Top Orioles prospect Coby Mayo will see his initial taste of the majors draw to a close after just seven games and 20 plate appearances. Baltimore announced Thursday that Mayo has been optioned back to Triple-A Norfolk. Infielder Livan Soto was recalled from Norfolk in his place.
Mayo, regarded as one of the top prospects not just in Baltimore’s system but in all of baseball, was called up shortly after third baseman Jordan Westburg suffered a fractured hand when he was hit by a pitch.
Expectations were high, considering his prominent placement on national prospect rankings and his gaudy .301/.375/.586 batting line through 341 Triple-A plate appearances during just his age-22 season. However, like fellow top prospect Jackson Holliday before him, Mayo stumbled out of the gate with a strikeout-laden showing and was sent back to Triple-A in fairly short order. He went just 1-for-17 with three walks and 10 strikeouts in those 20 trips to the plate.
There’s no sense in making any long-term judgment on Mayo based on a tough week in his first glimpse of the majors. Many detractors were quick to write Holliday off after similar early struggles, and he’s returned from Norfolk with a .255/.314/.596 line and five home runs in 51 plate appearances. Twenty ugly plate appearances don’t say anything about Mayo’s long-term future other than that he might yet need a bit more work in the upper minors before he gets his next big league audition.
In sending Mayo back to Norfolk, the O’s seem to be committing to Ramon Urias as the primary third baseman in Westburg’s absence — although Soto could also see some run at the hot corner. The Orioles could also retain Mayo’s prospect/rookie status for the 2025 season as well, which would put them in position to potentially land a draft pick if he finishes well enough in ’25 Rookie of the Year voting. So long as Mayo finishes with fewer than 130 at-bats and fewer than 45 days on the active roster, he’ll still be eligible for that benefit. If that were a primary concern for them, they likely wouldn’t have brought Mayo to the big leagues in the first place, but retaining that possibility is now surely seen as an ancillary benefit of today’s move.
Urias, 30, seems likeliest to garner additional playing time. He drew sensational defensive marks at third base just two seasons ago, but both Defensive Runs Saved and Outs Above Average have soured on his glovework at the position. At the plate, Urias has turned in a .236/.306/.372 slash at the plate this season, sitting about 5% worse than league-average overall (by measure of wRC+).
As for Soto, he’s hit extremely well in a small sample of 74 plate appearances, batting .358/.397/.507 dating back to 2022. It should be emphasized that his line is propped up by a gargantuan .451 average on balls in play that he won’t sustain, and Soto has a much more modest track record in Triple-A, where he’s hit .267/.364/.386 in 709 plate appearances as a utilityman.
