The Orioles claimed White off waivers from the Marlins on Monday.

White made his major-league debut with Miami this past season but was tagged for five runs on one hit, four walks and a hit-by-pitch across two-thirds of an inning. He spent the bulk of the campaign with Triple-A Jacksonville, logging a 2.41 ERA, 1.21 WHIP and 62:31 K:BB across 56 frames. The 25-year-old will likely get a shot to break camp with Baltimore.

The Astros selected Munoz's contract from Triple-A Sugar Land on Monday.

Munoz was dropped from the Astros' 40-man roster shortly after Opening Day after he was knocked around for seven runs in four innings. However, he's earned his way back onto the roster after posting a 3.06 ERA and 76:21 K:BB over 53 innings at Sugar Land.

The Mariners claimed Mattson off waivers from the Pirates on Monday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Mattson posted a 2.45 ERA and 45:19 K:BB over 47.2 innings in 2025, but he stumbled in 2026 with a 5.35 ERA and 36:18 K:BB over 38.2 frames. The 31-year-old will look to fill a middle relief role in Seattle.

Blue Jays general manager Ross Atkins said last week of Tiedemann that the team is "thinking of him as a reliever" heading into the 2027 season, Shi Davidi of Sportsnet.ca reports.

Tiedemann returned from a nearly two-year absence in 2026 due to Tommy John surgery and multiple setbacks, allowing one run with an 8:6 K:BB over six innings during his brief time in the big leagues. The 24-year-old boasts a 39.1 percent strikeout rate in the minors, but he's logged a total of just 152 innings since being drafted in 2021 because of myriad injuries.

The Red Sox exercised Whitlock's (leg) $8.25 million club option for 2027 on Sunday, Ari Alexander of 7 News Boston reports.

The right-hander pitched through a fractured right tibia down the stretch, but he still pitched well as he didn't give up an earned run in his final nine outings of the regular season. It's no surprise that Boston picked up the option after he posted a 1.72 ERA, 0.90 WHIP and 59:9 K:BB while recording four saves and 27 holds in 54 regular-season appearances.

Selby (shoulder) was reinstated from the 60-day IL, cleared outright waivers, and has been assigned to Triple-A Norfolk.

Selby underwent season-ending right shoulder surgery last July to repair his labrum and rotator cuff. He's not expected to be ready for Opening Day in 2027, though there's a good chance he'll be able to return to game action at some point during the summer. Selby didn't pitch at all last year, but he showed some promise in 2025 when he posted a 14:2 K:BB over 14 innings spanning 11 relief appearances with the Orioles while recording a 3.21 ERA and 1.29 WHIP.

Heuer cleared waivers and accepted an outright assignment to Triple-A Norfolk on Saturday.

Heuer ended the 2026 campaign in Triple-A before being designated for assignment. Rather than elect free agency, the veteran hurler has chosen to remain in Baltimore's organization. Heuer didn't pitch for the Orioles' big-league squad last year after being acquired in a trade with Milwaukee in early August. All of his MLB appearances in 2026 came with Cleveland, and he posted a 4.66 ERA, 1.76 WHIP and 6:5 K:BB across 9.2 innings in his eight outings.

The Royals exercised Gonsolin's $2.5 million club option for 2027 on Thursday.

Gonsolin missed almost all of the regular season while working his way back from Tommy John surgery, but he made it back in time to make one start for the big club in late September, during which he allowed five earned runs on four hits and three walks while fanning five batters in 2.2 innings. Despite struggling in his lone MLB outing, the Royals liked what they saw enough to pay $2.5 million to bring the 32-year-old righty back for 2027 and have him compete for a rotation spot.

The Mariners exercised Munoz's $9 million club option for 2027 on Thursday.

Munoz had a disappointing 2026 season by his standards, posting a 4.24 ERA, 1.22 WHIP and 89:24 K:BB over 57.1 innings. However, he's still a bargain at that price, and the Mariners will have another club option on Munoz for 2028. Munoz boasts a career 34.4 percent strikeout rate, and he'll be in line to serve as closer for Seattle again in 2027.

The Twins outrighted Banda (lat) to Triple-A St. Paul on Thursday, Dan Hayes of The Athletic reports.

The transaction frees a spo on the 40-man roster. Banda underwent left lat surgery in early July, but he expects to be ready for spring training. The southpaw has logged a 3.44 ERA and 144:67 K:BB over 149 regular-season innings covering the last three years.
