I had a limited, three at-bat look at Mejia in the game, but the switch-hitting Mejia looks to be a projectable above-average major leaguer catcher at this point in his development, and he, along with Rafael Devers (3B, Red Sox), was one of the youngest participants in the All-Star game at just 21 years old. Signed as a non-drafted free agent out of the Dominican Republic in 2012, Mejia has a small, compact frame, but he showed surprising pop in his BP sessions, and its not a stretch to project a plus hit tool with average power, given that he is showing his bat off in the Eastern League this year, leading the league with a .336 average, and with 28 of his 78 hits going for extra bases (16 doubles, two triples, and 10 home runs). While he shows good barrel control from both sides of the plate, he looks to be more advanced and productive hitting from the right side, where he is hitting .475 versus lefties in 58 at-bats. From both sides of the plate he shows the ability to get the bat head out and barrel the ball up to all fields. On defense, he shows average receiving actions, mobility, and range, and his arm is plus, with good carry and average accuracy. The hit tool and average defense should give him a floor of at least a Role 50, average major leaguer, but if the hit tool continues to mature as it has, he could hit a ceiling of a Role 60, above-average receiver.
