Valencia, 33, joined the Baltimore organization on a minors deal but had played a fairly significant role on the roster for much of the season. Over 282 plate appearances, he carries a .263/.316/.408 batting line — good for an exactly league average 100 OPS+ (albeit only a 93 wRC+).
Though he has mostly lined up at third base, Valencia has also spent time in right field for the O’s. He’s not generally regarded as much of a defender, and the advanced metrics have reflected that reputation this year.
It’s perhaps not out of question that a contending organization in search of a bench threat against left-handed pitching could put in a claim. As he has for much of his career, after all, Valencia has bludgeoned opposing southpaws this year. He’s also earning a palatable $1.2MM salary for the season.
As for Mullins, the diminutive 23-year-old will make his MLB debut. He has steadily ascended the ladder since joining the Orioles organization as a 13th-round pick in 2015. This season, he knocked around Double-A pitching before earning a promotion to the highest level of the minors, where he carries a .267/.332/.425 slash with five home runs and a dozen steals over 267 plate appearances.
