The Rockies returned Rule 5 pick Petit (elbow) to the Tigers on Tuesday.

Petit was taken in the Rule 5 Draft by Colorado last winter but never pitched for the Rockies, as he missed the season after undergoing Tommy John surgery with an internal brace on his right elbow in March. The 6-foot-8 right-hander should be ready to pitch right around midseason in 2027.

The Cardinals acquired Rivera from the Red Sox on Tuesday in exchange for Juan Garcia, Andrew Parker of SoxProspects.com reports.

Rivera had been designated for assignment Monday as the Red Sox did some 40-man roster housekeeping. The big lefty allowed seven runs over 10 innings during his brief time in the majors in 2026, and he posted a 2.96 ERA and 55:27 K:BB across 45.2 frames with Triple-A Worcester. Rivera will compete for a spot in the Cardinals' bullpen in 2027, but he has minor-league options remaining.

The Blue Jays outrighted Van Eyk to Triple-A Buffalo on Monday.

Van Eyk made five appearances (one start) for the Blue Jays in 2026, giving up eight runs (seven earned) over 11.2 frames. The 28-year-old is no longer on Toronto's 40-man roster, but he'll stick around in the organization as swingman depth.

The Mariners outrighted Watson to Triple-A Tacoma on Monday.

Watson was a waiver claim of the Mariners back in August, but the righty has yet to make his major-league debut. He's no longer on the 40-man roster but will remain in the organization.

The Mariners outrighted Simpson to Triple-A Tacoma on Monday.

Simpson has logged a 7.82 ERA but has 46 strikeouts in 38 innings during his time in the big leagues. He's no longer on the Mariners' 40-man roster.

The Mariners outrighted Wisdom to Triple-A Tacoma on Monday.

Wisdom will exit the 40-man roster heading into the offseason and is likely to become a free agent. The 35-year-old went 5-for-47 with a 3:21 BB:K in 19 contests during his time with the Mariners this season.

San Francisco declined Wick's (elbow) club option for the 2027 season Monday.

Wick will remain with the organization and is arbitration eligible. He was unable to pitch during the 2026 while rehabbing from Tommy John surgery.

Horn (elbow) was released by the Tigers on Monday.

Horn underwent Tommy John surgery in July and will presumably remain out for the majority of the 2027 season while rehabbing. He last appeared in the big leagues in 2025 with Detroit, posting a 1.59 ERA and 1.59 WHIP with a 10:7 K:BB across 11.1 innings.

Diaz was designated for assignment by the Tigers on Monday.

Diaz was scooped up off waivers from the Diamondbacks in June, though he didn't perform well when given his opportunities in the big leagues. He'll head to the waiver wire after losing out on a 40-man roster spot.

Austin (knee) was outrighted to Triple-A Iowa on Monday.

Austin underwent right knee surgery in March, though it's currently unclear where he's at in his rehab. He'll remain with the organization but is no longer a member of the 40-man roster following Monday's transaction.
