Groover was invited to major-league camp for spring training, Alex Weiner of Arizona Sports

Groover, the team's second-round selection in 2023, hit .281/.367/.474 last season with 10 home runs in 61 games over three minor-league stops. He missed significant time early with a broken wrist and eventually finished at Double-A Amarillo. Groover made up for lost reps in the Arizona Fall League, where he hit .339 in 18 games. He's spent time on the diamond at first, second and third base, but Groover needs to improve defensively if he's to stick at third. The soon-to-be 23-year-old showed good plate discipline in the minors, walking nearly as much as striking out.

The Mets signed Madrigal to a one-year, $1.35 million contract Friday, Joel Sherman of the New York Post reports.

He can earn an additional $500,000 in incentives. Madrigal has failed to pan out despite being the fourth overall pick in the 2018 Draft, particularly during his time with the Cubs when he managed just a .251/.304/.312 slash line in 616 PAs over the last three seasons. Injuries have been a problem, with a fractured hand costing him significant time in 2024. Madrigal can play second and third base and will attempt to win a reserve role in New York.

The Orioles designated Rivera for assignment Friday, Roch Kubatko of MASNSports.com reports.

The transaction frees up room on the 40-man roster for Luis Vazquez, who was acquired from the Cubs on Friday. Rivera slashed .313/.370/.578 in 73 plate appearances down the stretch with the Orioles last season and agreed to a one-year, $1 million contract earlier this offseason to avoid arbitration, but he'll now go through the waivers process.

Twins president of baseball operations Derek Falvey said during the team's Winter Meltdown fan event last week that Lewis will play third base this season, La Velle E. Neal III of the Minneapolis Star Tribune reports.

The Twins have toyed with the idea of moving Lewis to second base, and while he will get some reps at the keystone during spring training, the plan is for him to be the primary third baseman again in 2025. It's possible things change during the season, but fantasy managers shouldn't be counting on Lewis picking up second base eligibility. Brooks Lee might be the favorite to open the season as the Twins' second baseman, but Edouard Julien, Willi Castro and Austin Martin are also candidates to see action there.

The Red Sox signed Toro to a minor-league contract Tuesday that includes an invitation to spring training, Daniel Alvarez-Montes of ElExtraBase.com reports.

Toro slashed .240/.293/.350 with six homers in 94 games with the Athletics in 2024. The 28-year-old will compete for a reserve role this spring but will likely begin the 2025 season at Triple-A Worcester as utility depth.

The Rays and Walls avoided arbitration by agreeing to a one-year, $1.35 million contract with a $2.45 million club option for 2026 on Wednesday, Marc Topkin of the Tampa Bay Times reports.

The buyout on the option is $50,000, so Walls is guaranteed at least $1.4 million. Walls, 28, slashed only .183/.282/.248 over 84 games for the Rays in 2024 but remains an excellent defender and should get ample time at shortstop in 2025.

The Astros have extended Smith an invitation to big-league camp during spring training, Chandler Rome of The Athletic reports.

Acquired from the Cubs in the Kyle Tucker trade, Smith slashed .313/.396/.609 with seven home runs over 32 games across three levels in his pro debut in 2024 after being taken in the first round of last year's First-Year Player Draft. He's likely to begin the 2025 season at Double-A Corpus Christi, but the Astros will let him get his feet wet in major-league spring training.

Baty is expected to compete for the Mets' third base job during spring training, Joel Sherman of the New York Post reports.

With Pete Alonso expected to move on and Mark Vientos shifting to first base, the Mets have an opening at the hot corner. Baty has slashed just .215/.282/.325 over 169 games at the big-league level, but he's still only 25 and is a former top prospect. It's possible the Mets go outside the organization for additional competition at third base, but for now Baty will battle Ronny Mauricio (knee) and Luisangel Acuna for the gig.

The Mariners acquired Mastrobuoni from the Cubs on Tuesday in exchange for cash considerations, Meghan Montemurro of the Chicago Tribune reports.

Mastrobuoni had been designated for assignment but will now get to join a new 40-man roster. A .219/.279/.263 hitter across 272 career plate appearances in the majors, the utility player will compete for a reserve role this spring but does have minor-league options remaining.

Alvarez signed a minor-league contract with the Twins on Jan. 2.

Alvarez spent the 2024 campaign with the Athletics organization, batting .315 with 15 home runs, 54 RBI, 46 runs scored and four stolen bases over 75 games with Triple-A Las Vegas. Additionally, the 30-year-old played in 16 games with the A's, batting .243 with a double, two RBI, seven runs scored and a stolen base over 37 at-bats. Alvarez will report to Triple-A St. Paul ahead of the 2025 season, and he'll look to impress in order to potentially garner a shot with the Twins' major-league roster at some point during the year.
