First baseman Josh Naylor and the Seattle Mariners are finalizing a five-year contract on Sunday evening, sources familiar with the deal told ESPN's Jeff Passan. The Mariners will now keep Naylor around for the foreseeable future after acquiring him at this year's trade deadline from the Arizona Diamondbacks. The 28-year-old Canadian left-handed slugger hit .299 (58-for-194) with nine home runs, 33 RBI, 32 runs scored, and 19 stolen bases in 54 regular-season games after being traded to Seattle. Overall, he slashed a strong .295/.353/.462 with an .816 OPS, 20 home runs, 92 RBI, 81 runs scored, and a career-high 30 stolen bases in 147 games in his seventh year in the majors. Naylor ranked in the 66th percentile in xwOBA, 42nd percentile in xBA, and 43rd percentile in hard-hit rate, suggesting his 31-homer campaign in 2024 is a ceiling that could be hard to reach again. Fantasy managers also shouldn't expect a repeat in the steals department, with his previous high-water mark in that category being 10.

Free-agent first baseman/designated hitter Joey Meneses signed a minor-league deal with the Athletics on Saturday, sources told Francys Romero. Meneses did not surface in the big leagues during the 2025 season, instead spending all of his time at Triple-A Syracuse in the New York Mets' organization, where he slashed .264/.321/.444 with 11 home runs, 55 RBI, and 37 runs scored in 421 plate appearances. The 33-year-old Mexican debuted in the majors in 2022 with the Washington Nationals and hit a combined .274/.322/.408 with a .731 OPS, 29 home runs, 165 RBI, and 123 runs scored in 286 games over three seasons in D.C. The 33-year-old will be fighting for an Opening Day roster spot with the A's at spring training in 2026, but if he makes the squad, he'll merely be a right-handed-hitting option off the bench. Meneses hit 13 homers and drove in 89 in a career-high 154 games for the Nats in 2023.

Los Angeles Dodgers outfielder Enrique Hernandez (elbow) announced that he had left-elbow surgery on Friday for an injury that he played through during the second half of the regular season and into the playoffs, according to Jack Harris of the Los Angeles Times. Hernandez said it will prevent him from playing for Team Puerto Rico in the 2026 World Baseball Classic next spring. It's unclear if the 34-year-old veteran will be delayed for the start of the 2026 regular season. Kike barely hit over .200 during 92 regular-season games for L.A. while adding 10 home runs, 35 RBI, and 30 runs scored in 256 plate appearances. He was better during the playoffs, though, going 16-for-64 (.250) with a homer and seven RBI to help the Dodgers win back-to-back World Series championships. Hernandez is an unrestricted free agent this offseason and won't be much of a fantasy target, regardless of where he lands.

The Athletic's Ken Rosenthal writes that a "perfect storm" for the New York Mets to lose free-agent closer Edwin Diaz "might be developing." Diaz opted out of the final two years of his contract with the Mets and will test free agency for the first time in his career. The Toronto Blue Jays, who were two outs away from winning the World Series before closer Jeff Hoffman blew it, are poised to spend big and are among the teams interested in adding Diaz. The 31-year-old Diaz said on Thursday that his chances of returning to the Mets are "50-50," and according to a person briefed on his wishes, he wants the same kind of deal he signed with the Mets in 2022 -- five years and $102 million. Toronto met with Diaz's agents during the GM meetings this week in Las Vegas and is targeting high-leverage relief as well as starting pitching. If they were to land Diaz in free agency, they'd almost certainly slide Hoffman to the eighth inning.
