In one of the more obscure deadline trades today the Oakland Athletics shipped veteran infielder Adam Rosales to the Arizona Diamondbacks for right-handed pitcher Jeferson Mejia. Who is Jeferson Mejia? Here’s a quick look.
Jeferson Mejia, RHP: Mejia was originally signed by the Chicago Cubs out of the Dominican Republic in 2013. He was one of the more interesting prospects on the international market that year, earning an $850,000 bonus. After a promising 2014 debut in rookie ball (2.45, 45/17 K/BB in 40 innings) he was traded to Arizona in the December 2014 Miguel Montero deal.
It has been downhill from there, as Mejia never put things together in the Dbacks system. 2017 has been typical: he posted a 6.08 ERA in 24 innings in Low-A with a 27/22 K/BB, which got him demoted to the Northwest League on July 16th. He’s walked three in five innings there, also fanning eight.
Mejia is 6-7, 200 pounds, born August 2nd, 1994. He can hit 93 MPH but his breaking ball is below average and his control is terrible. He’s a definite project at this point, a raw arm.
