White Sox Select Jake Eder, Cristian Mena

The White Sox have selected the contracts of lefty Jake Eder and right-hander Cristian Mena, per a team announcement. Both are now protected from next month’s Rule 5 Draft. Chicago’s 40-man roster is now up to 37 players.

Eder, 25, is one of the organization’s top pitching prospects. The Sox picked up the former fourth-round pick from the Marlins in the deadline swap that sent corner infielder Jake Burger from Chicago to Miami. Eder, in his first season back from Tommy John surgery, pitched to a 3.94 ERA with a 30.6% strikeout rate in 29 1/3 Double-A frames prior to the swap but perhaps began to wear down late in the season after a lengthy layoff from pitching. He walked 15 hitters in 17 1/3 innings with the Sox following the trade and issued another 15 free passes in 17 2/3 innings of Arizona Fall League play.

Despite the shaky finish to the season, there’s little doubting Eder would’ve been selected in the Rule 5 Draft had he remained unprotected. The lefty ranked as baseball’s No. 62 overall prospect at FanGraphs in 2022 after pitching 71 1/3 innings of 1.77 ERA ball as a 22-year-old in Double-A. He’ll either return to Double-A to begin the 2024 season or jump up to Triple-A — and either way that’ll put him within general proximity of reaching the big leagues.

Mena, 20, has had a meteoric rise through the White Sox’ system, splitting the 2023 season between Double-A and Triple-A. After working to a 3.80 ERA across three levels as a 19-year-old in 2022, he posted a combined 4.85 ERA in 133 2/3 innings this year. While the earned run average certainly doesn’t jump out, Mena was four years younger than the average age of his Double-A opposition and nearly seven years younger than his average opponent in Triple-A. Despite that youth and lack of experience, he managed a 26.9% strikeout rate. His 11% walk rate speaks to a need to hone his command, but Mena has a heater that reaches 96 mph and a curveball that Baseball America (who ranks him sixth among Chicago prospects) touts as a plus pitch.
