Cedric Mullins was the most exciting thing about the Orioles last season. There’s room for debate there, of course, but in a campaign so packed with disappointment, he stuck out as a rare ray of hope. His skill set (speed, athleticism, defense) had become a foreign concept in Baltimore, and his impressive debut (3-for-4, two doubles, two RBI, a walk) made for the most interesting baseball viewing of the year. But the shine of being the “fresh-faced rookie” wears off quickly. The Orioles are rebuilding, and there will be plenty of opportunities for young players to prove themselves, but Mullins plays one of the most competitive positions in the organization, so he will need to make 2019 count.
