Jake Eder joined the Chicago White Sox organization in a 2023 trade deadline deal that sent infielder Jake Burger to the Miami Marlins.

Cristian Mena ranked among the minor-league leaders in strikeouts.

The Sox added both pitching prospects to their 40-man roster Tuesday.

Tuesday was the deadline for teams to add to their 40-man rosters and protect eligible players from the Rule 5 draft on Dec. 6.

Eder, 24, went 0-3 with an 11.42 ERA in five starts at Double-A Birmingham after being acquired in the Aug. 1 trade. He had 22 strikeouts in 17 1/3 innings.

Overall in 2023, the left-hander had a combined 2-6 record with a 6.35 ERA and 70 strikeouts in 14 starts between Class A Jupiter and Double-A Pensacola in the Marlins organization and with the Barons.

Eder also made six appearances (five starts) with the Glendale Desert Dogs of the Arizona Fall League, going 1-1 with a 6.11 ERA. He struck out 16 batters in 17 2/3 innings.

Eder was originally selected by the Marlins in the fourth round of the 2020 draft out of Vanderbilt and is 5-11 with a 3.80 ERA and 169 strikeouts in 29 starts during two minor-league seasons. He missed all of 2022 while recovering from Tommy John surgery.

He is the No. 5 prospect in the Sox organization, according to MLB.com.

Mena, 20, is ranked the No. 10 prospect in the Sox system by MLB.com. The right-hander went a combined 8-7 with a 4.85 ERA and 156 strikeouts in 27 starts between Birmingham and Triple-A Charlotte in 2023.

He was 7-6 with a 4.66 ERA in 23 starts for the Barons and 1-1 with a 5.95 ERA in four starts for the Knights.

Mena finished 15th among all minor-league pitchers in strikeouts. He ranked first among the Sox organizational leaders in strikeouts and innings (133 2/3), tied for first in starts and tied for second in victories.

Originally signed as an international free agent from the Dominican Republic on July 2, 2019, Mena is 11-17 with a 4.97 ERA and 344 strikeouts in 64 career games (63 starts) during three minor-league seasons in the Sox organization.

With Tuesday’s moves, the Sox 40-man roster increases to 37.
