Ketel Marte Just Became Arizonas Messiest Offseason Question

As the MLB offseason kicks into gear, Bo Bichette's contract decision and looming trade prospects stir the baseball rumor mill with significant implications.

The Mets have one less offseason question to answer after Bo Bichette made his decision. The infielder has picked up his $42 million player option for 2027, according to The Athletic, and he still holds another $42 million player option for 2028.

Bichette’s first year in Queens did not go smoothly. The 28-year-old finished with a .702 OPS and 18 home runs while working through the move from shortstop to third base.

For now, that leaves the Mets with Bichette at third, Francisco Lindor at short, and Marcus Semien at second. First base remains unresolved, and a trade is still in play if the Mets decide to rework that veteran infield.

Semien would be the ideal player to move, though that may not be realistic. Lindor’s name is also expected to surface in trade chatter this winter.

Another infielder could be on the move out west. The Diamondbacks are expected to listen to offers for second baseman Ketel Marte, according to the Arizona Republic.

Arizona explored trade interest last offseason but never found a match. Marte has full no-trade protection, so he controls where he goes if he wants out at all, and it’s not known whether he even wants a change of scenery.

The 33-year-old’s 2026 season fell short of his usual standard. He also went AWOL in August, which led the Diamondbacks to place him on the restricted list.

Torey Lovullo later said that was the fourth straight season Marte had missed a game without permission. Any team interested in him will have to balance the production with the possibility of clubhouse issues.

Over in Japan, the Seibu Lions will post right-hander Kaima Taira, making him available to MLB clubs through the posting system, the team announced Friday. That move is expected to become official in the coming days. Once it does, Taira will have 45 days to reach a deal with an MLB team before returning to Japan in 2027.

Taira checked in as the 19th-best free agent on the list, and there’s plenty to like in the profile. He stands 5-foot-8 but gets extreme extension down the mound, almost seven feet, which helps create a tough release point for hitters to pick up.

He brings a mid-90s four-seam fastball and backs it up with a cutter, sinker, sweeper, slider, changeup, and splitter. The Seibu Lions used him as a reliever in 2024 and 2025 before moving him into the rotation in 2026, and he handled the job well.

His breaking stuff is only average, and pitchers his size don’t usually hold up for long as starters, so a team signing him may try him there first while keeping open the possibility that he settles in as a reliever or multi-inning setup arm.

Last season, Taira posted a 1.36 ERA with 141 strikeouts over 146 innings. His ERAs were actually higher in relief in both 2024 and 2025, but he has been excellent in Japan overall and owns the kind of swing-and-miss arsenal that can translate to MLB. He should draw plenty of interest in the coming weeks.

The Red Sox were also active in the first wave of offseason trades. On Thursday, they sent utility man Nate Eaton to the Athletics for minor-league right-hander Jareth Rayo, the team announced. The A’s recently hired former Red Sox assistant general manager Taylor Smith as their president of baseball operations, and his first move was bringing in Eaton, a player he likely knows well from their time together in Boston.

Boston then moved infielder Tsung-Che Cheng to the Tigers for cash, the team announced. Cheng, 25, is a glove-first utility player who appeared in 14 games for the Red Sox this season. Those two deals also cleared two 40-man roster spots, but Boston still needs to open three more to fit its seven players on the 60-day injured list.
