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

EDGE Analysis

Keller coughed up five runs (three earned) over four innings in an extended relief appearance Monday versus the Blue Jays. He wasn't going to be available for at least a couple days, so the Red Sox have elected to summon another reliever in his spot.

The Red Sox selected Keller's contract from Triple-A Worcester on Monday, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Keller rejected an option to Worcester earlier this month before re-signing with Boston on a minor-league deal. He's now back in the big leagues to provide a fresh arm for Boston's bullpen.

The Red Sox re-signed Keller to a minor-league contract Tuesday, Chris Hatfield of SoxProspects.com reports.

EDGE Analysis

Keller elected free agency Tuesday, Alex Speier of The Boston Globe reports.

EDGE Analysis

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, Jen McCaffrey of The Athletic reports.

EDGE Analysis

Keller made one extended relief appearance during his most recent stint in the majors, allowing three runs over four frames and taking a loss against the Astros on Saturday. He will likely re-enter Worcester's rotation.

Keller (0-3) took the loss against the Astros on Saturday, allowing three runs on six hits and two walks with six strikeouts across four innings.

EDGE Analysis

In his first major-league appearance since June 23, Keller served as a bulk reliever and surrendered three runs on homers by Yordan Alvarez and Alex Bregman. The 29-year-old has yielded eight long balls across 37.1 major-league innings this season with a 5.30 ERA, 1.45 WHIP and 30:13 K:BB.

The Red Sox recalled Keller from Triple-A Worcester on Friday, Alex Speier of The Boston Globe reports.

EDGE Analysis

Keller has allowed 10 runs over 16.2 frames during his time in Boston this season. He would seem to be a good bet to eat up some innings Saturday versus the Astros in what could be a bullpen game for the Red Sox.

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

EDGE Analysis

Keller has allowed 10 runs over 16.2 innings as a low-leverage reliever for the Red Sox. He's being replaced by a fresh arm after he threw 31 pitches and allowed three runs over one inning in Sunday's 7-4 win over the Reds.

Keller signed a one-year contract with the Red Sox on Sunday, Mac Cerullo of the Boston Herald reports.

EDGE Analysis

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.

Keller cleared waivers Wednesday and elected to become a free agent, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Keller was DFA'd by the White Sox on Sunday after posting a 4.86 ERA and 1.38 WHIP across 16.2 innings, and he'll now try his luck in the open market rather than accepting an outright assignment to Triple-A Charlotte. The 28-year-old righty has not found much consistent success throughout his past few seasons in the majors, but he should have no problem securing at least a minor-league deal with another team in need of rotation depth.
