The Rangers outrighted Diaz to Triple-A Round Rock on Sunday.

EDGE Analysis

After signing a one-year deal with Texas in December, Diaz entered spring training with a chance to stake his claim to the closer job in an unsettled bullpen. The right-hander's lack of command during spring training ultimately resulted in him not only falling short of a high-leverage role, but a spot on the 40-man roster. He'll remain in the Texas organization after drawing no interest on the waiver wire, having yielded eight earned runs on three hits and four walks over 1.2 innings in the Cactus League.

The Rangers designated Diaz for assignment Friday.

EDGE Analysis

Diaz entered spring training with a chance at winning Texas' closer job, but he was shelled and allowed eight earned runs on three hits and four walks across 1.2 innings and three relief appearances. He faced 13 batters and retired just five, striking out one. With Diaz out of the picture, Robert Garcia and Chris Martin are the favorites for saves for the Rangers.

Rangers manager Skip Schumaker said Wednesday that Diaz has a chance to see saves for the club this season, but the manager wants to see how the former Reds closer looks in spring training games first, Jeff Wilson of AllDLLS.com reports.

EDGE Analysis

Schumaker listed Robert Garcia and Chris Martin as the initial favorites to close games, but he left the door open for Diaz. The 29-year-old righty notched 75 saves for Cincinnati from 2022-24, but he fell apart in 2025, posting an 8.15 ERA and 1.53 WHIP over 17.2 innings between three different teams. It's a good opportunity for Diaz to re-establish himself on a team lacking bullpen clarity, but he has a lot to prove before fantasy managers can trust him again.

Diaz signed a one-year contract with the Rangers on Friday, Jeff Passan of ESPN.com reports.

EDGE Analysis

Diaz took a massive step in the wrong direction this past season, going from recording 28 saves with the Reds in 2024 to finishing the 2025 campaign with an 8.15 ERA and 1.53 WHIP over 17.2 innings in the big leagues. He'll get another chance to turn things around with the Rangers, though he'll likely need to display some consistency before the team considers using him in high-leverage situations regularly.

Diaz elected to become a free agent Thursday, David O'Brien of The Athletic reports.

EDGE Analysis

Diaz had been booted off Atlanta's 40-man roster, and he will exercise his right to free agency rather than accepting an outright assignment. The former closer held an 8.15 ERA and 1.53 WHIP over 17.2 innings at the big-league level in 2025 and might have to accept a minor-league contract this offseason.

Diaz cleared waivers Wednesday and was sent outright to Triple-A Gwinnett.

EDGE Analysis

Diaz bounced between Cincinnati, Los Angeles and Atlanta in 2025, finishing the regular season with an 8.15 ERA and 1.53 WHIP through 17.2 MLB innings. He'll likely need to prove himself in the minors next season before getting another shot in the big leagues.

Atlanta optioned Diaz to Triple-A Gwinnett on Tuesday.

EDGE Analysis

Diaz has made three relief appearances after being claimed off waivers by Atlanta on Sept. 7, yielding four runs (three earned) with a 5:5 K:BB. The former Reds closer holds an 8.18 ERA over 18 relief outings in the big leagues this season.

Atlanta claimed Diaz off waivers Sunday, David O'Brien of The Athletic reports.

EDGE Analysis

The right-hander was designated for assignment by the Dodgers on Thursday, and it's not a surprise he was claimed off waivers given his previous success in the majors. Diaz has struggled to a 7.80 ERA in 15 outings in the big leagues with the Dodgers and Reds this season, and he hasn't been much better at Triple-A with a 6.08 ERA.

The Dodgers designated Diaz for assignment Thursday, Fabian Ardaya of The Athletic reports.

EDGE Analysis

Diaz lost his 40-man roster spot to make room for Ben Rortvedt, who was selected by the Dodgers Thursday as Will Smith battles a hand injury. Diaz had a 4.15 ERA across 8.1 innings with the Dodgers since making his team debut July 22. He also had a 8.10 ERA across 10 innings for Triple-A Oklahoma City since being dealt by the Reds at the end of May.

The Dodgers optioned Diaz to Triple-A Oklahoma City on Wednesday.

EDGE Analysis

The move corresponds with the Dodgers recalling Paul Gervase from Triple-A. Diaz has struggled out of the bullpen in three of his last outings, allowing five runs on five hits and two walks while striking out five across 4.2 innings over that span. He'll look to regain his control in Triple-A and could return to the majors should the Dodgers need right-handed depth out of the bullpen.
