The Mets claimed De Los Santos off waivers from the Blue Jays on Monday, Michael Mayer of MetsmerizedOnline.com reports.

De Los Santos, 26, got a cup of coffee with the Blue Jays in 2024 but spent most of the season at Triple-A Buffalo, where he hit .260/.375/.441 with six homers over 43 games. He is capable of playing every infield position as well as left field.

The Diamondbacks exercised Suarez's $15 million club option for 2025 on Friday, Jesse Rogers of ESPN.com reports.

Suarez reached the 30-HR and 100-RBI benchmarks while slashing .256/.319/.469 in his first season with the Diamondbacks. Now that he's officially locked in for the 2025 campaign, he'll almost certainly retain his everyday role at third base.

Urias elected free agency Friday.

He cleared waivers after being removed from the Mariners' 40-man roster and has decided not to accept an outright assignment to the minors. Urias, 27, managed just a .191/.303/.394 slash line in 41 games with Seattle this season.

Alvarez cleared waivers Thursday and was sent outright to Triple-A Las Vegas.

The 30-year-old Alvarez posted a .967 OPS in Triple-A across 317 plate appearances in 2024 and reached the majors for the first time, going 9-for-37 with two RBI over 16 games. However, he no longer owns a spot on the Athletics' 40-man roster and will remain in Las Vegas as organizational depth.

The White Sox declined Moncada's $25 million club option for 2025, Francys Romero of BeisbolFR.com reports.

The veteran infielder will be given a $5 million buyout. It was an obvious move, given where the White Sox' roster stands and the fact that Moncada was limited to just 12 games in 2024 and 92 games in 2023 due to injury. Moncada won't turn 30 until May, but durability concerns and inconsistent production could point to a bearish market this winter.

Chisholm will start at third base and bat cleanup Wednesday in Game 5 of the World Series versus the Dodgers.

Chisholm was moved up from the No. 5 spot to the No. 4 spot in the Yankees' Game 4 victory and manager Aaron Boone will keep him there for Game 5 after Chisholm reached twice and stole a base Tuesday. Giancarlo Stanton will hit fifth for the second straight contest.

Leblanc elected free agency Monday.

The Angels booted Leblanc from their 40-man roster last week and because he had been outrighted before, he had the right to choose free agency and has done just that. Leblanc is a career .254/.330/.412 hitter over parts of two big-league seasons.

Manager Aaron Boone said Friday that Berti was left off the Yankees' World Series roster due to a right hip flexor injury, Bryan Hoch of MLB.com reports.

The Yankees skipper noted that Berti's injury occurred while he was running the bases in Game 4 of the ALCS, and he would have been part of the roster had he not gotten hurt. Because of the utility man's absence, Nestor Cortes (elbow) will rejoin New York's roster to provide additional pitching depth for the World Series.

Dodgers manager Dave Roberts said Friday that Hernandez will be in the lineup every day during the World Series, Bill Plunkett of The Orange County Register reports.

He's starting in center field and batting sixth in Game 1. His position may change from game to game, but Hernandez should remain in the Dodgers' lineup for each of the Fall Classic games. He's slashing .303/.378/.485 with two homers this postseason and has slugged 15 home runs over 81 career playoff contests.

Berti is not on the Yankees' World Series roster.

Berti has made three starts at first base against lefties this postseason, but the Yankees have elected to carry Nestor Cortes (elbow) on their World Series roster instead. With Berti off the roster, the Yankees will either start Anthony Rizzo or Oswaldo Cabrera at first base versus left-handers.
