It’s the first MLB call for Marsh. Kansas City selected the 6’2″ hurler 70th overall in the 2019 draft out of Arizona State. Marsh has ranked around the middle tier of a generally thin K.C. farm system. Baseball America recently slotted him 11th among organizational prospects, while Keith Law of the Athletic placed him 20th coming into the year.
Marsh was coming off a brutal 2022 showing in Double-A, when huge home run issues led to a 7.32 ERA over 25 starts. Prospect evaluators still credited him with swing-and-miss potential on a low-mid 90s fastball and an above-average to plus slider. The Royals added him to the 40-man roster last offseason to keep him out of the Rule 5 draft despite the poor numbers.
The 25-year-old has found a little better results this time around. Over 11 starts with Double-A Northwest Arkansas, he posted a 5.32 ERA. Marsh got the homers in check and struck out a solid 26.4% of opponents but walked more than 11% of batters faced. He has similar strikeout and walk marks in three starts since being bumped up to Triple-A Omaha, where he’s allowed just four runs in 15 innings.
It’s possible this is just a spot start necessitated by Lyles’ illness. Kansas City hasn’t gotten much production out of its rotation overall, though, so there should be other opportunities for Marsh to work his way back in the relatively near future if he shows well in Omaha.
