The Red Sox traded Murphy to the White Sox on Tuesday in exchange for Ronny Hernandez, Bob Nightengale of USA Today reports.

Murphy was effective as a big-league reliever in 2025, finishing the regular season with a 3.12 ERA and 1.18 WHIP across 34.2 innings. The White Sox aren't working with much depth in their bullpen, so the 27-year-old left-hander could see regular work in high-leverage opportunities with his new organization.

The Angels selected Urena's contract from Triple-A Salt Lake on Tuesday.

The right-hander spent most of the 2025 campaign at Double-A Rocket City, where he had a 4.33 ERA, 1.35 WHIP and 121:74 K:BB across 139.1 innings. Urena moved up to Triple-A for his final outing of the season and could be back at the highest level of the minors to begin 2026.

The Pirates selected Brannigan's (shoulder) contract from Double-A Altoona on Tuesday, Alex Stumpf of MLB.com reports.

Brannigan slashed .225/.329/.358 across 237 plate appearances at Double-A Altoona in 2025 before suffering a shoulder injury in June that required season-ending surgery. The 24-year-old infielder will join Pittsburgh's 40-man roster to ensure he remains with the organization past the Rule 5 Draft in December, though he shouldn't be expected to appear in the big leagues in 2026.

The Pirates selected Valdez's contract from Double-A Altoona on Tuesday, Francys Romero of BeisbolFR.com reports.

Valdez split his time between High-A and Double-A ball in 2025, slashing .284/.375/.521 with 27 homers, 87 RBI and 76 runs scored between the two levels. His impressive performance will grant him a place on Pittsburgh's 40-man roster heading into the 2026 campaign, but he's likely to begin the year at Double-A Altoona or Triple-A Indianapolis.

The Astros selected Ullola's contract from Triple-A Sugar Land on Tuesday.

The move adds Ullola to the 40-man roster and protects him from next month's Rule 5 Draft. Ullola spent the entirety of the 2025 campaign at Sugar Land, finishing with a 3.88 ERA and 131:78 K:BB over 113.2 innings. The 23-year-old will compete for an Opening Day roster spot, but a career 15.6 percent walk rate in the minors suggests more seasoning is needed.

The Astros designated Urias for assignment Tuesday.

The transaction frees up a spot on the 40-man roster for the addition of Miguel Ullola. Urias is projected to make more than $4 million in his final year of arbitration eligibility, which the Astros felt was too much. The 31-year-old is a career .257/.321/.403 hitter and capable defender at second and third base, so he shouldn't have difficult landing a major-league contract this winter, assuming he clears waivers and becomes a free agent.

King rejected the Padres' $22.025 million qualifying offer Tuesday, Alden Gonzalez of ESPN.com reports.

King was limited to 15 regular-season starts in 2025 due to shoulder and knee issues, but it's still not a surprise he elected to turn down the qualifying offer. King posted a 3.44 ERA over 73.1 innings last year and had a 2.95 ERA during his first season as a full-time starter in 2024. Extending the qualifying offer will net the Padres a compensatory draft pick, assuming he doesn't re-sign with the team.

Diaz rejected the Mets' one-year, $22.025 million qualifying offer Tuesday, Alden Gonzalez of ESPN.com reports.

Diaz opted out of the two years and $38 million remaining on his contract with the Mets earlier this month, and now he has passed on the qualifying offer. Neither decision was a surprise, as the closer shouldn't have difficulty netting a big multi-year pact this winter. If he leaves the Mets, New York will receive a draft pick as compensation.

Spiers (elbow) was designated for assignment by the Reds on Tuesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Cincinnati needed a 40-man spot for one of its young prospects, and Spiers was a likely choice to be bounced given he's expected to miss most, if not all, of 2026. The right-hander made three appearances (two starts) in the majors this past season before undergoing Tommy John surgery at the end of July. Spiers has put up a 5.69 ERA and 1.57 WHIP over 117 career innings in the majors.

Suarez rejected the Phillies' one-year, $22.025 million qualifying offer Tuesday, Alden Gonzalez of ESPN.com reports.

By extending Suarez the qualifying offer, the Phillies will now obtain a draft pick if the left-hander signs with a new team in free agency. Suarez has never made 30 starts or thrown 160 innings in a big-league season, but he's been incredibly valuable nonetheless, collecting a 3.25 ERA since the start of the 2021 campaign.
