The Cubs claimed Rolison off waivers from the White Sox on Wednesday, Bruce Levine of 670TheScore.com reports.

It's the fourth organization since November for Rolison, who posted a 7.02 ERA and 25:20 K:BB over 42.1 innings with the Rockies in 2025. The left-hander will compete for a spot in the Cubs' bullpen, but he does have minor-league options remaining.

Angels general manager Perry Minasian said Wednesday during a conference call announcing the signing of Yates that the reliever will have to earn closing opportunities, Taylor Blake Ward of The Sporting Tribune reports.

Minasian did point out multiple times that Yates' closer experience as well as a past relationship with pitching coach Mike Maddux were important factors in the Angels giving the veteran hurler a one-year, $5 million contract. The Angels also added former closer Jordan Romano this offseason and have Ben Joyce (shoulder) and Robert Stephenson (elbow) coming back from injury. All four relievers are candidates for saves, and Minasian noted that the decision as to who will close games will be up to manager Kurt Suzuki.

The Rockies claimed Thompson off waivers from the Reds on Wednesday.

Thompson signed a one-year, $1.3 million split contract with the Reds in November, but he was booted off their 40-man roster in December and is now headed to Colorado. He's been used almost exclusively in relief over the past three seasons, but Thompson does have past starting experience, so the Rockies could consider him in a swingman role.

The Reds outrighted Richardson to Triple-A Louisville on Wednesday.

Richardson is no longer on the 40-man roster but will remain in the organization after passing through waivers unclaimed. The right-hander finished 2025 with a 4.54 ERA, 1.54 WHIP and 30:21 K:BB across 37.2 regular-season innings for Cincinnati.

The Orioles claimed Luciano off waivers from the Pirates on Wednesday, Francys Romero of BeisbolFR.com reports.

Luciano has managed just a .217/.286/.304 batting line over 41 games in the majors and hasn't been great at the Triple-A level, either, slashing .227/.351/.401. The former top prospect is still just 24, so the Orioles felt he was worth a flier. Luciano -- who does not have minor-league options remaining -- was moved to left field at Triple-A Sacramento in the Giants organization in 2025 after previously playing shortstop.

The Rays signed Olivares to a minor-league contract Wednesday that includes an invitation to spring training, Marc Topkin of the Tampa Bay Times reports.

A career .254/.306/.407 hitter over parts of five big-league seasons, Olivares spent the 2025 season with the Orix Buffaloes in Japan. The 29-year-old will compete for a roster spot with the Rays but is likely destined to begin the 2026 season at Triple-A Durham.

The Guardians re-signed Nunez to a minor-league contract Wednesday that includes an invitation to spring training.

Nunez went 2-for-7 at the plate during his brief time with the Guardians in 2025 and slashed .176/.330/.349 at Triple-A Columbus. He's likely headed back to Columbus to begin the 2026 season.

Wilson is considering retirement, Ken Rosenthal and Will Sammon of The Athletic report.

The 38-year-old would consider returning only if he receives what he deems a fair contract for a World Series contender. Wilson is coming off a quality 2025 campaign with the Red Sox, having collected a 3.35 ERA and 57:20 K:BB over 48.1 regular-season innings. Boston is reportedly interested in re-signing the veteran lefty.

Roa signed a minor-league contract with the Astros on Dec. 20.

Roa made his MLB debut with the Marlins in 2025, throwing three scoreless innings while striking out three batters and walking three. Most of his time was spent in Triple-A, where he posted a 2.83 ERA and 1.10 WHIP across 60.1 frames. The 26-year-old righty is likely to report to Triple-A Sugar Land to begin the 2026 campaign, though he could join the Astros' bullpen at some point if he continues to thrive in the minors.

The Giants designated Dean for assignment Tuesday, Susan Slusser of the San Francisco Chronicle reports.

Dean arrived in San Francisco in November via waiver claim, but he'll now depart the 40-man roster to make room for Tyler Mahle. Dean slashed .289/.378/.431 and stole 27 bases across 347 plate appearances with the Dodgers' Triple-A affiliate in 2025, and he's likely to work as minor-league depth again in 2026.
