The Tigers selected Flores to their 40-man roster Tuesday.

Flores is now protected from selection in next month's Rule 5 Draft, though he's likely still far away from making his major-league debut. The 22-year-old right-hander posted a 4.65 ERA and 90:33 K:BB in 89 innings (21 starts) this past season between High-A West Michigan and Double-A Erie.

The Red Sox selected Perales to their 40-man roster Tuesday, Chris Cotillo of The Springfield Republican reports.

Perales is only 20 years old and still pretty far away from reaching the majors, but Boston has opted to protect him from being plucked away in next month's Rule 5 Draft. The young right-hander posted a 3.91 ERA and 115:50 K:BB over 89.2 innings (21 starts) this past season between Low-A Salem and High-A Greenville.

The Blue Jays selected Macko to their 40-man roster Tuesday.

Macko is now protected from selection in next month's Rule 5 Draft. The 22-year-old left-hander registered a 4.81 ERA, 1.35 WHIP and 106:40 K:BB over 86 innings (20 starts) this past season with High-A Vancouver.

The White Sox selected Mena to their 40-man roster Tuesday, Vinnie Duber of AllCHGO.com reports.

Mena is now protected from next month's Rule 5 Draft. He held a 4.85 ERA, 1.41 WHIP and 156:64 K:BB in 133.2 innings this past season between Double-A Birmingham and Triple-A Charlotte.

The White Sox selected Eder to their 40-man roster Tuesday, Vinnie Duber of AllCHGO.com reports.

Eder posted an ugly 6.35 ERA over 56.2 minor-league innings in 2023, but the White Sox acquired him from the Marlins in the Jake Burger trade and didn't want to lose the 25-year-old left-hander in the upcoming Rule 5 Draft.

Thomas was designated for assignment by the Cardinals on Tuesday.

Thomas, 25, struggled to a 5.53 ERA, 1.75 WHIP and 69:31 K:BB over 94.1 innings (17 starts, four relief appearances) this past season with Triple-A Memphis. He is no longer part of the 40-man roster in St. Louis.

The Cardinals selected Robberse to their 40-man roster Tuesday.

Robberse was acquired from the Blue Jays this past July as part of the Jordan Hicks trade and is now protected from being plucked away by another organization in the upcoming Rule 5 Draft. The 22-year-old right-hander posted a 4.28 ERA and 130:57 K:BB in 124 innings this past summer between Double-A and Triple-A.

The Cardinals selected Kloffenstein to their 40-man roster Tuesday.

Kloffenstein earned his way into the 40-man roster mix in St. Louis after pitching to a 3.16 ERA, 1.27 WHIP and 140:55 K:BB over 128 innings this past season between the Double-A and Triple-A levels. The 23-year-old right-hander could be a consideration for the major-league rotation at some point in 2024.

The Athletics selected Salinas to their 40-man roster Tuesday.

Salinas registered an underwhelming 5.48 ERA over 67.1 innings this past season with Double-A Midland, but he has racked up 372 strikeouts in 253 career minor-league frames. The 22-year-old right-hander is now protected from being plucked away from the A's in the upcoming Rule 5 Draft.

Chirinos (elbow) was designated for assignment by Atlanta on Tuesday.

The move frees up a spot on the 40-man roster for waiver claim Penn Murfee. Chirinos had seemed likely to be non-tendered, anyway, after posting a 5.40 ERA over 20 appearances for Tampa Bay and Atlanta in 2023. He ended the season on the 60-day injured list with an elbow problem and it's not clear what his current health status is.
