Left-hander opted out of a minor league contract with the Royals, as first reported by MLBTRs Tim Dierkes ( ). He returns to free agency after K.C. decided not to select him onto the 40-man roster. Cox was a fifth-round pick by the Royals out of Mercer in 2018 James Johnson Jersey . He had spent all but one day of his profe sional career in the organization. The 27-year-old southpaw reached the majors last season and pitched in 24 games. He turned in a 4.54 ERA acro s 35 2/3 innings, striking out 22.1% of opponents against an elevated 11.4% walk percentage. His debut season came to an unfortunate end in September. Cox tore the ACL in his left knee as he tried to cover first base on a ground-ball. He underwent surgery not long thereafter. That perhaps contributed to the Royals decision to take Cox off the 40-man roster. K.C. non-tendered him on November 17. That briefly sent him to free agency, though he returned to the organization on a minor league deal the following day. Cox wasnt able to participate in Spring Training as he finished his injury rehab, but he made it back to the mound with Triple-A Omaha a couple weeks into the season. Cox made 19 appearances with the Storm Chasers, working mostly in long relief. He worked to a 3.90 ERA with a decent 23.3% strikeout rate. Yet he also walked almost 14% of opponents, an i sue hes battled throughout his career. Cox is likely looking at another minor league deal on a team seeking multi-inning relief depth.
