SIERA, so there was likely a bit of good fortune mixed in, but he still looked like a useful low-leverage arm.
This season has gone in the opposite direction. Chicago optioned Gilbert after he allowed two runs in one inning on Opening Day.
His next call-up lasted just one game, and he was tagged for four runs in fewer than two innings. It took two months for him to get back to the majors, and after only two more appearances, a left shoulder impingement sent him to the injured list until August.
He returned for his fifth outing of the year this past weekend, then got designated for assignment two days later.
In six total innings for the White Sox in 2026, Gilbert has given up eight runs on 12 hits while striking out four of the 32 batters he has faced. His Triple-A numbers are better, though still hardly eye-catching: a 4.64 ERA and 4.52 xERA in 33 innings, with 31 strikeouts and 10 walks.
For now, Gilbert stays in the White Sox system as organizational depth. If he is not added back to the 40-man roster, he will be able to elect free agency after the season.

Luis Arraez Is Forcing A Phillies Tradeoff Fans Can't Ignore
Since joining the Phillies on Aug. 4, Luis Arraez has given the club exactly what it expected in one respect and a little less in another. The contact-heavy infielder has settled into a .288/.302/.396 line in Philadelphia, a step down from what he was doing earlier with the Giants, but his value has never really been about loud power or eye-catching exit velocity. It has been about putting the ball in play, and the Phillies have kept him in the middle of their daily puzzle because of that.
The harder part is what Arraez has done to the rest of the lineup. His arrival has forced defensive reshuffling, with Alec Bohm and Bryson Stott among the players taking on new responsibilities, and that kind of tradeoff always puts a roster under a little more strain. Arraezs production still carries the kind of profile that can swing with BABIP and the kind of luck that tends to even out over time, which leaves the Phillies weighing present fit against the version of him they believe is still in there.

Phillies Prospects Sudden Health Fight Put Baseball In Perspective
Gabriel Barbosas rise through the Phillies system had been one of those quieter prospect stories that starts far from the spotlight and builds one level at a time. The right-hander came up from Brazil, advanced through the minor league ladder in Philadelphias organization and was beginning to look like another arm worth tracking, the kind of development path teams and fans follow closely when the long season starts to thin the herd.
Now baseball has been shoved far into the background. Barbosa was diagnosed with Stage 3 colon cancer in 2026 while expecting his first child, and a GoFundMe has been set up to help cover medical and family expenses, organized by the Rockies scout who first signed him. It is the sort of news that turns a prospect report into something much more human, a reminder that the games next call-up can be fighting a far bigger battle away from the field. [Read more 🡒]
Phillies Suddenly Have A Real Late-Inning Trust Problem
Orion Kerkerings season has reached a point where every late-inning appearance feels heavier than the last. The right-hander has not given the Phillies the kind of dependable bridge work they expected, and after another rough outing against the Braves, his numbers have become hard to ignore, including a 4.12 ERA overall and a 12.27 mark over his last four appearances. For a bullpen built around getting through the most stressful outs, that kind of slide changes how a manager has to think about the back end of games.
Matt Gelb of The Athletic put the spotlight on the issue by noting the Phillies may need to rethink where Kerkering fits in the relief hierarchy. Alex McFarlane has been much steadier lately and is now making a case for the sort of high-leverage responsibilities that once looked like Kerkerings to lose. For a club trying to sort out its late innings, the question is no longer just who gets the ball, but who can be trusted when the game is on the line. [Read more 🡒]
