The Mariners optioned Diaz to their spring training complex Monday.

The move makes room on the Mariners' 28-man active roster for right-handed reliever Gregory Santos (biceps), who was reinstated from the 15-day injured list. Diaz had made two appearances for the big club since being recalled Sept. 1, allowing one hit and one walk while striking out three over 3.1 scoreless innings.

The Mariners reinstated Santos (biceps) from the 15-day injured list Monday, Daniel Kramer of MLB.com reports.

Santos had been on the injured list since Aug. 2 due to right biceps inflammation. He began his rehab assignment with Triple-A Tacoma in early September, and across six outings he allowed one run on two hits and seven walks while striking out six across 5.1 frames. Santos has joined the Mariners in Houston and will operate out of the bullpen as Seattle makes a final push for a wild-card spot. To make room on the big-league roster for Santos, left-hander Jhonathan Diaz was optioned to the minors.

Red Sox manager Alex Cora said Sunday that he will "mix and match" at closer with Slaten and Chris Martin following the season-ending injury to Kenley Jansen (shoulder), Gabrielle Starr of the Boston Herald reports.

Slaten has looked sharp since returning from his elbow injury last month, posting a 1.69 ERA and 12:2 K:BB over 10.2 innings covering 11 appearances. Cora indicated Sunday that he envisions the Rule 5 pick as a potential long-term closer option, and the 27-year-old could get a look in the role this week. Jansen is an impending free agent, so Boston will be looking for a new closer next season.

Red Sox manager Alex Cora said Sunday that he will "mix and match" at closer with Martin and Justin Slaten following the injury to Kenley Jansen (shoulder), Gabrielle Starr of the Boston Herald reports.

Martin stepped into the closer role for the Red Sox late last season after Jansen's campaign ended prematurely and will now be in the mix for saves again for the final week of this year. The veteran reliever has put up a 3.48 ERA and superb 48:2 K:BB over 41.1 innings out of Boston's bullpen this season.

The Cubs claimed Paredes off waivers from the Brewers on Monday, Sahadev Sharma of The Athletic reports.

Paredes will remain in the division after the Brewers booted him from their 40-man roster after he posted a 1.74 ERA and 14:10 K:BB over 20.2 innings in the big leagues. The 28-year-old does not have any minor-league options remaining, so he will be added to the Cubs' 28-man active roster.

The Red Sox placed Jansen on the 15-day injured list Monday with right shoulder inflammation, Jen McCaffrey of The Athletic reports.

The move was reported Sunday and now the transaction is official, which ends Jansen's season. Jansen has battled through a shoulder problem throughout this month, and since the Red Sox are out of the playoff hunt, they have opted to go ahead and shut him down. The Red Sox will turn to Chris Martin and Justin Slaten as closer options over the final week of the season. Jansen will be a free agent this offseason and has likely thrown his last pitch for the Red Sox.

The Cubs recalled Hollowell from Triple-A Iowa on Monday, Sahadev Sharma of The Athletic reports.

Hollowell was claimed off waivers from the Diamondbacks in August and will now get his first stint in the majors with the Cubs. The 26-year-old holds a 4.94 ERA and 45:21 K:BB across 31 innings this season at the Triple-A level.

The Cubs optioned Wingenter to Triple-A Iowa on Monday, Sahadev Sharma of The Athletic reports.

Wingenter has made five relief appearances for the Cubs this season, allowing two runs with a 3:2 K:BB over six frames. He had pitched both of the last two days, so the Cubs are replacing him with a fresh arm in Gavin Hollowell, who was recalled from Triple-A in a corresponding move.

The Cubs recalled Kilian from Triple-A Iowa on Monday, Maddie Lee of the Chicago Sun-Times reports.

Right-hander Nate Pearson is serving as the Cubs' opening pitcher for Monday's game in Philadelphia, but he's likely to cover only an inning or two before turning the contest over to the bullpen. Kilian will be available out of the bullpen and may end up taking on a bulk-relief role for the Cubs, as his final start with Iowa came six days earlier. Kilian made three appearances (one start) for the Cubs in 2023 but has pitched exclusively in the minors in 2024, turning in a 3.22 ERA, 1.15 WHIP and 38:14 K:BB over 44.2 innings with Iowa.

The Cubs placed Lopez on the 15-day injured list Monday with a right groin strain, Sahadev Sharma of The Athletic reports.

Lopez returned from the same injury just last week, so he evidently must have suffered a setback. The injury ends what was a nice bounce-back season for Lopez, who collected a 2.89 ERA and 50:19 K:BB over 53 innings covering 52 appearances for the Mets and Cubs. He'll be a free agent this offseason.
