Keller allowed two runs on four hits over two innings of relief in Friday's 8-1 loss to the Diamondbacks. He struck out three.
Keller joined the Cubs over the winter on a minor-league deal, but he did enough in camp to warrant a look as a long reliever on the MLB roster. He was able to make his team debut in mop-up duty Friday, and while Arizona managed some solid contact, he at least tallied three strikeouts in his two frames. The righty figures to work mostly in low-leverage spots for Chicago, at least for the time being, giving him limited fantasy appeal.

Cubs' Brad Keller: Expected to make team
Rotowire
The Cubs are likely to add Keller to their major-league roster rather than allow him to exercise the opt-out clause in his minor-league contract, Patrick Mooney of The Athletic reports.
Keller has "opened eyes" in Cubs camp with his velocity jump and mechanical improvements, per Mooney, so the team doesn't want to let him get away. The big righty has allowed four runs with a 6:1 K:BB over seven innings during Cactus League play. Keller seems likely to serve in a long relief role initially for the Cubs.

Rotowire
Keller cleared waivers Thursday and elected to become a free agent.
Keller was cast off the Red Sox's 40-man roster Tuesday after turning in a 5.84 ERA and 1.62 WHIP across 24.2 innings with the team.

Rotowire
The Red Sox designated Keller for assignment Tuesday, Pete Abraham of The Boston Globe reports.

Brad Keller: Becomes free agent
Rotowire
Keller elected free agency Tuesday, Alex Speier of The Boston Globe reports.
Keller's tenure in the big leagues afforded him the ability to decline an option to Triple-A Worcester and elect free agency, and the veteran right-hander has exercised that right and will move on from the Red Sox. He holds a 5.30 ERA and 30:13 K:BB over 37.1 innings at the big-league level in 2024.

The Red Sox optioned Keller to Triple-A Worcester on Monday, Chris Henrique of Beyond the Monster reports.

Red Sox's Brad Keller: Joins Boston
Rotowire
Keller signed a one-year contract with the Red Sox on Sunday, Mac Cerullo of the Boston Herald reports.
After clearing waivers upon being designated for assignment by the White Sox last week, Keller elected free agency and quickly caught on with a new club on a big-league deal. Keller is expected to be available out of the bullpen for Sunday's game against the Brewers and should serve as a long-relief option for the duration of his stay with Boston. Prior to being cut by the White Sox, Keller made five appearances (two starts) and pitched to a 4.86 ERA and 1.38 WHIP across 16.2 innings.

White Sox's Brad Keller: Moved off 40-man roster
Rotowire
The White Sox designated Keller for assignment Sunday, James Fegan of SoxMachine.com reports.
Keller was tagged with the loss Saturday versus the Yankees, giving up six runs (five earned) on seven hits, including four homers, and he'll now be placed on waivers. The right-hander owns a 4.86 ERA over 16.2 innings in five appearances, including two starts, with Chicago in 2024, so it's plausible that another organization could claim him. The transaction opens a spot on the Chicago's 40-man roster, while Keller's spot on the major-league roster will likely be filled by Dominic Leone (back), who's slated to be activated from the 15-day injured list in the near future. It's unclear who will replace Keller in the starting rotation, though Michael Soroka projects as a logical replacement for the time being.

White Sox's Brad Keller: Can't keep ball in yard Saturday
Rotowire
Keller (0-2) took the loss Saturday as the White Sox were downed 6-1 by the Yankees, coughing up six runs (five earned) on seven hits -- including four home runs -- and a walk over four-plus innings. He struck out four.
The right-hander served up a pair of homers to Juan Soto in the first and fifth innings, with Jose Trevino and Giancarlo Stanton taking Keller deep in between. Troubles keeping the ball in the park are nothing new for Keller, as he got tagged for 35 home runs over 273.1 innings in 2021-22 while with the Royals. Keller's spot in the White Sox's rotation is by no means secure, but if he takes another turn at home next week against the Orioles, he'll carry a 4.86 ERA and 1.38 WHIP to the mound.

White Sox's Brad Keller: Used in long relief
Rotowire
Keller allowed one earned run on five hits and no walks with no strikeouts across three innings Tuesday against the Rays. He did not factor into the decision.
Keller pitched as a traditional starter May 1, but he was shifted back to the bullpen after Mike Clevinger was promoted to the majors. Keller pitched effectively in his return to relief and followed Michael Soroka into the game. However, due to his lack of strikeouts and relatively low win potential, Keller isn't likely to generate much fantasy intrigue.

White Sox's Brad Keller: Handed loss Friday
Rotowire
Keller (0-1) allowed three runs on five hits and two walks over 4.2 innings Friday, striking out five and taking a loss against St. Louis.
Keller coughed up a pair of runs in the first inning but kept the Cardinals in check until he was charged with another run in the fifth. He forced 12 swinging strikes but needed 102 pitches to get through 4.2 frames. Keller registered a 4.50 ERA across three starts with Triple-A Charlotte before his promotion to the MLB level, and it's unclear if he'll stick in the White Sox rotation.

White Sox's Brad Keller: Gets start Friday
Rotowire
Keller is scheduled to start Friday's game against the Cardinals at Busch Stadium.
Keller was called up from Triple-A Charlotte on Sunday and proceeded to make his White Sox debut as a reliever Monday, when he tossed 1.2 scoreless innings against the Twins. The White Sox haven't indicated that Keller will be joining the rotation on a permanent basis, as the team might have just wanted to build in an extra day of rest for Erick Fedde, who will take the hill Saturday after tossing 8.1 innings and 108 pitches in his most recent outing last Sunday versus the Rays. Keller will be taking the mound Friday on three days' rest, so he could face a light workload, even though he had worked five-plus innings in each of his three starts with Charlotte prior to his call-up.

White Sox's Brad Keller: Gets call-up from Triple-A
Rotowire
The White Sox selected Keller's contract from Triple-A Charlotte on Sunday.
Keller was built up slowly in spring training while he completed his recovery from offseason thoracic outlet syndrome surgery, but he was deemed ready to go for the start of the Triple-A season. He made three starts for Charlotte prior to his call-up, working at least five innings each time out while pitching to a 4.50 ERA, 1.38 WHIP and 14:6 K:BB in 16 innings. Keller is expected to give the White Sox a multi-inning option out of the bullpen for the time being, but he could eventually emerge as a candidate for the big-league rotation if back-end starter Chris Flexen fails to perform well enough to hold down that role on a more permanent basis.

Keller had been at extended spring training following thoracic outlet syndrome surgery over the offseason, but he's now ready to join an affiliate. It's possible the longtime Royal will get a look in a White Sox rotation that's used only four starters so far, although Mike Clevinger will probably be ready before him.

White Sox's Brad Keller: Had thoracic outlet surgery
Rotowire
Keller underwent thoracic outlet syndrome surgery over the offseason, Daryl Van Schouwen of the Chicago Sun-Times reports.
Keller dealt with thoracic outlet syndrome symptoms on a couple occasions last season while with the Royals and evidently at some point opted for surgery. He inked a minor-league deal with the White Sox last week and "threw the ball really well" during a recent live batting practice session, per manager Pedro Grifol. Keller is expected to begin the season at Triple-A Charlotte but could become an option for Chicago's rotation before long.
