Diaz began his throwing program at home in Puerto Rico in order to get off to a better start in the 2025 season, Mark Sheldon of MLB.com reports. "I started throwing or loosening up my arm at the end of October," Diaz said. "I feel like since then, I've been able to work on my throwing and get my arm loose and ready for Spring Training. I think just my physique and how I've been able to work as well has been much better."

Diaz's ERA soared like a jet airplane early in the season, peaking at 7.47 after a terrible outing against the Dodgers in May. Over the final four months of the season, Diaz posted a 2.83 ERA and 1.14 WHIP, though his K% remained lower than his previous seasons. The Reds haven't added any competition to the back end of the bullpen to date, so it appears that Diaz will get a full chance to redeem himself to start 2025.

The Guardians signed Pint to a minor-league contract Wednesday.

The No. 4 overall pick in the 2016 First-Year Player Draft, Pint has failed to live up to expectations, in large part due to an inability to find the strike zone. He made five appearances with the Rockies over the last two seasons, allowing nine runs with a 7:8 K:BB over 3.2 frames. He'll be in minor-league camp during spring training and likely begin the 2025 season at Triple-A Columbus.

The Guardians designated Avila for assignment Wednesday.

The transaction clears a spot on the 40-man roster for the addition of Paul Sewald. Avila, 28, held a 3.81 ERA and 82:36 K:BB over 82.2 regular-season innings for the Guardians in 2024. There might be interest in Avila via trade or waivers, but his lack of minor-league options will limit his appeal.

The Guardians signed Sewald to a one-year, $6 million contract with a $10 million mutual option for 2026 on Wednesday, Zack Meisel of The Athletic reports.

He'll get a $1 million buyout if the mutual option isn't exercised, bringing the total guarantee to $7 million. Sewald missed some time with injury and lost his closer job with the Diamondbacks in 2024, ultimately finishing with a 4.31 ERA and 43:10 K:BB over 39.2 innings. However, from 2021 to 2023 he held a 2.95 ERA and had a 33.9 percent strikeout rate. Sewald will help set up for Emmanuel Clase in Cleveland.

The Blue Jays signed Lovelady to a minor-league contract Wednesday that includes an invitation to spring training, Keegan Matheson of MLB.com reports.

Lovelady posted a 4.46 ERA and 1.31 WHIP over 34.1 innings between the Cubs and Rays in 2024. The left-handed reliever has limited lefty hitters to a .232/.312/.342 batting line in his career and will compete for a spot in the Blue Jays' bullpen.

Trivino (elbow/shoulder) threw a bullpen session for interested teams Tuesday, Pat Ragazzo of SI.com reports.

The Yankees, Dodgers, Guardians, Cubs, Giants, Reds and Royals were among the clubs in attendance and "came away impressed" with Trivino, who got his sinker up to 94 mph, per Ragazzo. Trivino hasn't pitched in the majors since 2022 while working his way back from Tommy John surgery and had to have a rehab assignment shut down in September due to a shoulder issue, but it would appear he's healthy now.

The Athletics traded Klein to the Mariners on Tuesday in exchange for international slot money.

After the trade, Klein was added to Seattle's 40-man roster. The right-hander was designated for assignment Friday, but he had the tools to drive interest of other clubs. The Mariners will be the hard thrower's third ball club after beginning his career with the Royals.

The White Sox designated Marinaccio for assignment Tuesday, Daryl Van Schouwen of the Chicago Sun-Times reports.

The club needed to free up a spot on its 40-man roster with the signing of Martin Perez becoming official. Marinaccio was a waiver claim late last season and hasn't made an appearance for the White Sox. The 29-year-old holds a 3.22 ERA and 137:61 K:BB over 114.2 relief innings at the big-league level and could draw interest via trade or waivers.

The Angels and Quijada avoided arbitration by agreeing to a $1.075 million contract Tuesday.

The deal also includes a $3.75 million club option for 2026. Quijada, 29, has missed much of the last two seasons while recovering from Tommy John surgery, but he returned in late July this past season and posted a 3.26 ERA and 24:17 K:BB over 19.1 innings. He could see some high-leverage relief work for the Angels in 2025.

The Dodgers reached a contract agreement with Yates on Tuesday, Bob Nightengale of USA Today reports.

Just a couple days after signing the top free-agent relief arm in Tanner Scott, the Dodgers have further fortified their bullpen with the addition of Yates. Slated to turn 38 in March, Yates collected a microscopic 1.17 ERA, 0.83 WHIP and 85:28 K:BB over 61.2 innings while notching 33 saves for the Rangers in 2024. It's not an ideal landing spot from a fantasy perspective, as he will have lots of competition for saves in the Dodgers' bullpen.
