May signed a one-year contract with the Cardinals on Saturday that includes a mutual option for 2027, Jeff Passan of ESPN.com reports.

May set a new career high with 132.1 innings pitched between the Dodgers and Red Sox in 2025, though his 4.96 ERA and 1.42 WHIP in the regular season both marked significant regression from previous years. Despite his recent struggles, the 28-year-old righty should have little trouble claiming a spot in a Cardinals rotation that doesn't feature much depth following the departure of Sonny Gray.

Frasso (undisclosed) signed a minor-league contract with the Dodgers on Saturday, Aram Leighton of JustBaseball.com reports.

After turning in a 5.49 ERA and 1.58 WHIP over 77 innings at Triple-A Oklahoma City this past season and being non-tendered by the Dodgers in November, Frasso will officially return to the organization for 2026. The 27-year-old is still waiting on his first promotion to the majors, but he will likely need to show significant improvement in the minors before getting called up for his MLB debut.

Polanco signed a two-year, $40 million contract with the Mets on Saturday, Will Sammon of The Athletic reports.

After posting a career-worst .651 OPS in 2024, Polanco rebounded to the tune of a .265/.326/.495 slash line while logging 26 homers, 78 RBI and 64 runs scored over 524 regular-season plate appearances in 2025. He'll now help bolster the Mets' offense, though he's unlikely to continue playing at the keystone, considering the team traded for Marcus Semien in November. New York may instead utilize Polanco mainly as a DH or shift him to first base to make up for the loss of Pete Alonso.

The Nationals and Gray (elbow) avoided arbitration by agreeing to a one-year, $1.35 million contract Friday, Andrew Golden of The Washington Post reports.

Gray was limited to three rehab starts this season as he returned from UCL surgery and will receive the same salary he got in 2025. The right-hander is expected to be ready to go at the start of spring training, though he will likely face workload restrictions in 2026 after throwing a combined 35 innings over the previous two seasons.

The Diamondbacks designated Jarvis for assignment Friday.

The transaction frees up a 40-man roster spot for Michael Soroka, whose signing was officially announced Friday. Jarvis has a 3.69 ERA over 105 innings at the major-league level, but that's come with an unappetizing 71:52 K:BB.

The Dodgers claimed Siani off waivers from Atlanta on Friday.

Siani has gone from St. Louis to Atlanta and now to the defending champs via waivers this offseason. The speedster is a terrific defensive center fielder but has slashed just .221/.277/.270 at the big-league level and spent most of the 2025 season in the minors. Siani has minor-league options remaining, and if he's still in the Dodgers organization on Opening Day, it will likely be at Triple-A Oklahoma City.

The Marlins signed Morel to a one-year contract Friday, Ken Rosenthal of The Athletic reports.

The Marlins plan to use Morel at first base, a position he has never played before. Given the team's lack of other options at first base, he could be the regular there if his defense is at least adequate. Morel flashed loads of promise earlier in his career, particularly in 2023 with the Cubs when he posted a .821 OPS with 26 home runs over only 429 plate appearances. He has just a .651 OPS since then, and his strikeout rate spiked to 35.7 percent in 2025 with the Rays. Morel still makes loud contact when he connects (49.7 percent hard-hit rate, 14.8 percent barrel rate in 2025), and the Marlins will try to get him to cut down on the swing-and-miss. He will be arbitration eligible in 2027 and 2028.

Jones signed a minor-league contract with the Brewers on Thursday that includes an invitation to spring training, Adam McCalvy of MLB.com reports.

Jones slashed .145/.254/.258 across 71 plate appearances with the White Sox's Triple-A affiliate before being released by the club in May. He then signed a minor-league deal with the Astros, but an injury forced him to miss most of the remainder of the season. Now with the Brewers, the 27-year-old projects to remain a minor-league depth piece.

Baddoo signed a one-year contract with the Brewers on Thursday, Ken Rosenthal of The Athletic reports.

Baddoo spent the majority of the 2025 campaign with the Tigers' Triple-A affiliate, where he slashed .281/.385/.481 with 15 homers, 48 RBI, 73 runs scored and 25 steals over 103 games. The 27-year-old outfielder will have a chance to earn a spot on Milwaukee's Opening Day roster during spring training, though it's unlikely he lands a starting job over Isaac Collins, Sal Frelick and Jackson Chourio.

The Cubs signed Milner to a one-year, $3.75 million contract Thursday, Mark Feinsand of MLB.com reports.

Milner will be reunited with manager Craig Counsell, who he pitched for in three of his four years with the Brewers. The left-handed reliever spent the 2025 campaign with the Rangers, collecting a 3.84 ERA, 51.4 percent groundball rate and 58:21 K:BB over 70.1 frames.
