The Giants signed Houser to a two-year, $22 million contract with a club option for 2028 on Tuesday, Jeff Passan of ESPN.com reports.

Houser showed more velocity and put together a bounce-back season in 2025, collecting a 3.31 ERA and 92:38 K:BB over 125 innings covering 21 starts between the White Sox and Rays. The veteran right-hander will turn 33 in February and lands in a favorable home environment in Oracle Park, but Houser's fantasy value will remain limited because of a lack of strikeouts.

Santos signed a minor-league contract with the Giants on Tuesday that includes an invitation to spring training, Francys Romero of BeisbolFR.com reports.

Santos first reached the majors with the Giants in 2021 before being traded to the White Sox three years ago. The 26-year-old had a tough time with injuries the past two seasons with the Mariners, making a total of only 16 appearances due to arm and knee problems. Santos is recovered from April arthroscopic right knee surgery and has a chance to win a spot in the Giants' bullpen.

The Giants signed Foley (shoulder) to a one-year contract Tuesday.

Foley was non-tendered by the Tigers last month after missing most of the 2025 season following arthroscopic right shoulder surgery. He's not expected to be ready to pitch with the big club until midseason, per Susan Slusser of the San Francisco Chronicle. Foley will remain under team control through 2028, so it could be a sneaky signing if he can return to pre-surgery form. The 30-year-old led the Tigers with 28 saves during his last full season in 2024, posting a 3.15 ERA and 46:20 K:BB over 60 regular-season innings.

The Mariners signed Knizner to a one-year contract Tuesday.

Knizner saw 88 plate appearances this past season with the Giants, putting up a .598 OPS. A career .211/.281/.316 hitter over parts of seven big-league seasons, Knizner is poised to open the 2026 season as the Mariners' backup catcher behind star Cal Raleigh.

The Kiwoom Heroes of the Korea Baseball Organization signed Wiles to a one-year, $910,000 contract Tuesday, Yoo Jee-ho of Yonhap News Agency reports.

Wiles made one appearance with Atlanta in 2025, allowing three runs in an inning of work. The 27-year-old will get an opportunity to be part of the Heroes' rotation.

The Kiwoom Heroes of the Korea Baseball Organization signed Brooks to a one-year, $700,000 contract Tuesday, Yoo Jee-ho of Yonhap News Agency reports.

He can earn an additional $150,000 in incentives. Brooks has hit just .136/.208/.212 in 37 games at the big-league level and will now try his luck overseas.

Rodon (elbow) is in the second week of his throwing program, Bryan Hoch of MLB.com reports.

Working his way back from surgery in mid-October to remove loose bodies and shave down a bone spur in his left elbow, Rodon most recently made 30 throws from 60-75 feet. The southpaw anticipates making some Grapefruit League starts, but he will begin the season on the injured list and isn't expected to make his regular-season debut for the Yankees until late April or early May.

The Cubs re-signed Thielbar to a one-year contract Tuesday, Jesse Rogers of ESPN.com reports.

Thielbar collected a 2.64 ERA and 56:13 K:BB over 58 regular-season innings for the Cubs in 2025. Left-handed batters hit just .161/.211/.276 off the southpaw. Thielbar -- who will turn 39 in January -- will help set up from the left side in the Cubs' bullpen.

Perez suffered a left thumb injury Sunday while playing in the Venezuelan Winter League, Al Son de la LVBP reports.

Perez posted a video on Instagram of himself working out and he didn't seem to be overly affected by the injury, so it seems to be a day-to-day situation that shouldn't affect his availability for spring training. The 35-year-old Perez has gone 6-for-29 with two home runs for Leones del Caracas in winter ball thus far.

Phillies president of baseball operations Dave Dombrowski said Tuesday that the team plans to have Brandon Marsh, Crawford and Adolis Garcia as its primary outfielders in 2026, Matt Gelb of The Athletic reports.

The Phillies officially announced the Garcia signing Tuesday, and Dombrowski intimated that another notable addition to the club's outfield is unlikely. Crawford will still have to show in spring training that he's ready to take over as the Phillies' primary center fielder, but the team is positioning him to be the guy at that position. There are questions about Crawford's defense in center field, but his bat looks ready after he slashed .334/.411/.452 with seven home runs and 46 stolen bases at Triple-A Lehigh Valley in 2025 as a 21-year-old.
