The Orioles’ crowded outfield was a preseason strength. It’s thinned itself with performance and platoons.

With Mountcastle out of the outfield picture and Hays and Stewart sharing left field, there’s an opportunity for another player to emerge, but the two outfield prospects on Baltimore’s 40-man roster haven’t capitalized. Hays’ injury meant Ryan McKenna made his major league debut early in the season, and while he’s thrived in Triple-A with 11 home runs and a 1.106 OPS in 27 games, his major league OPS is .615. Yusniel Diaz, the former top prospect acquired as the centerpiece of the trade that sent Manny Machado to the Los Angeles Dodgers, has dealt with injuries throughout the year and hasn’t performed when on the field, posting a .509 OPS between Norfolk and Double-A Bowie while striking out nearly 30% of the time.
